Cute little pup. Every Yorkie has different hair. Ours is thin. You can try the things mentioned or just let the hair grow as it should under normal conditions.
As for food, that really depends on the puppy. We were all gung ho to get Bailey a bag of Blue Buffalo. He refused to touch the stuff. Even taking up his dish and later putting it down, he wouldn't eat it. We went to another place who gave us samples. When he dug in to one, we knew we had struck gold. |
