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

Alert, curious, and busy
Adaptable to a wide variety of living conditions
Even temper and gentle disposition
Good watchdog with a loud bark
Lively, with a friendly personality
Bold, steady, and fearless
However, no dog is perfect! You may have also noticed these characteristics:

Early obedience training and socialization is recommended
Needs frequent attention from her family
Likes to dig
Sees cats and small animals as prey unless trained otherwise
Can be possessive of toys and food, tending to show dominance
Needs daily exercise
Is it all worth it? Of course! She’s full of personality, and you love her for it! Sealyham Terriers form close bonds with their owners and enjoy being part of a family. With a patient and consistent leader she makes a cheerful and devoted companion.

The Sealyham Terrier originated in Wales during the mid-1800’s and was bred for the typical terrier tasks of vermin control and hunting badgers, otters, and foxes. The Sealyham Terrier is calm and relaxed indoors, but is always ready for action and happy to investigate. They are loving and charming pets but can be a bit snippy with small children or small animals. Sealyhams require only moderate exercise: a leisurely daily walk will keep them happy. The Sealyham Terrier is a generally healthy breed with an average lifespan of 14-16 years.

Your Sealyham 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 Sealyham. By knowing about health concerns specific to Sealyham 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 inSealyham Terriersto 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 Sealyham 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 Sealy 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 Sealyham Terrier
Dental Disease

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

Sealyham 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, herage, and other factors.

Obesity

Obesity can be a significant health problem in Sealyham Terriers. It is a serious disease that may causeor 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 Sealy’s body, inside and out. Everything from fleas and ticks to ear mites can infest herskin and ears. Hookworms, roundworms, heartworms, and whipworms can get into hersystem 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 Sealyham 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 Sealyham 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, Sealyham 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.

Glaucoma, an eye condition that affects Sealyham 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!
Cataracts are a common cause of blindness in older Sealyhams. 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 Sealys, 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.

Dry eye, also known as keratoconjunctivitis sicca or KCS, is common in Sealyham Terriers. The tear glands no longer produce enough tears to keep the eye moist, which results in sore, itchy eyes and infections. Ouch! Symptoms include a thick discharge, squinting, pawing at the eye, or a dull, dry appearance of the eye. This is a painful condition; please call us immediately if you notice any of these signs. We’ll conduct a tear test when we examine him. If he has this disease, we’ll prescribe ointment that you’ll need to apply for the rest of your dog’s life.

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 Sealyham 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.

Progressive Retinal Atrophy (PRA) is an inherited disease in which the eyes are genetically programmed to go blind. Unfortunately, Sealyham 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.

Sometimes small strands of tissue that were meant to disappear soon after birth remain attached to the iris. When this happens, it’s called Persistent Pupillary Membrane, and your Sealyham Terrier is more likely to have this condition than other dogs. Fortunately, these tissue bits usually don’t hurt or impede vision, but occasionally they can cause problems.
Back Problems

Intervertebral disc disease (IVDD) is a common condition in Sealyhams. The disease is caused when the jelly-like cushion between one or more vertebrae slips or ruptures, causing the disc to press on the spinal cord. If your dog is suddenly unable or unwilling to jump up, go up stairs, is reluctant to move around, has a hunched back, cries out, or refuses to eat or go potty, he is likely in severe pain. He may even drag his back feet or be suddenly paralyzed and unable to get up or use his back legs. If you see symptoms, don’t wait. Call us or an emergency clinic immediately! For less severe cases, rest and medication may resolve the problem. In many cases involving paralysis, we’ll recommend surgical removal of the ruptured discs (within 24 hours of the onset of symptoms to get the best results). As with so many other diseases, weight control helps to prevent this problem. You should also use ramps or steps from puppyhood on so that your dog doesn’t spend a lifetime stressing his back by jumping on and off of the furniture.

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 Sealyhams 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.

Allergies, swimming, overgrowth of hair in the ear canals, or an accumulation of earwax can all predispose your dog to ear infections, which are painful and annoying. Sealyhams are very often afflicted by allergies, which cause itching and inflammation in the ears and elsewhere. The earlier we diagnose this disease, the less discomfort and pain he will suffer. Be sure to call us if you notice him scratching or shaking his head, a foul odor from the ears, or if his ears seem painful to the touch. By monitoring for ear infections and treating them early, we also reduce the likelihood of eardrum damage that can lead to deafness. Most ear infections tend to recur until we work together to control the underlying cause.
Mange

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 Sealyham, 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.

Degenerative Myelopathy

Degenerative Myelopathy is a neurologic condition, similar to ALS or Lou Gehrig’s Disease in people, that causes weakness and poor nerve function in the hind legs. It affects Sealyhams more frequently than other breeds. If your dog has this disease, he will become increasingly weak and disabled in the hind legs and will eventually suffer from paralysis in his hindquarters, along with incontinence. Rehabilitation, exercise, acupuncture, and dietary supplements can be helpful, but there is no cure. A genetic test is available to determine whether your dog is at risk for this heritable disease.

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 Sealyham 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.

Reproductive Difficulties

Breeds with a large head and small pelvis are more prone to difficulties during the birthing process. Her pelvis is just too small to pass puppies and a C-section is often required for her health and that of her puppies. If you are interested in breeding your Sealy, speak with us first. We can help you make an informed decision based on body conformation of both sire and dam.

Dental Abnormalities

Teeth abnormalities are often genetically induced and are relatively common in dogs, especially in purebred dogs like your Sealyham. 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.

Deafness

Heritable deafness has been noted in some Sealy 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.
Taking Care of Your Sealyham 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 Sealyhams. 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 Sealy 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. Twice a year stripping or clipping is also required for her wiry double coat.
Sealyham 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 is well suited to apartment life as long as she is given a daily walk and frequent play sessions.
She is an athletic dog that excels at dog sports like agility, obedience, and Earthdog.
She has a strong chase instinct, so she needs to be leash walked and a fenced yard is a must.
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 Sealyham 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
