Caring for Your Faithful Companion

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

• Sweet, gentle, and sensitive
• Loving and loyal to her owners
• Adaptable to a wide variety of living conditions
• Quiet—not much of a barker
• Quirky, entertaining personality
• Easily motivated and trainable

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

• Exhibits signs of separation anxiety if left alone too much
• Does not tolerate harsh reprimands or negative-reinforcement training
• An indoor dog that doesn’t do well in the heat
• Makes a lot of snorting, snuffling, and wheezing noises, and she may snore
• Needs frequent attention from her family
• Standoffish toward strangers

Is it all worth it? Of course! She’s full of personality, and you love her for it! She is lively and charming; her highest aspiration is to become your trusted companion.

While most people believe this fantastic breed came from Japan, it actually originated in ancient China and is also called the Japanese Spaniel. She was bred to be a royal lapdog. The Japanese Chin is playful and easygoing but is not recommended for homes with small children. They are intelligent and can quickly learn to perform tricks. The Japanese Chin thrives as the center of attention. They are described as having a cat-like attitude: alert, independent, clean, and often found sleeping in high places. Chins are easygoing and happy companions with minimal exercise needs.

Your Japanese Chin’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 Chin. By knowing about health concerns specific to Japanese Chins, 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 Japanese Chins 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 Japanese Chins. 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 Chin 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 Japanese Chin

Dental Disease

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

Japanese Chins 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 Japanese Chins. 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 Chin’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 Chin 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 Japanese Chins

Heart Disease

Heart failure is a leading cause of death among Japanese Chins 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.

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, Japanese Chins 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 Chins. 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. Notice how the lower lid curls in towards the surface of the eye to cause irritation.

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 Chin 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 Chin 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.

Normal Knee

Knee Problems

Sometimes your Chin’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.

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 Chin’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 Japanese Chins 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.

Spinal Cord Injuries

Japanese Chins are more likely than other breeds to have instability in the first two neck vertebrae (called the atlantal and the axial vertebrae). This can cause a sudden spinal-cord injury in the neck. If your dog is suddenly unable or unwilling to jump up or go up stairs, cries for no apparent reason, or tries to turn or lower his head when you pick him up, he is in pain. Call us immediately! We’ll control the pain with medication, and sometimes surgery is recommended. As with so many other diseases, weight control helps to prevent it. With this breed, it’s important to use ramps or steps from the time your dog is a puppy so that he doesn’t spend a lifetime stressing his neck by jumping on and off of the furniture.

Spinal Deformities

Japanese Chins are more likely than other canines to be born with spinal deformities (a condition called hemivertebrae), which may lead to spinal cord damage, instability, or disability. We’ll take X-rays when he is young to ensure that we identify problems early because symptoms can worsen with age, weight, and sometimes activity. During his life, if he develops symptoms of any back problems, we’ll rule out any other causes, such as a slipped spinal disc or arthritis and may prescribe medication, acupuncture, or rehabilitation.

Liver Problems

Your Chin 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.

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 Japanese Chins 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.

Narrow nostril openings make breathing air in more challenging.

Respiratory Distress Syndrome

This disease, also known as brachycephalic syndrome, affects dogs with a short nose, like your Japanese Chin. He has the same amount of tissue in his nose and throat as the longer-nosed dogs, but there’s no place for it to go. As a consequence, the soft palate (the soft part at the back of the roof of the mouth), is too long and hangs down into the airway. The nostrils are often too small, and sometimes the trachea, or windpipe, is narrow and undersized. All of these things lead to a narrow and obstructed airway. Many of these dogs can barely breathe! Watch for exercise intolerance, loud breathing, coughing, bluish gums, or fainting. With his short nose, he is also more likely to develop other problems, such as flatulence from excessive air intake, pneumonia from aspirating food, or heat stroke. In severe cases, surgical correction may be recommended.

Retained Testicle

Some male Chins 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.

Thyroid Problems

Chins 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.

Taking Care of Your Japanese Chin 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 Chins. 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 Chin 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.
• Japanese Chins 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 daily walks and short play sessions.
• She is highly intelligent and can be taught to perform a variety of tricks to keep her mentally stimulated.
• 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 Japanese Chin 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
• Coughing, especially at night or upon rising after sleeping, rapid breathing at rest
• General reluctance to run or play
• Unwilling to jump, cries when moving head
• Slow or stunted growth; sometimes seizures after eating
• Any abnormal shaking, trembling, or excessive involuntary tremors
• Loud breathing, tires easily at exercise
• Dull coat, hair loss, sluggish, weight gain
• 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.
