When do American Staffordshire terriers reach full maturity? I got him neutered at 6 months, not sure if that matters

Hello. Full physical maturity ( growth ) is completed by 18 months of age. Otis may continue to put on weight & girth until 2 years of age. Neutering does delay final growth a little bit as the growth plates close, so a neutered dog will take up to 6 months longer to finish growing as an intact one. Hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.
