Tommy had shorter hair on his legs but now they are getting alot fuller. His hair was allittle thin too. But it is lookin great now he is 3.5 lbs at 6 1/2 months so it might be just in the smaller dog.
I also had a big boy fluffy and lots and lots of hair he was 7 1/2 lbs at 10 months. So thats why I think it is in the smaller dog but I could be way off on that.. You can look at Tommy's pic's and see as he was when I brought him home till now.. Its under monyka415.
GOOD LUCK!!
