I'm worried about my puppy pomeranian being overweight. Theo is six months old and I just got him two days ago from a breeder. I took him to the Vet for a regular checkup and he said that he was 9 pounds and should weigh 6. I'm worried about his health, because he also makes a type of wheezing sound when he plays and runs. How can I help him lose weight or is this normal with pom puppies?
P.S. His father is 5 pounds and his mother 7. Thanks!
