Calvin, a young American Pit Bull Terrier mix, is a neutered male. He has a short, white coat and pale green eyes. Calvin is a high energy, playful pup. Calvin can be domineering around other dogs so we recommend he be the only dog in the house. If you have another dog, a meet and greet is needed. Because Calvin came to us as a stray, we do not know how he is around children or cats. He can be found at the Venango County Humane Society, open 12-5 p.m., Mondays through Saturdays.
