What are some fun activities to keep my senior dog happy?

It's about having them interact with you. Many times, it's getting them up and moving and going on a walk at a slow pace where they can still get up and move and enjoy that time. If they love to play fetch, do that. They may not be able to go the longer distances anymore, but having them up and active with you is good to have them doing well in their later years.

Senior dogs just want to be with us. If a dog is used to getting a daily walk, and he's at the age of 15, 16, or 17, he still wants to go out, sniff around, and feel like a dog. So making sure that he has those things to stimulate his brain and give him a high quality of life is really important.
