Hi, I have a shih tzu and was wondering about this also as he seems to walk funny from the rear view. So after reading your post, I googled hip dysplasia shih tzu and went to a site that said yes its hereditary and can be treated by vet. Also, retinal atrophy is genetically linked and can lead to blindness. These little dogs have a tendency to suffer eye injuries so we must be careful with them.Also, thyroid disease can be found in some.
Hope that helps. memaw-Jan
In general, hips are a problem in larger dogs, such as Shepherds and Great Danes. Small dogs seem to have more internal problems, such as kidney diseases and bladder infections.
