Sometimes I see them capitalized, but more times not. I guess it would be the same as dog, or horse, breeds. Does anyone know? I tried to look it up, and it looks like some would, but others might not, depending if a country, or city/state, is in it's name. Kinda like French fries Rhode Island red (capitalized because name of a state) silkie (not capitalized because it is not a city, state, or country) So... What do you think???
