He is a 2-year old cocker spaniel mix who weighs about 15 pounds. He is a very sweet and happy dog. Casper will only be placed in an adult only home, no exceptions. He gets startled by quick and sudden movements so he needs a quieter home atmosphere. He was in playgroups with other dogs and he can be a bit dominant but overall did well. He might be able to be placed in a home with another dog, but it would depend if the other dog is on the submissive side.
