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.
Known as the Olympus Dog or even simply as the Greek Shepherd, the Greek Sheepdog is a large to giant molosser dog from Greece. His purpose has always been to guard flocks and livestock from predators and he has been around for hundreds of years, looking much like the Great Pyrenees.
It is believed that the dog was likely bred with a number of breeds – both local and non-local dogs.
Unfortunately there were no records kept of the development of the breed but today the Greek Sheepdog remains a rare and fairly unknown breed outside of Greece.
It's numbers are dwindling in Greece too and since 1998 the Greek ARCTUROS has made attempts to save the breed, starting the Greek Shepherd Dog Breeding Program.

This is a disease of the heart muscle. The heart is enlarged and unable to have the right heart rhythm. The distended muscle isn't able to push the blood through the heart chambers to where it is needed. Cause for this dilated heart can be genetic, nutritional, infectious or metabolic.
Because taurine and carnitine are involved in good heart function, and low levels of these amino acids can cause symptoms of dilated cardiomyopathy, supplementation is useful, especially if you feel your dog isn't getting in the right kind of food.
Borreliosis, a bacterial infection, causes Lyme disease, transmitted by the Ixodes tick. The tick bites the dog and the toxins gets into the dog's bloodstream, with the bacteria travelling to different parts of the body.
