My Fiona is very small. She is 9 months old and weighs 2lbs 8oz.The vet said it is unlikely she will grow much more. She has been healthy but when we first got her she fell off our back porch and broke 3 bones in her paw. Don't want to scare you but the little ones need a little more attention. Our porch isn't that high and I never would have thought she would have broken anything if she fell. We never put her on the bed or couch. We just have to be a little be more cautious. She has a wonderful personality and was growing a long coat until the winter brought on dry skin. We are taking care of that but I think if that hadn't happened her coat would already be close to the ground. I am learning, good food and possible suppliments help with the skin and coat. Might want to look into it if you are worried about growing it out. I think I would like it long too, just to see!
Good luck!
