We have owned our 11 year old dog (40 lbs) since she was about one year old. We also have a 15 year old cat. Both pets get along with each other and with other dogs very well. We are empty nesters and walk our dog daily in the neighborhood and at the dog park on weekends. We have a nice back yard with grass and solid fence. We would love to introduce our dog and cat to your dog to see if they are a good match.
