Athena is associated with Athens, a plural name, because it was the place where she presided over her sisterhood, the Athenai, in earliest times. Mycenae was the city where the Goddess was called Mykene, and Mycenae is named in the plural for the sisterhood of females who tended her there.
Hypoallergenic coat requires grooming: Because the Wheaten Terrier has a single coat, it is often a better breed for people with allergies. It is considered a hypoallergenic dog, however, because it has hair that grows constantly instead of fur that sheds. As a result, the wheaten coat needs frequent grooming.
End of. Allergies are to the dander or saliva - all dogs have dander and saliva. Hypoallergenic merely means the breed is known to produce LESS dander, doesn't drool, and doesn't shed (the coat itself has nothing to do with allergies btw, shedding coats just tend to produce more dander.) The Chihuahua is NOT on any known hypoallergenic list. Again, they need to talk to a specialist to see how severe their allergies are and what they can do to minimize symptoms or exposure. The only way to know if they will be okay with a dog of ANY breed would be to have them spend serious time with the individual dog (if possible) or the breed.
