I admit to being totally ignorant when it came to breeds and mixes. I started out wanting to adopt or rescue from the SPCA but they had nothing but huge dogs so we ended up at a pet store (just to look) where we fell in love with something called a yorkiepoo. I will never regret it because not only do we love Porkie but we know if we hadn't gotten him when we did he would be dead now! The pet store would never have put out the $1,300.00 it cost us to save his life after he was starved by them (anorexia) (2 lbs and only fed twice a day) as well as hypoglycemia and dehydration. Considering everything I hate the mere idea of puppy mills/breeders or anyone else doing this just to make a buck especially when everyone suffers if there are health problems early on or even later (possible liver shunt) but on the other hand I just can't regret having our Porkie for even one minute. It's a real dilemma
