Hi everyone! I am in search of a little guidance... I fell in love with a friend's 3-lb Yorkie two years ago, and have wanted one ever since. I am in touch with that dog's breeder but they may not have puppies available for another year or two. I want to train my future pup to be a therapy dog so I can volunteer with her at local hospitals, hospices and retirement homes.. I'm wondering if 3-lbs. is too small/fragile for that kind of work? I also travel/fly frequently so I like the idea of a smaller dog because it's obviously easier to carry. Does anyone have experience with a breeder of small but healthy pups in So. California that they trust? I have read so many nightmare reviews and stories about breeders & pet stores nationwide... I want to make sure I enter into this as educated and prepared as possible! Thanks in advance!
