The weight of your pit is ok. Don't worry.
What's The Average Weight For A Pit Bull? My Pit Bull Terrier Is 2 Y/o And Weights 67lbs. My Husband Says She's Too Fat.
It depends on the bloodline and build of the dog, 67 lbs for some pits could be too skinny or too heavy. You should be able to just barely feel the pits ribs. Thats how you know if he's the right weight. And remember, muscle weighs more than fat.
