Hip Dysplasia:

This is where the thighbone doesn't fit properly into the hip joint. Hip dysplasia spells pain for your dog and he may show lameness with one or both rear legs. Arthritis can develop too.

Hip dysplasia is hereditary, but it can be worsened by allowing your dog to become obese and from injuries from leaping off your bed for instance.

Progressive Retinal Atrophy (PRA):

Reputable breeders have the eyes of their dog certified each year by a veterinary ophthalmologist and they don’t allow the dogs to produce puppies.

The Tosa is a formidable looking molossoid, but even so, this big, calm dog can succumb to illness. Some of these diseases you need to be looking out for include bloat,hip dyslasia and eye conditions.

Bloat for this dog can be life-threatening, and can often be because the dog is too hungry and he gobbles up his food quickly. Bloat is when gas can't escape, the stomach swells and twists – very dangerous. Rather give your dog two smaller meals – one in the morning and one in the evening, or even give several smaller portions throughout the day.
