Fellow Lab parent here How old is Oscar? My Star, who is now 5, had the biggest belly as a puppy! She looked like she swallowed a balloon! But both the breeder and vet said that was normal for a growing puppy. She didn't eat more than the recommended amt. and was a VERY active little pup! She's a svelte 62 lbs. now and no "belly" in sight I think she was around 4 months before she lost her baby fat! If you're feeding Oscar the right amt. of the proper food and he's getting good exercise, I'd try not to worry, Dad Of course, every once in a while they do get a little gas If you're really concerned, you might want to check with your vet, just to ease your mind Oscar sure is a cutey! Now, here's my baby Star and her BIG belly!
