We've added to our critters. Meet Zeus. He's a five month old Boxer with huge feet. If he grows into the feet he will be close to 100 lbs. by my estimation. Our other dog, Greta is a female Boxer and probably weighs 55 lbs. She is five years old and seems to be happy to have a playmate. Although he is already about her size, she still is the boss and lets him know it. X.
