Caring for Your Faithful Companion

American Staffordshire 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 AmStaffs and you expected her to have certain traits that would fit your lifestyle:

  • An affectionate companion and family dog
  • Has a short, easy-to-care-for coat
  • Protective of family: good watch dog
  • Compact – does well in small living quarters
  • Devoted, loyal, and protective
  • Intelligent, friendly, and easily won over

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

  • Needs regular exercise and diet regulation to avoid weight gain
  • Aggressive toward other animals
  • May need supervision around children
  • Sees cats and small animals as prey unless trained otherwise
  • Must be properly socialized as a puppy to avoid aggression as an adult
  • Likes to dig

Is it all worth it? Of course! She’s full of personality, and you love her for it! She is a protective and affectionate dog that needs a strong leader and daily exercise, as well as time to relax with her family.

The American Staffordshire Terrier originated from a cross between bulldogs and terriers and was initially bred for bull baiting and dog fighting. They were also commonly used for general farm work and hunting. AmStaffs are affable, smart, and protective of their family. They are a generally healthy breed with an average lifespan of 12 years. AmStaffs can suffer from common conditions like knee ligament tears and hypothyroidism. Early diagnosis is the key to a long and happy life, so be sure to schedule routine checkups.

Your American Staffordshire 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 Staffie. By knowing about health concerns specific to American Staffordshire 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 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 American Staffordshire 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 American Staffordshire 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 AmStaff 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 American Staffordshire Terrier

Dental Disease

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


American Staffordshire 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 American Staffordshire 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 AmStaff’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 Staffie 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 American Staffordshire Terriers

Knee Problems

Sometimes your Staffie’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.

Knee Ligament Tear

The cranial cruciate ligament is one of the four tough bands of tissue that hold each knee together. A torn cranial cruciate ligament is a common injury in active dogs, which includes your AmStaff. Usually surgical correction is done to stabilize the knee and help prevent crippling arthritis. Physical therapy and multimodal pain management are necessary to get the best outcome. Keeping him at the right weight, feeding a high-quality diet, and avoiding too much twisting of the knees (like playing Frisbee) are key in avoiding this painful injury.

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 Staffie’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!

Bone Pain

Growing Staffies can suffer from a painful inflammation of the long bones in the legs, a condition called eosinophilic panosteitis, pano or eo-pan. It usually starts at around six to ten months of age and shifts from leg to leg. We’ll look for this condition upon examination; if your pal exhibits pain when the area is squeezed or palpated, we’ll take X-rays to diagnose the problem. Panosteitis usually causes no permanent damage, but requires pain medication. If your dog has the condition and has developed an abnormal gait to compensate for the sore leg(s), rehabilitation exercises may be required.


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 Staffies 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.

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 Staffie, 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.

Thyroid Problems

Staffies 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.

Heart Disease

Heart failure is a leading cause of death among American Staffordshire Terriers in their golden years. Most heart disease in dogs is caused by weakening of a valve. A heart valve slowly becomes deformed so that it no longer closes tightly. Blood then leaks back around this valve and strains the heart. Pets with heart valve disease (sometimes called mitral valve disease) have a heart murmur. If your dog has a heart murmur or outward signs suggesting heart problems, we’ll perform testing to determine the severity of the disease. The same tests will need to be repeated at least every year to monitor the condition. If heart valve disease is diagnosed early, we may be able to prescribe medications that could prolong his life for many years. Veterinary dental care and fatty acid supplementation can help prevent heart disease and weight control can help diminish symptoms.

Tail Chasing

Lots of dogs enjoy a healthy game of “chase the tail.” However, for some American Staffordshire 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.


Cancer is a leading cause of death among dogs in their golden years. Your American Staffordshire Terrier is a bit more prone to certain kinds of cancer starting at a younger age. Many cancers are cured by surgically removing them, and some types are treatable with chemotherapy. Early detection is critical! We’ll do periodic blood tests and look for lumps and bumps at each exam.

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, American Staffordshire Terrier 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 Staffies. 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.

Entropion is a condition where the eyelid rolls inward, causing the eyelashes to rub against the cornea (surface of the eyeball). This is an extremely irritating and painful condition that can ultimately lead to blindness. It can happen in any dog breed; however, your Staffie is especially at risk for this heritable disorder. Surgical correction is usually successful if performed early.

Distichiasis is a condition caused by extra hairs that grow inside of the eyelid and rub on the surface of the eye. This is one of the most commonly inherited diseases in dogs, and your Staffie is more likely than other dogs to develop this painful condition. If untreated, these abnormal hairs can cause corneal ulcers and chronic eye pain. Several treatment options are available, and the prognosis is good once the hairs have been permanently removed.

Balance Problems

The cerebellum is the part of the brain that gives balance and coordination. Cerebellar Abiotrophy is a genetic neurologic disease that affects certain breeds of dogs, including AmStaffs. The problem starts in early puppyhood, with affected dogs usually beginning to show symptoms between 6 and 16 weeks of age. This condition causes affected dogs to lose the sense of space and distance, and become uncoordinated. It is not a painful condition, but the exact cause is not known, and there is no effective treatment. Dogs with this heritable condition should not be used for breeding.

Cleft Lip or Palate

Your Staffie is more likely than other breeds to be born with a cleft lip or palate, which is an opening in the lip or the roof of the mouth. Mild cases may not require any treatment, but more serious defects require surgical repair to prevent complications. We’ll check for this abnormality during his first puppy exam.

Retained Testicle

Some male Staffies have a condition present at birth in which one or both testicles do not descend into the scrotum (a condition called cryptorchidism). Instead, the testicle stays in the abdomen, which can cause problems later in life, including high cancer risk. We’ll check for this problem when your pet is a puppy; we recommend removal of both testicles if he has this condition.

Bladder or Kidney Stones

There are a few different types of stones that can form in the kidney or in the bladder, and American Staffordshire 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!

If your Staffie has an inherited condition called Hyperuricosuria (HU), he will have more uric acid in his urine. Uric acid acts like fertilizer for bladder stones and sometimes kidney stone development. A DNA test is available to test for the specific mutation associated with the disease; however, once stones are present they often must be removed surgically. By testing early, we can identify whether this is a health risk for him, and start appropriate dietary therapy to prevent problems. Without a DNA test, we may recommend frequent urine analysis, x-rays or ultrasound to make sure he doesn’t have these painful stones.

Neurological Disease

A genetically linked neurological condition that could occur in your American Staffordshire Terrier causes a wobbly, drunken gait. This condition, known as wobbler disease or wobbler syndrome, happens because there is a narrowing of the vertebrae in the neck, which pinches the spinal cord and associated nerves. If the nerves do not send signals to the brain the way they are supposed to, your dog cannot feel his feet. The first signs you will often notice are unstable hind legs, stumbling, and sometimes falling. Medications, neck braces, rehabilitation exercise programs, and surgery are treatment options.

AmericanStaffordshireTerrier2of2Taking Care of Your American Staffordshire 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 Staffies. 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 AmStaff 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.
  • She has low grooming needs. Brush her coat as needed, at least weekly.
  • American Staffordshire 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.
  • She is easy to train but early obedience and socialization are required to keep her from becoming overprotective and aggressive.
  • 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 American Staffordshire 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


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
  • General reluctance to run or play
  • Dull coat, hair loss, sluggish, weight gain
  • Coughing, especially at night or upon rising after sleeping, rapid breathing at rest
  • Repetitive, compulsive whirling
  • Excessive incoordination, beyond normal puppy clumsines
