My american pitbull terrier has come into her first heat she is 12 months old and app.55lbs if she breeds can it stunt her growth?
No, it will not stunt her growth but she may have problems giving birth so you should be prepared financially in case she needs a c-section. Her bones in the hips are not fully developed and the pups can get stuck. We usually recommend breeding at 2 years of age. I always recommend spaying, there are enough dogs out there that needs homes . vetcare
