Akita Inu vs Gran Mastin de Borinquen - Breed Comparison

The Akita Inu, originating from Japan's snowy Akita Prefecture, has a long-standing legacy as a powerful hunting dog and loyal companion. Bred in the 1600s to track large game like boar and bear, the Akita quickly earned its place among Japanese nobility as a guardian and symbol of courage.

Its dignified nature and unwavering loyalty were immortalized in the true story of Hachikō, an Akita who waited nearly a decade for his deceased owner at a Tokyo train station. This devotion captured national and global admiration, leading to the breed’s recognition as a national treasure in Japan.

After World War II, American soldiers introduced Akitas to the West, giving rise to a larger, more robust variation known as the American Akita. Today, the Akita Inu remains a cherished breed worldwide for its strength, loyalty, and quiet dignity.

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.

Akitas thrive on routine exercise, such as long walks or playtime in a secure area, but they aren’t overly energetic. Training and socialization should start early, using positive reinforcement and calm, firm leadership to manage their independent and protective nature.

They are best suited to homes where they are the only pet or properly introduced to others. Akitas are clean, quiet, and typically bond closely with their family, so providing mental stimulation, affection, and clear boundaries is key.

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

Grooming:

The Gran Mastin de Borinquen, with his short coat, is a relatively low maintenance breed. Brush him at least twice a week to keep the coat free of loose hairs. Other grooming requirements are keeping his ears clean and dry. You can ask about alcohol wipes at your local pet shop to use in his ears. Check the nails too and remember to brush his teeth a couple of times a week to avoid dental decay.

Exercise:

You won't find the Gran Mastin de Borinquen being a particularly high energy dog but he also isn't a couch potato. If you enjoy a walk every day for your own good health, include him in these walks and give him a game of ball every now and again.

Diet:

This Mastiff -type dog is large, and they tend to be fairly lazy, not using up great deals of energy. Young dogs however use up more energy and will require a diet with good quality protein.

Dogs that have been spayed or neutered as well as senior dogs will require less calories. If you buy commercially manufactured food, check the labels carefully and buy high quality food for a large breed.

Don't just feed your Gran Mastin kibble everyday but alternate it sometimes, mixing in some raw meat into his kibble or mixing in some cooked chicken, rice and vegetables.
