Tyson is one of three pups from the same litter in our home, and the one we are keeping. I named him Tyson after Iron Mike because, while the other two pups were a bit shy at first, he went straight for Odin's neck and started roughhousing and playing. No fear! He is super sweet and has gotten extremely attached to me. All three of them are very receptive to training, but Tyson seems like the best fit for our family.
