Health

Griffons have relatively few inherited health problems, but should still be tested for congenital defects, the most serious of which are Syringomyelia (SM) and Chiari-like malformation (CM). The typical life span of a Griffon is somewhere in the range of 10 to 15 years.

Birthing
Griffons usually have no trouble whelping on their own, but sometimes complications can necessitate a Caesarean section. The size of a litter is anything from 1-10 puppies. The size of the litter often determines the extent of these complications. When they are born, the puppies only weigh a few ounces (about 100 grams) and are small enough to fit in the palm of an adult's hand.

Cleft palate
One issue that is typically fatal for the puppies is having a cleft palate. It results in the puppy not receiving nourishment from the mother and eventually starvation. It is uncommon but, depending on the size of the cleft, it is possible for the puppy to survive. When it becomes older surgery can be done to close the hole.

Eyes

Most have large eyes that may require rechecks from a veterinarian.

Lacerations are a common issue amongst the breed. Because the Griffons have such large eyes and a short snout, there is very little there to protect their vision from foreign bodies. If a laceration is left untreated it can result in blindness.

As with most breeds, cataracts are a common problem as the dog ages. For many breeders it is a disappointment that the cataracts typically develop long after the dog has already been bred.

Lens luxations can be fairly common in the breed and result in secondary glaucoma

Glaucoma can also be a common issue amongst Griffons owing to the breed's facial features and eye size.

Although Griffons have a shortened snout, heat stroke is not a major concern for them as it is with other flat-faced breeds. The breed's shortened muzzle may cause respiratory problems in extreme heat, but overall they tolerate both hot and cold weather well. As with any breed, owners must use common sense and not leave them outdoors without protection from the elements or subject them to rigorous exercise during extreme temperatures, so let them in your house for cool air and some water.

Syringomyelia (SM) is a condition affecting the brain and spine, causing symptoms ranging from mild discomfort to severe pain and partial paralysis. Syringomyelia is characterised by fluid filled cavities within the spinal cord. SM occurs secondary to obstruction of cerebrospinal fluid (CSF) especially if that obstruction is at the foramen magnum. Not all dogs with SM have clinical signs. The presence of signs is correlated to the width of the syrinx and extent of spinal cord dorsal horn damage. Syrinxes can progressively expand and a dog which is asymptomatic in early life may eventually experience pain.

Health

Heart Disease
Shih tzu's are prone to multiple types of heart disease. The condition may have a poor prognosis depending on when it is diagnosed and the stage of the disease when it is discovered.

Brachycephaly
Due to the ideal of beauty regarding the shape of the face the skull malformation brachycephaly was increased by breeding selection. This short nose causes problems like skin sensitivities such as dermatitis, bumps, and rashes.

Eye issues
It is very common for Shih Tzu's to develop eye problems at any age, and even more so once they are older. Most veterinarians will recommend eye drops to assist with any eye irritations. Some dogs have allergies which causes excess discharge around the eye. Older Shih Tzu are known to develop cataracts which can be corrected with surgery. If not treated, the dog may become blind in the eye that has the cataract. The distinctive large eyes can easily be scratched which may cause an ulcer. The dog will normally have the injured eye closed or half closed and may have excessive tears. The most common problem of Shih Tzus concerning eye conditions is the formation of epiphora caused by the fur on the eyelids scratching the conjunctiva and the cornea. However this can be mediated by the application of prescribed eye drops from a veterinarian.

Hair issues
Untrimmed hair can be an issue. This is remedied with a top knot or a short puppy cut. Shih Tzus have hair which can grow lengthy. Long hair is required as a show coat and is required generally to be brushed or groomed once a day. Hair longer than a puppy cut often causes issues, including hair covering the eyes of the dog, preventing good visual acuity.

Ear issues
A very common issue for Shih Tzu's is the development of ear infections, as they have a long coat and hair grows in their ears. If ears are not plucked and cleaned often, ear infections will reoccur and need to be treated with ear cleaner and possibly medication, prescribed by the veterinarian. Ear infections may be spotted by an odor coming from the ears, as well as frequent shaking of the head and scratching of the ears.

Skin sensitivities
The Shih Tzu's skin is particularly sensitive and prone to allergies. Ideally, they should be bathed every two to six months to maintain hygiene and prevent skin irritations. They are also prone to stomach issues, and most have delicate appetites.
