Here are some exercises to keep your dog’s mind active and stimulate his intelligence:
Find your food: Instead of serving your food on a plate, hide small piles in different corners of the house or yard (consider that they are not dangerous places where you can break something or get hurt). It will stimulate your mind and develop your sense of smell and search ability.
Find your ball: Hide your ball in a place accessible to him and then ask him to find it. The first few times you will have to orientate it a little and congratulate it when you find it. A few repetitions will understand what the game is about and you will love it.
Take the croquettes: Use an empty plastic bottle. Remove the lid and put a fistful of croquettes inside. Then give the bottle to your dog and you will see how much fun you are trying to get the croquettes inside.
