Stimulating a dog’s brain is as important as physical exercise, and using mental games will stimulate dogs in a way that properly targets their mind. Dogs must find the solution to the “puzzle” that is proposed to them and, since we offer a reward that they really want, they will try their best to find the solution as quickly as possible. Proposing these activities to the dog also involves physical benefits, as the dog will get tired as if he/she had done physical activity. It is an excellent solution for elderly dogs. The dogs understand when they solve a brain game, which will increase their confidence.
