He certainly looks healthy and is a little doll.  JoJo did the same way.  He will always be a little thin because he is long but he is very solid.  Also, like several others, he really had a growth spurt about 7 months and now at 11 months weighs 4 lbs.  As long as your puppy has plenty of energy, bright eyes and a shiny coat, sounds like he is just fine.     |
