I got my teacup dog Daisy from a lady in Langsing, Michigan like 3 weeks ago. She breeds Teacup/Toy Sized Poodles and Shitzu's. Both of her parents were on site when I bought her and they both seemed very healthy. The dad Poodle weighed around 3 pounds and the mom Shitzu weighed about 4 pounds. She did give me a guarantee when I bought her and I took her to 2 vets already and they said she was completely healthy, she also had one of those fecal smears done. I never told them about how she shakes after she eats because I just noticed her doing this yesterday. She is do for a shot Sept. 2 this Friday so I am going to mention it then. Other then the shaking after she eats she acts completely normal. Amy.
