Gordy and I play hide and seek A LOT in the winter. I just ask him to stay in a room while I hide in another. He loves it... and I love when I hear him get the zoomies when I say he can come find me!
We also do a lot of puzzle activities, and things that will make him use his nose!
There are indoor swimming pools in our area that I have started to take him to since it is cold, and swimming is one of his favorite things, so we have a blast!!! Also, it is good for him now that our vet suspects that he has hip dysplasia, I have just been making sure he uses the ramps to get in and out rather than jumping in, so that we can save stress to his joints.
For a lab, Gordy is very easily contented and exceptionally calm. He doesn't like cold weather walks, and is just happy to curl up next to me and settle in for the night once I get home from work. He's such a good boy
