Giant Maso Mastiff vs American Hairless Terrier - Breed Comparison

Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.

The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.

From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.

The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.

The Giant Maso Mastiff is a fairly new dog breed so you aren’t going to find much history on him.

The breed is highly susceptible to sunburn, rashes, pimples, and allergies. They often need clothing in all seasons to protect them from the heat of the sun or from the cold. The skin must be cleaned regularly often daily with soap and water. This is especially true if sunscreen is used as they are open to skin infections.

Hip dysplasia is also a common issue for this small breed.

There has always been the concern with joint disorders in large breed dogs. Both hip- and elbow dysplasia can occur with your Giant Maso Mastiff, more so if you overfeed him as a puppy and he grows too fast.

With hip dysplasia, the long bone of the leg forms incorrectly. This can lead to pain and lameness with your pet.

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.

Puppies need about 400 calories a day whether you feed four times or two times. The adult American Hairless Terrier needs about 500-600 calories per day. This might be half a cup to a cup per day.
