I am sooo sorry to hear about your ordeal. We too have purchased our Yorkie from Chaffin, but we dealt with a witch named Merri. She is a real peach. Our little Madi is ok now, but we she arrived we brought all 1.5 lbs of her to the vet and she had the worst strain of kennel cough that our vet has ever seen. It took 3 anitbiotics and cough syrup with codine to help her get better. She then had to be dewormed and had a strange rash on her ears that to this day our vet doesn't know what it was. It caused all of her fur on her ears to fall off. It has grown back and she is as cute as ever. She also got some strange virus that caused her to lose 4oz. in 2 days from vomiting and diarrhea. She is now 7 1/2 months old and we just had her spayed and she did very well and healed up nicely. She is the love of our lives and can't imaging our life without her. Oh yeah, our puppy was sent up without her papers and of course Merri from Chaffin is giving me the run around on them, it is going on 3 months of me trying to get them from her. I am not really concerned about the akc stuff, it is just the point that she advertised akc registerd yorkies and then doesn't send you the paperwork. I truly believe that every dog has it's day and what comes around goes around. I love our little girl and she is staying on the petite size. She just reached 5lbs. and 7 1/2 months old. She does have the greatest little personality and disposition. I think it is from my husband and I working with her. She does have some major separation anxiety and as soon as you put her into her crate and shut the door, she will pee and poop and step in it. She is fine if you leave the door open, she will lie down and take a nap. The trainer that we go to with Madi thinks that she was in bad living conditions to pee and poop where she sleeps. I hope things get better for your situation.
