However, just like other dogs, he can be prone to certain health conditions such as hip dysplasia. When a dog is diagnosed with hip dysplasia, the socket part of the joint is poorly developed, so that is causes abnormal friction.

Inflammation and pain can be the result and your dog can become lame. Unfortunately, rapid weight gain with puppies can put more stress on the hips, and diets without the right balance of vitamins and minerals can be bad for good bone development.

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.

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.

To help with eliminating health issues always choose a reputable Tosa breeder. You’re not likely to find one of these dogs in a dog shelter.
