Wow - this is great information. Yes, I am absolutely positive that the breeder would have said something had she noticed. She told me about his ticking early on (he has some C-Quest in his line, which I am told is heavy with ticking). At first I was wishing he didn't have it, but he is gorgeous and I do think it adds character (even though I know it doesn't do him any favors in the ring). My daughter also loves to kiss every "freckle," so that makes it extra cute. His sister's white is completely clear.
Glad to know that the little bald tail tip doesn't affect their chances in the ring. Don't know if we are headed that way, but I have a show contract on him. I really want to concentrate on obedience and therapy dog work with these two. I am thrilled with their temperaments - you can't look at them without them wanting a snuggle. Also, we are clicker training and after 3 days, have them sitting, shaking and laying down (admittedly, sometimes more reliably than others).
Okay, that got off-topic! Anyway, all this is to say thank you for your information and reassurance.
