Tibetan Mastiff health: what owners should know

The Tibetan Mastiff is generally considered hardy for a giant breed. Conditions reported in the breed include hip and elbow dysplasia, hypothyroidism, entropion (inward-rolling eyelids), panosteitis in growing dogs and, rarely, an inherited neurological disease called canine inherited demyelinative neuropathy. Responsible breeders score hips and elbows, test thyroid function and check eyes.

Older TMs benefit from a thick orthopedic bed and non-slip rugs on smooth floors, which make getting up easier for a heavy dog. Call your vet about a limp that lasts more than a day or two, squinting or constant tears, weight gain combined with a dull coat and sluggishness, or a swollen belly with unproductive retching, which is an emergency.
