this dog is about 5 years old. my husband said before she goes through heat she gets a stuffed animal like her baby... she really wants to be a mother :(. I feel sad for her.. she isn't spayed and they keep the older dog away. I know breeding is bad and all but I would so keep the puppy if they ever mate. I think that's her lifelong dream to be a mother. she let's no one but me and my husband touch her "baby".
