Mental training is great to keep your oldies dog's brain working. Just like with humans, the more active your pet's brain is, the better off it is and the less likely it is to "go south". Furtherrmore, if your cat gets bored, he is more likely to develop a destructive behavior than a positive one.
There are a few exercises that you can do to keep your pet's brain entertained. For instance, you could try:
- Giving it new toys to play with and exchanging them with the old ones;
- Engage your dog in a Dog Memory game or Dog Dominoes;
- Run small errands with your dog (go to the mailbox, stop at a friend's house, etc.)
You could also introduce your dog or your cat to new faces (but taking it to the park for example). This will keep its brain active by stimulating its senses, as it will discover new smells, new sounds, new butts to sniff, etc.
