My 6 month old Cavalier puppy has started acting like he's not interested in eating. I thought maybe he wasn't getting enough exercise so I started walking him longer and more often...no change. His activity level is the same as far as his personality and his playing habits and no changes in potty or anything, just doesn't seem interested. I feed him Wellness Puppy. I'm thinking of switching to Wellness Adult and see if he likes that better. Any ideas?
