My husband and I have a hyper 2 year old GSP who is 55 lbs and a Lab Mix puppy and they love all animals! We keep them active on the weekends hiking, boating, and going to the park. If your dog is not aggressive with other animals, we would love to keep him busy. we have a medium size fenced in back yard but have many places to go and run. We love animals and make pets part of the family. Before having our own fur baby, we did house sitting for friends and relatives to keep their dogs. Now we are married and invite fur guests to our home. If you have any questions, do not hesitate to ask. We look forward to working with you and your pet.
