I have a 17 month old scott type american bulldog. she was about 21.5 inches and the withers and almost 51lbs at 6.5 months. she is now almost 24 inches and about 63lbs and she hasnt seem to put on any weight in the past few months. Ive only seen pictures of her parents and then seemed big. her mom very tall and slim her dad big and very muscular. the breeder said she should be at least 75lbs but said she would be big more likely in the 80-90lb range. she is still kind of thin but i've noticed that recently her chest has started to become wide and shoulders very muscular.will she reach anywhere near 90 or stay like she is now?
