Dirty and all alone Bailey took him back to Horseland to try and find his owner. Since no owner was found Bailey adopted Cubby. Cubby looks up to Shep. Angora told Cubby that he'd been causing trouble ever since he came along. Feeling upset Cubby runs away. The gang goes looking for him. They find Cubby and take him back home. By the end of the episode Alma accepts that Cubby is Bailey's dog. She takes Bailey up on his offer to help him take care of Cubby. Shep learns that Bailey has a big heart and that there's enough room for both him and Cubby.
