Dolly is the smallest adult dog I have ever seen, at a tiny 4 pounds she does not know she is tiny. The vet believe she is 5 years old and she had a mouth full of bad teeth so she had 18 teeth pulled. She does have a heart murmur which is grade 1 of of 6 so it is minor. She is such a fun little dog. She likes to play with other dogs, she is good with cats and just a little cuddle bug. She really is the cutest dog I have ever fostered. She is potty trained but you will need to take her out because she is too tiny to go outside by herself. If you are interested in meeting or adopting her please email fochp@yahoo.com
