I don't have much to add as everyone has given you great adive. We were nervous about bringin in a second dog even though Sadie was only 1 herself and loved other dogs...for a few days she seemed to hate the idea of Cincy, but after that and to this day they are inseperable! as much as she loves playing with us, there are just ways dogs play together and relationships they have we can not duplicate.

Goodl uck with your decision!
