This is Clara, family rescued pitbull terrier. 1 year ago. Her dog wrapper was too big for her then but she loved it. We adopted her 2 years ago in December. Accordingly the pit bull terrier grows to a height of 17 to 21. And weights anywhere from 30 to 60 pounds. Its life span is 10 to 15 years. The pitbull terrier as he's known, is often described as a goofball or clown. This medium sized 🐕 is not always aggressive, he has a fearsome reputation because of his background as a fighting 🐕 overall it is a loyal and protective breed.
