My small dogs enjoy challenges, especially food-related ones. To mentally stimulate them, I made this dog toy them instead of buying those expensive 'intellectual toys'. They have fun with it so I hope your pet does too:)
Prepare a small size plastic container with cover. Wash those thoroughly and towel-dry.
Using a pen, mark the container. Then, punch holes on the marked areas using a carving knife. Make sure that only a single dog treat would pass through the holes.
Note: Use a dog treat to determine the size of the holes.
Put several bits of dog treats into the container and put the lid on. Give it to your dog; put the treat dispenser on a surface and see how your pet extract the dog treats out.
