Caring for Your Faithful Companion

Parson Russell Terriers: What a Unique Breed!

Your dog is special! She’s your best friend, companion, and a source of unconditional love. Chances are that you chose her because you like PRTs and you expected her to have certain traits that would fit your lifestyle:

  • Highly intelligent, playful, and energetic
  • Alert, curious, and busy
  • Protective; an excellent guard dog
  • Bold, steady, and fearless
  • Bouncy, cheerful, loyal, and enthusiastic
  • Quirky, entertaining personality

However, no dog is perfect! You may have also noticed these characteristics:

  • Requires vigorous, frequent exercise and space to run
  • Can be rambunctious and rowdy, especially as a younger dog
  • Must be properly socialized with humans and other animals
  • Territorial with larger dogs, especially of the same sex
  • Prone to boredom and separation anxiety when left alone and will find trouble
  • Willful and stubborn if you don’t show strong leadership

Is it all worth it? Of course! She’s full of personality, and you love her for it! She is highly intelligent and needs a strong leader. With sufficient exercise and socialization, she makes an affectionate and lively family companion.

The Parson Russell Terrier was developed in England in the 1800’s and was bred for fox hunting and vermin control. The PRT is a small, tenacious terrier that is courageous and clever. Parson Russell Terriers are excellent escape artists that can climb, jump, or dig under fences. They have a high prey drive and will chase small animals. They are typical hunting terriers that love barking and digging. The Parson Russell Terrier is amusing and friendly: a great companion for an active family.

Your Parson Russell Terrier’s Health

We know that because you care so much about your dog, you want to take good care of her. That is why we have summarized the health concerns we will be discussing with you over the life of your Parson. By knowing about health concerns specific to Parson Russell Terriers, we can tailor a preventive health plan to watch for and hopefully prevent some predictable risks.

Many diseases and health conditions are genetic, meaning they are related to your pet’s breed. There is a general consensus among canine genetic researchers and veterinary practitioners that the conditions we’ve described herein have a significant rate of incidence and/or impact in this breed. That does not mean your dog will have these problems; it just means that she is more at risk than other dogs. We will describe the most common issues seen in Parson Russell Terriers to give you an idea of what may come up in her future. Of course, we can’t cover every possibility here, so always check with us if you notice any unusual signs or symptoms.

This guide contains general health information important to all canines as well as the most important genetic predispositions for Parson Russell Terriers. This information helps you and us together plan for your pet’s unique medical needs. At the end of the booklet, we have also included a description of what you can do at home to keep your PRT looking and feeling her best. You will know what to watch for, and we will all feel better knowing that we’re taking the best possible care of your pal.

General Health Information for your Parson Russell Terrier

Dental Disease

Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. And unfortunately, your Parson is more likely than other dogs to have problems with her teeth. It starts with tartar build-up on the teeth and progresses to infection of the gums and roots of the teeth. If we don’t prevent or treat dental disease, your buddy will lose her teeth and be in danger of damaging her kidneys, liver, heart, and joints. In fact, your Parson’s life span may be cut short by one to three years! We’ll clean your dog’s teeth regularly and let you know what you can do at home to keep those pearly whites clean.

Infections

Parson Russell Terriers are susceptible to bacterial and viral infections — the same ones that all dogs can get — such as parvo, rabies, and distemper. Many of these infections are preventable through vaccination, which we will recommend based on the diseases we see in our area, her age, and other factors.

Obesity

Obesity can be a significant health problem in Parson Russell Terriers. It is a serious disease that may cause or worsen joint problems, metabolic and digestive disorders, back pain and heart disease. Though it’s tempting to give your pal food when she looks at you with those soulful eyes, you can “love her to death” with leftover people food and doggie treats. Instead, give her a hug, brush her fur or teeth, play a game with her, or perhaps take her for a walk. She’ll feel better, and so will you!

Parasites

All kinds of worms and bugs can invade your PRT’s body, inside and out. Everything from fleas and ticks to ear mites can infest her skin and ears. Hookworms, roundworms, heartworms, and whipworms can get into her system in a number of ways: drinking unclean water, walking on contaminated soil, or being bitten by an infected mosquito. Some of these parasites can be transmitted to you or a family member and are a serious concern for everyone. For your canine friend, these parasites can cause pain, discomfort, and even death, so it’s important that we test for them on a regular basis. We’ll also recommend preventive medication as necessary to keep her healthy.

Spay or Neuter

One of the best things you can do for your Parson is to have her spayed (neutered for males). In females, this means we surgically remove the ovaries and usually the uterus, and in males, it means we surgically remove the testicles. Spaying or neutering decreases the likelihood of certain types of cancers and eliminates the possibility of your pet becoming pregnant or fathering unwanted puppies. Performing this surgery also gives us a chance, while your pet is under anesthesia, to identify and address some of the diseases your dog is likely to develop. For example, if your pet needs hip X-rays or a puppy tooth extracted, this would be a good time. This is convenient for you and easy for your friend. Routine blood testing prior to surgery also helps us to identify and take precautions for common problems that increase anesthetic or surgical risk. Don’t worry; we’ll discuss the specific problems we will be looking for when the time arrives.

Genetic Predispositions for Parson Russell Terriers

Eye Problems

Not many things have as dramatic an impact on your dog’s quality of life as the proper functioning of his eyes. Unfortunately, Parson Russell Terriers can inherit or develop a number of different eye conditions, some of which may cause blindness if not treated right away, and most of which can be extremely painful! We will evaluate his eyes at every examination to look for any signs of concern.

Primary Lens Luxation (PLL) is an inherited disease, common in PRTs, that causes the tiny fibers that hold the lens suspended within the eye to degrade and break. When this happens, the lens drops out of place. If it happens to fall forward, it can block the normal circulation in the eye and cause secondary glaucoma. Surgery to remove the loose lens may be needed to relieve pain.

Glaucoma, an eye condition that affects Parson Russell Terriers and people too, is an extremely painful disease that rapidly leads to blindness if left untreated. Symptoms include squinting, watery eyes, bluing of the cornea (the clear front part of the eye), and redness in the whites of the eyes. Pain is rarely noticed by pet owners though it is frequently there and can be severe. People who have certain types of glaucoma often report it feels like being stabbed in the eye with an ice pick! Yikes! In advanced cases, the eye may look enlarged or swollen like it’s bulging. We’ll perform his annual glaucoma screening to diagnose and start treatment as early as possible. Glaucoma is a medical emergency. If you see symptoms, don’t wait to call us, go to an emergency clinic!

Cataract

Cataract

Cataracts are a common cause of blindness in older Parsons. We’ll watch for the lenses of his eyes to become more opaque—meaning they look cloudy instead of clear—when we examine him. Many dogs adjust well to losing their vision and get along just fine. Surgery to remove cataracts and restore sight may also be an option.

Liver Problems

Your PRT is more likely than other dogs to have a liver disorder called portosystemic shunt (PSS). Some of the blood supply that should go to the liver goes around it instead, depriving the liver of the blood flow it needs to grow and function properly. If your friend has PSS, his liver cannot remove toxins from his bloodstream effectively. To check for this problem, we’ll conduct a liver function test in addition to a standard pre-anesthetic panel every time he undergoes anesthesia. If he develops symptoms such as stunted growth or seizures, we’ll test his blood and possibly conduct an ultrasound scan of his liver. Surgery may be needed, but in some cases, we can treat with a special diet and medication.

Hemolytic Anemia and Thrombocytopenia

Parsons are particularly prone to some relatively rare diseases of the blood. They occur when the immune system goes haywire and starts attacking the pet’s own red blood cells or platelets. If the immune system destroys red blood cells, your dog quickly becomes anemic, weak, and lethargic. His gums will look whitish or yellow instead of the normal bright pink color. If the immune system destroys platelets, his blood won’t clot properly and he’ll have bruises or abnormal bleeding. We’ll perform diagnostic testing for blood clotting to check for these problems before we perform any surgeries. To slow or stop the immune system’s destruction of cells, we’ll prescribe steroids and other immune-suppressive drugs. Sometimes an emergency transfusion of red blood cells or platelets is needed.

Bladder or Kidney Stones

There are a few different types of stones that can form in the kidney or in the bladder, and Parson Russell Terriers are more likely to develop them than other breeds. We’ll periodically test his urine for telltale signs indicating the presence of kidney and bladder stones; they are painful! If your buddy has blood in his urine, can’t urinate, or is straining to urinate, it is a medical emergency. Call us immediately!

Hip and Elbow Dysplasia

Both hips and elbows are at risk for dysplasia, an inherited disease that causes the joints to develop improperly and results in arthritis. Stiffness in your Parson’s elbows or hips may become a problem for him, especially as he matures. You may notice that he begins to show lameness in his legs or has difficulty getting up from lying down. We can treat the arthritis—the sooner the better—to minimize discomfort and pain. We’ll take X-rays of your dog’s bones to identify issues as early as possible. Surgery is sometimes a good option in severe and life-limiting cases. Keep in mind that overweight dogs may develop arthritis years earlier than those of normal weight, causing undue pain and suffering!

Young Parson Russell Terriers may be prone to a painful degenerative hip condition called Legg-Calve-Perthes Disease. The exact cause of this condition is still not completely understood, but it is thought to be a problem with blood supply to the hip, which causes the femoral head (the top of the thigh bone) to become brittle and easily fracture. Ouch! Usually occurring between six and nine months of age, it causes pain and lameness in one or both rear legs, and often requires surgery.

Knee Problems

Sometimes your Parson’s kneecap (patella) may slip out of place (called patellar luxation). You might notice that he runs along and suddenly picks up a back leg and skips or hops for a few strides. Then he kicks his leg out sideways to pop the kneecap back in place, and he’s fine again. If the problem is mild and involves only one leg, your friend may not require much treatment beyond arthritis medication. When symptoms are severe, surgery may be needed to realign the kneecap to keep it from popping out of place.

Allergies

In humans, an allergy to pollen, mold, or dust makes people sneeze and their eyes itch. In dogs, rather than sneeze, allergies make their skin itchy. We call this skin allergy “atopy”, and Parsons often have it. Commonly, the feet, belly, folds of the skin, and ears are most affected. Symptoms typically start between the ages of one and three and can get worse every year. Licking the paws, rubbing the face, and frequent ear infections are the most common signs. The good news is that there are many treatment options available for this condition.

Neurologic Problems

Several neurologic diseases can afflict Parson Russell Terriers. Symptoms of neurological problems can include seizures, imbalance, tremors, weakness, or excess sleeping. If you notice any of these symptoms, please seek immediate veterinary care.

Epilepsy

There are three types of seizures in dogs: reactive, secondary, and primary. Reactive seizures are caused by the brain’s reaction to a metabolic problem like low blood sugar, organ failure, or a toxin. Secondary seizures are the result of a brain tumor, stroke, or trauma. If no other cause can be found, the disease is called primary, or idiopathic epilepsy. This problem is often an inherited condition, with Parson Russell Terriers commonly afflicted. If your friend is prone to seizures, they will usually begin between six months and three years of age. An initial diagnostic workup may help find the cause. Lifelong medication is usually necessary to help keep seizures under control, with periodic blood testing required to monitor side effects and effectiveness. If your dog has a seizure: Carefully prevent him from injuring himself, but don’t try to control his mouth or tongue. It won’t help him, and he may bite you accidentally! Note the length of the seizure, and call us or an emergency hospital.

Dental Abnormalities

Teeth abnormalities are often genetically induced and are relatively common in dogs, especially in purebred dogs like your Parson. An overbite or underbite is called a malocclusion, or a bad bite. Oligodontia is a condition where only a few teeth are present. Misaligned teeth can also occur and cause lots of problems, but can usually be corrected with braces or extractions. (Yes, dogs can get braces!) We want to keep your buddy’s teeth healthy so we will be watching his developing teeth closely.

heartNormalInsidesHeart Disease

Some Parson Russell Terriers inherit a heart condition known as pulmonic stenosis. This disease causes a partial obstruction of blood flow from the heart to the lungs, which means the heart must work harder to pump enough blood. If the condition is severe enough, your dog may faint or just seem to run out of energy during exercise. He may also have difficulty breathing, cough, or not grow as much as he should. We’ll test for this disease during your dog’s life and discuss treatment options with you if he has the condition. Surgery is an option when symptoms are severe.

Skin Infections

Your PRT is susceptible to different kinds of skin infections and diseases. One of them is caused by yeast (Malassezia dermatitis). When it infects the ears, it causes itching, redness, and brown waxy discharge. On the skin, it leads to greasy, hairless areas, especially on the neck and throat, with a characteristic odor. Underlying causes such as allergies together with this infection increase his itchiness and discomfort. The earlier you call to have skin problems checked out, the less likely it is that you will end up caring for an itchy, bald, smelly dog. You don’t want that, and neither does he!

Ichthyosis

Dry, flaky, itchy skin is a common problem for many dogs, but PRTs in particular are prone to a severe flaking skin condition called ichthyosis. Named for the large dry flakes that resemble fish scales, this problem usually arises very early in life, with most affected puppies born with abnormal skin. Several palliative treatment options like special shampoos and fish oils give variable levels of relief, but there is no definitive cure for this inherited disease. There is a genetic test available for many breeds that can determine whether he is clear, a carrier, or affected. This is important information if you are planning to use your friend for breeding, as it is not recommended to breed dogs who are affected or carriers; the goal is to prevent this debilitating disease in future generations.

Pattern Baldness

The medical term for pattern baldness is Follicular Dysplasia, and just like in people, it is a heritable condition. You may notice that the fur on your Parson Russell Terrier’s neck or rear legs is starting to look sparse or patchy, with hairs that break off easily and don’t grow back readily. Like baldness in humans, the condition is not painful and causes no harm, but currently there is no effective treatment or prevention. A fashionable sweater can help on cold days.

Deafness

Heritable deafness has been noted in some PRT bloodlines, so if his ears are healthy and he’s still ignoring you, a more thorough hearing workup may be needed, including brainwave analysis, if indicated. If you suspect he may not be hearing as well as he should, schedule an appointment with us right away as the problem could also be caused by a severe ear infection.

Tail Chasing

Lots of dogs enjoy a healthy game of “chase the tail.” However, for some Parson Russell Terriers, this can become a repetitive, compulsive neurologic disorder similar in some ways to a seizure, during which the dog may actually injure himself. If your friend appears to be a bit too interested in his tail, try to distract him with another game, and don’t encourage the behavior. If we catch it early, we may be able to prevent problems with special behavior training. Various medications may also be needed. In some severe cases, the problem may be extremely difficult to control.

ParsonRusselTerrier1of2Taking Care of Your Parson Russell Terrier at Home

Much of what you can do to keep your dog happy and healthy is common sense, just like it is for people. Watch her diet, make sure she gets plenty of exercise, regularly brush her teeth and coat, and call us or a pet emergency hospital when something seems unusual (see “What to Watch For” below). Be sure to adhere to the schedule of examinations and vaccinations that we recommend for her. This is when we’ll give her the necessary “check-ups” and test for diseases and conditions that are common in Parsons. Another very important step in caring for your pet is signing up for pet health insurance. There will certainly be medical tests and procedures she will need throughout her life and pet health insurance will help you cover those costs.

Routine Care, Diet, and Exercise

Build her routine care into your schedule to help your PRT live longer, stay healthier, and be happier during her lifetime. We cannot overemphasize the importance of a proper diet and exercise routine.

  • Supervise your pet as you would a toddler. Keep doors closed, pick up after yourself, and block off rooms as necessary. This will keep her out of trouble and away from objects she shouldn’t put in her mouth.
  • Brush her coat as needed, at least weekly.
  • Parson Russell Terriers generally have good teeth, and you can keep them perfect by brushing them at least twice a week!
  • Clean her ears weekly, even as a puppy. Don’t worry—we’ll show you how!
  • She’s a smart dog with lots of energy, so keep her mind and body active, or she’ll get bored. That’s when the naughty stuff starts.
  • A tall fence in a must, PRTs have been known to jump great heights. She also can’t resist chasing cats, so keep her on a leash outdoors.
  • She is an athletic dog that excels at dog sports like flyball and agility.
  • Keep your dog’s diet consistent and don’t give her people food.
  • Feed a high-quality diet appropriate for her age.
  • Exercise your dog regularly, but don’t overdo it at first.

What to Watch For

Any abnormal symptom could be a sign of serious disease, or it could just be a minor or temporary problem. The important thing is to be able to tell when to seek veterinary help, and how urgently. Many diseases cause dogs to have a characteristic combination of symptoms, which together can be a clear signal that your Parson Russell Terrier needs help.

Office calls

Give us a call for an appointment if you notice any of these types of signs:

  • Change in appetite or water consumption
  • Tartar build-up, bad breath, red gums, or broken teeth
  • Itchy skin (scratching, chewing, or licking), hair loss
  • Lethargy, mental dullness, or excessive sleeping
  • Fearfulness, aggression, or other behavioral changes

Emergencies

Seek medical care immediately if you notice any of these types of signs:

  • Scratching or shaking the head, tender ears, or ear discharge
  • Inability or straining to urinate; discolored urine
  • Cloudiness, redness, itching, or any other abnormality involving the eyes
  • Slow or stunted growth; sometimes seizures after eating
  • Gums that are a color other than bright pink
  • General reluctance to run or play
  • Any abnormal shaking, trembling, or excessive involuntary tremors
  • Easily startled, no reaction to unseen sounds
  • Repetitive, compulsive whirling
  • Leg stiffness, reluctance to rise, sit, use stairs, run, jump, or “bunny hopping”

Partners in Health Care

DNA testing is a rapidly advancing field with new tests constantly emerging to help in the diagnosis of inherited diseases before they can become a problem for your friend. For the most up-to-date information on DNA and other screening tests available for your pal, visit www.Genesis4Pets.com.

Your Parson counts on you to take good care of her, and we look forward to working with you to ensure that she lives a long and healthy life. Our goal is to provide the best health care possible: health care that’s based on her breed, lifestyle, and age. Please contact us when you have questions or concerns.
