Dental Disease in Pets

Dental disease is not just about bad breath! Dental disease is painful! 80% of dogs and cats over 3 years of age have dental disease. Infections from poor dental health can cause permanent damage to the kidneys, liver and heart. Many pets will continue to eat, even while painful, and show little sign of their poor dental health. Our goal is to treat dental disease at Grade 2-3 to prevent permanent damage to the internal organs that occurs when dental disease progresses to Grade 4.

Effects on the Body

Healthy mouth allows pet to eat without pain.
Grade I – Gingivitis
Redness on gumline and plaque forming.
Grade 2 – Early Periodontitis
Tissue swelling and loss of tooth attachment. Gums may bleed. Mouth starts to get painful and odor is noticeable.
Grade 3 – Moderate Periodontitis
50% of the attachment of tooth is lost. Roots are exposed. Gums often bleed when probed. Bad breath is present. Pain associated with the teeth may start to change the pet’s behavior.
Grade 4 – Advanced Periodontitis
Teeth may fall out. Usually blood and pus are present. Bacteria spread through the body via the bloodstream and can damage the liver, kidneys, and heart.

Recommendations to Slow Periodontal Disease Progression

It is important to note that dental disease is progressive and will worsen over time. Prevention and maintenance are key to ensuring longevity of the teeth. We also recommend the following to help slow progression of disease. Please note that these recommendations offer no help in cases of severe disease, such as Grade 3 and Grade 4. Patients with Grade 3 & Grade 4 periodontal disease will require extractions and aggressive therapy.
Teeth Brushing: Brushing daily with a pet toothpaste and tooth brush or dental wipes is very beneficial in preventing tartar accumulation.

Diet: Feed a dental health diet such as Hill’s T/D or Royal Canin Dental. These diets are designed to help remove tartar from the tooth as the patient eats.

Treats: Feed dental treats such as Oravet Dental Chews. Not all treats actually benefit oral health. Use only treats approved by the Veterinary Oral Health Council.

Oral Rinse: Use an oral rinse such as Hexarinse.

Water Additives: You may add solutions such as Aquadent to the drinking water.

What is the Veterinary Oral Health Council?

The Veterinary Oral Health Council (VOHC) is made up of board-certified veterinarians with advanced certification as dentistry specialists and dental scientists. These council members are appointed by the president and Board of Directors of the American Veterinary Dental College. The council reviews submissions and recommends whether items are awarded a seal of approval from the VOHC.

What Does the VOHC Seal Mean?

The VOHC Seal indicates that a pet dental product has met pre-set standards that prove that it slows dental plaque and dental tartar accumulation on teeth. Approval indicates that the product has undergone trials created by the VOHC. There are many products on the market that make a claim “to improve dental health”. We encourage you to find product with a VOHC Seal.

Canine Parvovirus

Canine Parvovirus Recovery and Environmental Decontamination
Allegheny Veterinary Services


Your pet is recovering from extensive damage to the intestinal tract. It is typical for stool to be a little loose at first or for no stool to be produced for a few days as the tract recovers. The stool should gradually firm up over the first 3 to 5 days at home.

Your pet may resume normal activity and attitude over the first week at home. If diarrhea persists, vomiting occurs, or your pet seems depressed, please contact our office at once for further instructions.

Your pet may be ravenously hungry after going so long without food. Do not allow him to gorge as this can result in further vomiting or diarrhea. Feed smaller meals separated by at least an hour or two.

• Feed the therapeutic diet we have provided for the first few days at home. Then resume the normal diet. Do not feed table scraps. Stick to the diet recommended by your veterinarian.


Your pet should be considered contagious to other puppies for at least 6 weeks. Therefore, trips to the park, obedience school, or visiting other neighborhood areas where pets comingle, should be avoided during this time. If your pet is less than 16 weeks of age, he should not be allowed in public areas until the vaccination series is fully completed. He can be considered immune to parvovirus after recovery. However, puppy vaccinations include many other infectious diseases for which your pet needs to be vaccinated against.

Other Pets

Humans are not susceptible to canine parvovirus infection, though some strains can be contagious to cats. Adult dogs that have been vaccinated are not susceptible either. Introducing new puppies poses a problem as the parvovirus persists a long time in the environment. When in doubt, make the new puppy an older individual (16 weeks or so) who has already completed his/her vaccination series. Any obviously contaminated material should be removed (fecal- or vomit-contaminated objects that cannot be bleached, any remaining areas of feces, etc.). See section below on Decontamination of the Environment.


Your pet may be bathed any time as long as you do not allow him to get cold or chilled after the bath. Bathing will reduce the amount of virus left on his fur and will help reduce contagion.

Resuming Vaccines

Your pet cannot be re-infected with this virus for at least 3 years and is probably protected for life after surviving infection. However, it is imperative that he still receives vaccinations as there are other viruses that he should be protected against.

Your pet should lead a normal life once the recovery period is completed (1-2 weeks). In rare cases, there may be lasting effects on the heart.

Disinfecting the Environment

Canine parvovirus is especially hardy in the environment and particularly difficult to remove. It is readily carried on shoes or clothing to new areas (which accounts for its rapid worldwide spread shortly after its original appearance). It is able to overwinter freezing temperatures in the ground outdoors, plus many household disinfectants are not capable of killing it indoors.

• Infected dogs shed virus (in their stool) in gigantic amounts during the 7 to 10 days following exposure. Because such enormous amounts of virus are shed, there is a HUGE potential for environmental contamination when an infected dog has been there.
• It is important to realize that because the canine parvovirus is so hardy in the environment, it is considered ubiquitous. This means that no environment is free from this virus unless it is regularly disinfected.
• A parvoviral infection can be picked up anywhere, although it is easier to pick up an infection in an area where an infected dog has been simply because of the larger amounts of virus in a contaminated area.
• Whether an individual dog gets infected or not depends on the number of viral particles the dog experiences, what kind of immune experience the dog has had with the virus before (vaccinated? previously infected? How much past exposure?), and how strong the individual dog is (stress factors, diet, etc.)

A typical/average infectious dose for an unvaccinated dog is 1,000 viral particles. For some dogs far less is needed. For other dogs, far more is needed. An infected dog sheds 35 million viral particles (35,000 TIMES the typical infectious dose) per OUNCE of stool.

Environmental Decontamination

Parvovirus is virtually impossible to completely remove from an environment. The goal of decontamination is to reduce the number of viral particles to an acceptable level. There are many cleaners on the market with claims to eliminate parvovirus. However, realistically it is virtually impossible to remove parvovirus from an environment.

Bleach: One of the best and most effective disinfectants against parvovirus is BLEACH. However, it important to note that bleach is inactivated in the presence of organic material such as feces, vomitus or other bodily fluids. Therefore, all surfaces and items must first be cleaned with a detergent or other household cleaner. Then, mix one part bleach with 30 parts water. This solution is then applied to bowls, floors, surfaces, toys, bedding, and anything contaminated that is colorfast or for which color changes are not important. The bleach solution must be allowed to soak on the surfaces and items for at least 10 minutes to be effective at killing the virus. Disinfection becomes problematic for non-bleachable surfaces such as carpet or lawn.

Steam Cleaning: Steam is also able to kill the virus.

Rescue® (accelerated hydrogen peroxide cleaner): This is a virucidal agent that we use in our hospital. It is safe on all surfaces and effective as a detergent and disinfectant. Gallons of this cleaner can be purchased if you prefer this over bleach.

Indoor Decontamination

Indoors, where normal room temperature is maintained, the virus loses its infectivity within one month. Therefore, it should be safe to introduce a new puppy indoors one month after the active infection has ended.

Outdoor Decontamination

Freezing does NOT kill the virus. If the outdoors is contaminated and is frozen, you must wait for it to thaw out and warm up before safely introducing a new puppy. Shaded areas should be considered contaminated for seven months. Areas with good sunlight exposure should be considered contaminated for five months.

If you have any questions about your pet’s care after discharge from the hospital, please feel free to contact our office.

Canine Lyme Disease

Lyme disease is an emerging infectious disease at Allegheny Veterinary Service and within our practice area. As a result, we are constantly updating our diagnostic and treatment protocols. We now test all canine patients during their annual wellness exam and sick patients that present with lameness and fever when no other obvious cause is found. In addition, vaccination against Lyme disease is recommended as a core vaccine for all canine patients.

What Is Lyme Disease?

Lyme disease is the most common tick-borne disease in the United States. The disease was first identified in Lyme, Connecticut, in the 1980s. Human and canine cases remained primarily concentrated in the northeastern United States for many years. From 2005 to 2015, our practice diagnosed 2-3 cases per year. More recently Lyme disease has migrated into our area of West Virginia. In our practice, we have noted a sharp increase in cases since 2015. As of 2020, it is common in our practice to diagnose one Lyme-positive case each day. Overall, 25% of the dogs tested at our practice are positive for Lyme disease.

How Do Dogs Get Lyme Disease?

Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi, and transmitted by an Ixodes tick bite after 2-3 days of tick attachment. These “deer ticks” live in outdoor greenery and feed on birds, mice, small mammals, deer, dogs, people, etc. Migrating birds bring infected ticks to new habitats. Lyme disease is not contagious between infected animals and people without a tick bite. An individual tick only feeds on one host each season. Nymphal ticks are mostly active in the spring; adult ticks are active in the fall.

How Will I Know if My Dog Has Lyme Disease?

Sometimes dogs show illness, such as eye problems or lameness, due to Lyme disease. Based on experimental studies, young puppies (6-12 weeks old) appear to be more sensitive, with a self-limiting illness consisting of 4 days of fever and decreased appetite, with limping occurring 2-5 months after the tick bite. Older puppies (13-26 weeks old) have a shorter, 2-day illness, and adult dogs show none of these clinical signs (“symptoms”) in an experimental setting.

How Do We Test for Lyme Disease?

Our hospital performs a screening test for Lyme disease (along with heartworm and other tick-borne diseases) on all dogs at the annual exam. In addition, dogs are often tested when presenting sick with fever from an unidentified source, lameness, or kidney disease. This test is a quick screening test performed with a small blood sample.

What if My Dog Is Positive on a Screening Test?

A positive result indicates that a patient has been exposed to Borrelia burgdorferi, the bacteria that causes Lyme disease. Not all animals that get exposed (test positive) will become sick. Up to 70% of positive cases may just be exposed and suffer no further problems. However, 5% of the cases that test positive can develop serious complications with potentially deadly consequences, such as “Lyme nephritis.”

What Further Tests Can Be Performed to Make Sure That My Dog Does Not Have Lyme Disease?

If your dog is positive for Lyme disease on our screening test during an annual exam: Our veterinarians will recommend checking a urine sample to determine whether there is kidney disease. In addition, our veterinarians may recommend a further blood test to estimate the level of infection.

What Is Lyme Nephritis?

“Lyme nephritis” is a rare but severe form of kidney damage that has been associated with Lyme disease in dogs. This appears more common in Labrador and golden retrievers. The earliest warning of Lyme nephritis is protein in the urine (proteinuria). ALL Lyme-positive dogs should be screened and monitored through urine samples over time for proteinuria, even if previously treated for Lyme disease, since treatment may not prevent the development of Lyme nephritis.

How Can I Prevent Lyme Disease In My Dog?

Vaccination: Due to the increasing risk and incidence of this disease in our area, we now recommend Lyme vaccination for ALL canine patients as part of the annual examination. This vaccination has very low risk and reactions are rare.

Canine Hyperadrenocorticism (Cushing’s Disease)

What Causes Cushing’s Disease?

Cushing’s disease, or hyperadrenocorticism, is caused by an excess of stress hormone (cortisol) from the adrenal glands. This excess can be caused by overproduction of cortisol by the adrenal glands, abnormal signaling from brain to the adrenal glands or long-term steroid usage (such as prednisone, prednisolone, Temaril P, or dexamethasone). This extra stress hormone can cause several symptoms, leading to trouble regulating blood sugar, immune-mediated problems, weak bones and cartilage, liver problems, and problems with metabolism of essential nutrients. Permanent damage to organs may occur if the disease is left untreated.

What Age & Breeds Are Typically Affected?

Although Cushing’s disease can occur in any breed, poodle breeds, dachshunds, terriers, German shepherds, beagles, and Labrador retrievers are most commonly affected. Dogs with Cushing’s disease are typically older than six, with an average age of 10 years old.

How Will I Know if My Dog Is Showing Signs?

Signs of Cushing’s disease can be non-specific, and are often confused with normal aging, making this disease tricky to recognize.

Common Signs:

-increased drinking
-frequent urination or accidents in the house
-“pot-bellied” or enlarged abdomen
-hair loss
-muscle wasting or loss of muscle tone

Other Signs:

-recurrent skin infections
-urinary tract infections
-hypertension / high blood pressure
-diabetes (especially those that are hard to regulate)
-bilateral cranial cruciate disease

How Can We Test My Dog for Cushing’s Disease?

Cushing’s disease can be very tricky to diagnose. Diagnosis starts with a thorough history of your dog’s health and general physical examination. Often, there are changes on basic bloodwork, such as elevated liver enzymes, that indicate possible Cushing’s disease. A complete urine exam may also be performed as Cushing’s disease often causes recurrent urinary tract infections. Abdominal x-rays or ultrasound may be needed to evaluate the health and structure of your dog’s liver and rule out other disease.

If results of these basic tests raise suspicion, we will recommend additional testing to specifically identify Cushing’s disease. Each test for Cushing’s disease has advantages and disadvantages.

Urine Cortisol / Creatinine Ratio: This test is convenient because you collect the pet’s urine at home and deliver it to the clinic for processing. The first morning urine should be collected each morning for three days in a row. The samples may be combined into one container and must be refrigerated until delivery to the clinic. Sample collection should be delayed at least six days after a visit to the veterinarian or groomer. Negative results from this test indicate that the Cushing’s disease is very unlikely. However, positive results must be confirmed with a specific blood test.

Low-Dose Dexamethasone Test: This test requires the patient to be fasted (held off of food) and stay at the clinic for the day. Three blood samples are drawn throughout the day over an eight-hour period. This test is the most sensitive test available to diagnose Cushing’s disease.

ACTH Stimulation Test: This test must be used when a patient has been receiving steroids for treatment of other disease. It is also used for monitoring treatment levels in pets currently receiving treatment for Cushing’s disease. This test requires the patient to remain at the clinic for a half day for two to three blood samples over several hours. Patients should be fasted for this test. When using this test for monitoring of treatment, Vetoryl® (trilostane) should be administered 4-6 hours prior to testing.

Unfortunately, there is no perfect test for Cushing’s disease and all of these diagnostic tests can have confusing results. For this reason, many testing trials may be required to reach a conclusion or confirm a diagnosis. This can be frustrating, but it is important to remain persistent and patient as we work through this diagnosis.

How Is Cushing’s Disease Treated?

Medical and surgical methods are used to treat Cushing’s disease. Surgical treatment involves removal of the adrenal glands and may “cure” disease but is risky to perform. Medical treatment is usually preferred and will alleviate your pet’s symptoms. Medical treatment for Cushing’s disease is lifelong. Supportive care for liver disease is often recommended.

Vetoryl® (trilostane): Trilostane is the only FDA-approved medication for treatment of all types of Cushing’s in dogs. This medication may be given once or twice daily depending on the individual. An ACTH Stimulation test will be conducted two weeks after starting this medication or two weeks after any dose change. Side effects: weakness, collapse, lethargy, decreased appetite, diarrhea and vomiting. Should any of these side effects occur, please notify our office as soon as possible.

Lysodren® (mitotane): Mitotane may be used as an alternative treatment and should be discussed on a case-by-case basis.

Liver Supplements: Supplements such as S-Adenosyl-L-Methionine (SAMe) and adenosine may be recommended to support general liver health.

My Dog Has Been Diagnosed With Cushing’s! What Now?

Although lifespan is generally shortened by 2.5-5 years, dogs with Cushing’s disease may live for many years with appropriate treatment. Lifespan is also affected by concurrent disease, age at the time of diagnosis and treatment compliance.

ACTH Stimulation Tests: Monitoring of appropriate medication levels is important as serious side effects and even death may occur. An ACTH stimulation test should be conducted every six to twelve months. Some patients may require testing every three months to ensure appropriate control of the disease.

Blood Pressure: Blood pressure should be checked during regular examinations to detect hypertension.

Keep a Journal: Note changes in your dog’s habits, particularly urination and weight gain or loss. In addition, note any recurrence of clinical signs and the appearance of possible side effects.

Veterinary Visits: Semi-annual physical examinations are important to detect other problems such as skin infections, ear infections and urinary tract infections.

Pig Health

As the owner, it is ultimately your responsibility to provide a healthy environment so that your pig may flourish and grow. A keen understanding of good husbandry practices, basic infectious disease prevention, swine diseases and conditions specific to your pig and your farm are critical to the success of your project. This document is only meant to be a starting point for your farm health plan. You should also establish a relationship with a veterinarian to assist with a protocol specific to your farm.

FDA Restrictions

Off-Label use of antibiotics, dewormers and other treatments is strictly prohibited in food animals. These rules are set in place to protect the consumer and our food supply. Be sure to check all medication labels and comply with labeled use, dose and withdrawal times.


Our doctors commonly diagnose sarcoptic mange, demodectic mange and intestinal parasites in pigs. We recommend treating pigs with ivermectin 1% at 1 cc per 75 lbs subcutaneously. Fecals may be examined to determine if other dewormers are needed.


Vaccines are available for over 25 diseases in swine. Most swine vaccines are only available in large herd-size quantities, such as a 250-dose bottle. Ideally, pigs should be vaccinated by the breeder and prior to purchase or moving. It is critical that you discuss specific risks and needs with your veterinarian to customize a vaccination protocol for your farm.

At a minimum, all show pigs should be vaccinated for:

Erysipelothrix rhusiopathiae (Diamond Skin Disease) – A killed bacterin is recommended. Initial dose at 8 to 12 weeks of age. Booster 4 weeks after initial dose. This should be boostered 6 weeks prior to the fair.

Swine Influenza (H1N1, H1N2, H3N2) – Initial dose at 6 weeks of age. Booster 3 weeks after the initial dose. Do not vaccinate for 21 days prior to slaughter.

Benefits of Omega-3 Fatty Acids in the Equine Diet

What Are Omega-3 Fatty Acids?
Omega-3 fatty acids are compounds found in our diets that are very beneficial as natural ANTI-inflammatories. Omega-3 fatty acids have been shown to reduce inflammation and support immune function. We often recommend them as adjunct therapy for many conditions including:

  • Inhalant Allergies (Heaves, RAO, Equine Asthma);
  • Skin Allergies (Sweet Itch, Culicoides Hypersensitivity);
  • Other Skin Conditions (Dry Skin);
  • Respiratory Issues;
  • Arthritis and Joint Pain;
  • Reproductive Issues – Omega 3s improve fertility, and increase sperm concentration, motility and viability.; and
  • enriching colostrum quality and improving colostral antibody absorption in foals.

Are All Omega-3 Fatty Acids the same?
No. Of the omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have the most efficient biologic activity and therefore, are the most beneficial. As a result, we recommend sources that are specifically high in these types of omega-3 fatty acids.

What Are the Best Sources of DHA and EPA?
The best sources of DHA and EPA omega-3 fatty acids are fish oil, safflower and sunflower oil. This poses a challenge for horse owners because fish oil is not very palatable to our equine companions.

What Are Omega-6 Fatty Acids?
Omega-6 fatty acids are commonly found in the same sources that have omega-3 fatty acids. Omega-6 fatty acids are, however, PRO-inflammatory. Therefore, our goal is to find a source with high omega-3 fatty acids and low omega-6 fatty acids. Unfortunately, many ingredients commonly used in equine diets are low in omega-3 fatty acids and higher in omega-6 fatty acids. These include cereal grains such as oats, corn and many vegetable oils.

Where Do Flaxseed and Flaxseed Oil Fit in?
Flaxseed oil has alpha-linolenic acid in it that is converted to DHA and EPA by the body; however, it is unknown how efficiently this conversion occurs. Therefore, flaxseed and flaxseed oils are a reasonable choice, but may not be as effective as some other sources.

So, Now I Am Confused. What Do I Feed My Horse?

  • Feed your horse good quality hay and pasture. Although low in total fat content, hay and pasture have a high omega-3 to omega-6 ratio.
  • When feeding fats for weight gain, feed flaxseed oil or flaxseed. Avoid corn oil.
  • When feeding omega-3 for anti-inflammatory effects, we recommend EO-3™ from Kentucky Equine Research. However, there are several other brands on the market as well.

Are There Any Side Effects to Feeding Omega-3 Fatty Acids?
With increasing amounts of fat in the diet, some horses may develop soft stool. This is unlikely to occur when feeding fat for anti-inflammatory effects but may occur when feeding larger amounts for weight gain.
