Why i was confused is because our vet said it could be normal for him to lose weight because he is so active and runs around alot and is also growing, and my friend said her vet told her goldens grow length wise instead of wide or something in that matter. so i wasnt sure if he was just growing and very active or losing weight for some other reason, he is very athletic looking and muscular but i just think he looks skinny and i like my dogs having meat on them more than he seems to i dont like them overweight just chunky i guess.
