My little yorkie girl is 10 months old and is in heat as of this past Saturday. A friend of mine has a little yorkie boy who is around the same age...should I breed my baby girl now? I really don't want to have to go through this heat process again...but I'm worried about her. Won't she change after she has puppies? What happens after the puppies are born? Will she get depressed? Ugh...decisions!
