hi
i have a 1 year old female westie and there is a possablity that she my be pregnant. my mom has asked my to ask if any one knows around what time do pregnant dogs loose thier hair on thier bellys.
what kind of dog is it? They dont loose hair before the puppies but some breeds will thin out after the puppies . They will show around 6th week They do the most growning the last 3 weeks of 9 63 days .You should call a vet monday and get her in.DO you have her on a good puppy food?
