Chase had a very ruff start to his little life. Not only was he was close to starving to death but he also suffered a major break in his back femur. The leg healed crooked and then encapsulated the knee joint fusing everything together. Chase is a strong happy boy and he can still zoom with all of his big and small foster siblings. He loves everyone he comes to meet. Chase hasn't been tested with cats yet and he likes to chase small dogs but will not hurt them. We do not recommend small animals. Chase's leg sticks out making him a trip hazard so we do not recommend he go to the "gravity challenged " either. Chase thinks he is a lap dog and he will crawl up on the couch or bed to get in his daily/nightly snuggle time and belly rubs. This is a non negotiable requirement . Chase just reminded me that Pool time and/or lake time is also a requirement.
