Cao Fila de Sao Miguel vs American Hairless Terrier - Breed Comparison

This Molosser type dog originated on Sao Miguel Island in the Azores, a region of Portugal. Known also as the Sao Miguel Cattle Dog or the Azores Cattle Dog, the existence of the Cao Fila de Sao Miguel has been documented since early in the 19th century.

The dog has always been used as a cattle dog but today it remains rare outside of Portugal. In was in 1984 in Portugal that the first written breed standard was published in Portugal. The Cao Fila de Sao Miguel then earned recognition with the Portuguese Kennel Club.

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.

Dog bloat:

This is a dangerous illness that can affect any dog – small or large. This is when the dog’s stomach fills with fluid or gas so that it expands. The stomach then puts pressure on other organs and your dog can have trouble breathing. There is also no blood flow to the heart. Sometimes the stomach of the dog twists and your pet can go into a state of shock. Recognize the symptoms of bloat – a swollen stomach, drooling and wanting to vomit but nothing coming up. Get your dog to the vet immediately.

Abscess:

An abscess can be so painful for your pet often when your dog has a thick coat it could go undetected. If an abscess on your pet doesn’t burst, or even if another abscess appears, a vet must be consulted and a course of antibiotics given.

Ear Infections:

Ear mites, dirt and a build up of wax may cause your dog to scratch at the ear, shake his head or hold it on one side. There may even be a foul-smelling discharge. Your dog will need to have his ears cleaned. Special ear drops can rectify the problem. Remember that hot, red ears will require veterinary attention.
