Healing for a head injury usually requires restrictive activities, which can be boring for your dog. As a pet owner, you want the best for your pooch so engaging their minds is a great way to burn mental and more physical energy while stimulating their intellect. Scent work is a perfect way to engage a dog because their noses are so sharp. Scent work also helps build your dog's confidence and will occupy their minds while they heal. Scent work activities for healing dogs occurs mostly inside where you can control the environment, so the weather does not play a role in this activity. You will need three or four small cardboard boxes and one plastic container that you can cut holes into. Additionally, you will need some smelly treats that your dog can identify. It's best if these are your dog's favorite treats because it will serve as additional motivation during the scent work.
You can teach your dog and work on some simple tricks like nose licks and ears up. These are not overly active tricks that require a lot of energy, but they are mentally challenging for your dog.
While your dog is on restrictive activity, you can practice settling techniques. Settling is not exactly a trick but a training exercise where you dog learns to calm down and settle on the floor.
