Caring for Your Faithful Companion

Manchester 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 Manchesters and you expected her to have certain traits that would fit your lifestyle:

  • Lively, with a friendly personality
  • Alert, curious, and busy
  • Adaptable to a wide variety of living conditions
  • Energetic and playful
  • Excellent watchdog
  • People-oriented and eager to please

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

  • May have a tendency to bark excessively
  • Needs regular exercise and diet regulation to avoid weight gain
  • Likely to attack other small animals, including cats
  • Prone to boredom and separation anxiety when left alone and will find trouble
  • Can be snappy when nervous
  • Can be possessive of toys and food, tending to show dominance

Is it all worth it? Of course! She’s full of personality, and you love her for it! She enjoys human contact and demands to be included in all family activities. A constant human companion that rewards her family with affection, loyalty, and protection.

The Manchester Terrier originated in England and was bred to control rat populations. Manchesters come in two varieties: the standard and the toy. This is a high-spirited little dog that is intelligent and entertaining. The Manchester Terrier is described as a tidy dog that takes care of its own grooming and has little odor. Manchester Terriers form strong bonds with their family and make excellent watchdogs, which means you’ll have to socialize them for strange people and dogs to prevent agression.

Your Manchester 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 Manchester. By knowing about health concerns specific to Manchester 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 Manchester 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 Manchester 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 Manchester 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 Manchester Terrier

Dental Disease

Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. And unfortunately, your Manchester 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 Manchester’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.


Manchester 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 can be a significant health problem in Manchester 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!

All kinds of worms and bugs can invade your Manchester’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 Manchester 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 Manchester 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, Manchester 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.



Cataracts are a common cause of blindness in older Manchesters. 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.

Primary Lens Luxation (PLL) is an inherited disease, common in Manchesters, 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.

Progressive Retinal Atrophy (PRA) is an inherited disease in which the eyes are genetically programmed to go blind. Unfortunately, Manchester Terriers are a bit more likely than other dogs to have this condition. PRA is not painful, but also not curable. In dogs with the bad gene, early symptoms such as night blindness or dilated pupils generally begin around three to five years of age. A genetic test is available for this condition.

Bleeding Disorders

There are several types of inherited bleeding disorders which occur in dogs. They range in severity from very mild to very severe. Many times a pet seems normal until a serious injury occurs or surgery is performed, and then severe bleeding can result. Von Willebrand’s disease is a blood clotting disorder frequently found in Manchester Terriers. We’ll conduct diagnostic testing for blood clotting time or a specific DNA blood test for Von Willebrand’s disease or other similar disorders to check for this problem before we perform surgery.

Hip Necrosis

Young Manchester 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 Manchester’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.


Diabetes mellitus is a fairly common disease in dogs. Any breed can be affected, but Manchesters have an above average incidence. Dogs with diabetes are unable to regulate the metabolism of sugars and require daily insulin injections. It is a serious condition and one that is important to diagnose and treat as early as possible. Symptoms include increased eating, drinking, and urination, along with weight loss. If he shows signs, we will conduct lab tests to determine if he has this condition and discuss treatment options with you. Treatment requires a serious commitment of time and resources. Well regulated diabetic dogs today have the same life expectancy as other canines.

Heart Disease

Manchester Terriers are especially prone to a life-threatening heart condition known as dilated cardiomyopathy, or DCM, in which the heart becomes so large, thin, and weak that it can no longer effectively pump blood to the body. As this problem advances, he may act weak or tired, faint or collapse, breathe in a labored way, or cough. We’ll conduct a yearly electrical heart screening(ECG) and/or an echocardiogram starting at age one to look for abnormal heart rhythms early. If found, we’ll treat this condition with medication and may also recommend dietary supplementation.

Retained Puppy Teeth

Dogs normally begin to lose their primary (“puppy”) teeth at around 4 months of age. When the primary teeth don’t fall out as the adult teeth come in, infection or damage to the adult teeth may develop. Retained teeth are common in small breeds like Manchesters. The retained puppy teeth trap food and hair between the normal adult tooth and the primary tooth. Painful gums, bad breath and adult tooth loss can result if untreated. We’ll monitor his growing teeth and recommend removal of the puppy teeth if they are present alongside his adult teeth.

Inflammatory Bowel Disease

Inflammatory Bowel Disease or IBD is an immune system disorder common in Manchesters in which the intestinal lining becomes overrun with immune system cells called lymphocytes and plasmacytes. The stomach and/or intestinal lining becomes thickened affecting his ability to absorb nutrients properly. Chronic vomiting or diarrhea is common or it may flare up suddenly and then improve again for a time. Stress, diet change, or intestinal parasites may make it worse. If your friend has diarrhea or digestive upsets that are not explained by the more common reasons, diagnostic tests, which may include intestinal biopsy, will be needed. Lifetime medications and special diets are usually required to keep this bellyache under control.


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 Manchesters 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.

Mast Cell Tumor

Mast cell tumors are a particularly nasty type of skin cancer found more often in Manchester Terriers, and the sooner they are surgically removed the better. Trouble is, they often look just like other kinds of skin lumps and lesions, some of which are harmful, and others not. All suspicious lumps should be tested and any questionable lump should be surgically removed as soon as possible. Many cancers are cured by surgically removing them, so early detection and removal is critical.


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 Manchester 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.

Water on the Brain

Hydrocephalus occurs when fluid builds up inside the skull and puts pressure on the brain. This condition is most common in breeds with dome-shaped heads, like your Manchester Terrier. It is often present when the skull bones don’t fuse properly. Signs include seizures, difficulty training the puppy, dulled mental function, circling, and a spastic gait. It is usually diagnosed early in life, but occasionally we diagnose it in adult dogs. We’ll keep this risk in mind during her visits and recommend early testing and discuss effective treatment options if symptoms develop.


Demodex is a microscopic mite that lives in the hair follicles of dogs. All dogs have them. Normally a dog’s immune system keeps the mites in check, but some breeds, like your Manchester, develop an overabundance of these mites. In mild cases, pet owners may notice a few dry, irritated, hairless lesions. These often occur on the face or feet and may or may not be itchy. Secondary skin infections may occur. Prompt veterinary care is important to keep the disease from getting out of hand. Many pets seem to outgrow the problem, while others require lifelong management.

Seasonal Hair Loss

Seasonal flank alopecia is a condition that causes a dog to lose his hair in patches usually on the sides just ahead of the rear legs, although other areas can be affected. It happens seasonally (often in fall or spring), and usually when the season changes the hair grows back. Not always, though, and sometimes the hair regrows a different color. It’s not yet understood why this happens, but it seems to happen more often in Manchester Terriers. Dietary supplements are sometimes effective for control of this otherwise harmless condition, so if it becomes a concern we’ll work out a dosing regimen and monitor for side effects.

Thyroid Problems

Manchesters are prone to a common condition called hypothyroidism in which the body doesn’t make enough thyroid hormone. Signs can include dry skin and coat, hair loss, susceptibility to other skin diseases, weight gain, fearfulness, aggression, or other behavioral changes. We’ll conduct a blood screening test annually to screen for the disease. Treatment is usually simple: replacement hormones given in the form of a pill.

Manchester Terriers are prone to this painful, long term condition in which one or more areas around the anus develop sores. Signs include straining or apparent pain when defecating, bleeding, constipation, licking of the area, or smelly discharge around the rectum. The condition can be difficult to treat, and requires lifelong medications, prescription food, and sometimes even surgery.

Taking Care of Your Manchester 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 Manchesters. 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 Manchester 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 at least weekly.
  • Manchester Terriers often have serious problems with their teeth, so you’ll need to brush them at least three times a week!
  • Clean her ears weekly, even as a puppy. Don’t worry—we’ll show you how!
  • She is well suited to apartment life as long as she is given daily walks and short play sessions.
  • She has a strong chase instinct, so she needs to be leash walked and a fenced yard is a must.
  • 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 Manchester Terrier needs help.
