My yorkie is almost 2 and some days he just doesn't have an appetite. And when he was a puppy, there were days he would eat and there were days he wouldn't. I was concerned and called my breeder. SHE SAID to put him on a feeding schedule and if he doesn't eat what's in front of him aka if he walks away from his bowl, then take it away. He'll be hungry for his next meal, she said.
 
And she was right! I was concerned about the days he wouldn't eat, but putting him on a schedule was the best thing we ever did for him
