[QUOTE=Bitsy] I love these dogs but hate calling them "mutts", is there a nice way to say this? I usually just say mixed breed.

A Purebred Heinz 57.

That's another popular term for "mutts".
I have had MANY Heinz 57s over the years and honestly there is no difference (except I find them a lot smarter lol) b/w a "mutt" and a purebred. Both are great dogs. If you truly do want this Yorkie puppy, tell your husband. Also explain to him that just b/c Lexi has had a few issues doesn't mean all Yorkies do. ANY dog can have problems. I had one lab with Congestive Heart Failure. Did my other 2 labs have it? Nope, they were perfect actually. lol Every dog is different. Good luck!
