If Ace is an only puppy, count the # of kibbles you put in his bowl in the morning and then recount them in the afternoon. Even though you can't be positive that he ate the missing kibble, it would give you a place to start.
If he is active, and is peeing and pooping then he must be eating. Some dogs are don't like to be watched when they are eating .... I call them "closet eaters". |
