My new Baby (I'm not sure of a name yet so we call her baby) puppy teeth aren't all grown in yet. She will be 10 weeks tomorrow and she weights 1lb. The vet also said she has LP in one of her back legs but that is wasn't that bad. I've been reading everything on here about it and he didn't give it a number in the one to 4 range but said it was mild and so far he didn't think she would have to have surgery but he would keep an eye on it and watch it carefully. She is a tiny little thing but full of energy and is eating well. I also give her nutri cal 3 times a day. She was the runt of the litter her parents are mom 4 lbs dad 6lbs. Her litter mates were much bigger then her and about the size of my other 2 puppies Chloe and Claire when I first bought them home. I've kind of went Yorkie crazy I now have 4 dogs, Casey my Maltese, and Chloe and Claire are both 4 months old. I'm alone most of the time because my children are older and live out of state and my husband works long hours. so I have the time to devote myself to these baby. They are bringing such joy to my life.
