The Akita Inu is generally a strong and resilient breed, but it is prone to several genetic and breed-specific health issues.

Common concerns include hip and elbow dysplasia, progressive retinal atrophy (PRA), and hypothyroidism, all of which can affect mobility, vision, and metabolism.

The breed is also susceptible to autoimmune disorders like VKH-like syndrome and sebaceous adenitis, a skin condition causing hair loss and irritation. Additionally, Akitas may experience bloat (gastric torsion), a life-threatening emergency common in deep-chested dogs.

Regular veterinary care, proper diet, and responsible breeding practices are essential to help minimize health risks and ensure a long, healthy life.

If you see your dog with a bloated stomach and acting in a strange, lethargic way, get him to the vet immediately as bloat can be life threatening.

Regular vet checkups, a balanced diet, and proper social interaction help keep your Akita healthy, happy, and well-adjusted.

Grooming:

As an average shedder, the smooth, shorthaired coat is easy to groom, and a good brush twice a week will be adequate.

The Giant Maso Mastiff has floppy ears and therefore these should be checked for ear infections. Wax build up and dirt will need to be checked and cleaned.

His nails will need to be clipped, especially if they don’t wear down on their own and his teeth will need to be cleaned 2 or 3x a week to avoid dental disease.

Diet:

With a large dog breed puppy such as the Giant Maso Mastiff, rapid growth is a risk factor for developing joint and bone conditions. The growth period can last till 12 months and puppies of large breeds should actually have their caloric intake adjusted during this growth period.

It is important to ensure that your puppy grows at a slow, steady rate. If you are feeding dog food from the commercially manufactured range, if you aren’t sure, speak to your vet about large breed dog foods. You want to be sure that this gentle giant of yours receives the best dog food there is, whether commercial branded dog food or your own home-made food. Good nutrition is imperative for the health of your pet.
