Health

A UK Kennel Club survey puts the median lifespan of Miniature Schnauzers at a little over 12 years. About 20% lived to 15 years. While generally a healthy breed, Miniature Schnauzers may suffer health problems associated with high fat levels. Such problems include hyperlipidemia, which may increase the possibility of pancreatitis, though either may form independently. Other issues which may affect this breed are diabetes, bladder stones and eye problems. Feeding the dog low- or non-fatty and unsweetened foods may help avoid these problems. Miniature Schnauzers are also prone to comedone syndrome, a condition that produces pus-filled bumps, usually on their backs, which can be treated with a variety of methods. Miniature Schnauzers should have their ears dried after swimming due to a risk of infection, especially those with natural ears; ear examinations should be part of the regular annual check up. Miniature Schnauzers are also prone to von Willebrand disease (vWD). vWD in dogs is an inherited bleeding disorder that occurs due to qualitative or quantitative deficiency of von Willebrand factor (vWF), a multimeric protein that is required for platelet adhesion.

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.
