Went to the vet today. She still has ALL of her baby teeth!!! he said he would not spay her for another three or four months now. This made me feel better but now I have another concern. My mom has a Cobbie Chihuahua. He is fourteen years old and has never been neutered. She never bred him so he has never had a "date". He is a house dog and very spoiled. I am so concerned about bringing my little one around him. When do little yorkies come into season? Should I keep her away from my mom's dog just in case? Mom says her dog won't try to get with her because she is too small. I say " a man is a man" and I don't want to hurt her feelings but I don't want her dog to touch mine....just in case!!! Anybody have any ideas about this?
