My dog is a mini-fox cross chiwawa (sp?). So I've been told, especially vets, they're the type of person to ask if you need to know something about a dog. Never ask someone purely on the basis that they themselves own a dog therefore must know what kind of dog it is unless your trying to maintain an awkward conversation.
you know:
me: So, hows your mother doing?
her: she died, flung herself into the tract of an oncoming fleet of Bentleys. *starts crying* they..were her passion.
me: Your dog, what type of breed is it?
If people ask me what type of dog I own, I tell them its a hyena.
No shit drawings today, because? No reason.
