It is to your benefit to know about one or two common diseases that your dog could get.

Bloat:

You’ll notice your pet’s stomach being swollen. Bloat is a disease which can become dangerous because the stomach can twist.

You need to get him to the vet as soon as possible.

Kidney Disease:

This is also a disease that any dog can develop and can be a complication of another pet disease such as Lyme disease. One of the first signs of kidney disease in dogs is drinking more often than usual and also urinating more often.

He’ll lose his appetite and be lethargic and likely lose weight. Kidney disease is a serious disease and you will need to get your pet to the vet as soon as possible.

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.

The Chilean Fox Terrier is a low maintenance breed and this means you won’t be having to part with any money on grooming sessions for him. He’ll basically require a brushing twice a week.

Diet:

These large, strong dogs do well on good quality food. If you opt to buy him commercially manufactured food, make sure it is the top quality one free of unwholesome ingredients such as preservatives, colorants and useless fillers.

Invest in the best quality ones that have nutritious minerals and vitamins. Try and give your dog some home-prepared food too – boiled chicken, brown rice or pasta, spinach, sweet-potatoes and carrots.

Never feed your dog things such as chocolates, peanuts, crisps, grapes, onion and food with spicy flavorings. This will just ensure digestive problems and having to get your dog to the vet.

Cool, fresh water should be available at all times.

Grooming:

The Tosa’s short coat isn’t going to require too much attention. A good brush twice a week will keep it free from loose hair and keep its shine and gleam. It’s why the dog is looked upon as being low maintenance.

Beyond that, he will need to have his nails trimmed. When brushing him, check him over for parasites – ticks and fleas, check for unusual lumps and look inside his ears for signs of redness.

Exercise:

These dogs are calm and fairly low-energy. Nonetheless, to maintain good health, he will need to be exercised. Ball games outside are always a good idea as well as nice long walks. Hikes into the countryside will be wonderful for this big dog.
