They say you can’t teach an old dog new tricks but I’ve never believed that and now researchers are studying cognitive function in older canines. They are using brain games to see if the cognitive function of the dog can be increased leading to overall better mental health for the older dog. While most people won’t play actual brain games with a dog it is very simple to stimulate their brain. All you need to do is take your dog outside and spend time with it. If you can go for a walk in a wooded area with wildlife then that’s even better.
