I give handouts to all my in-home dog training clients and at the end of one of my handouts is a list of some dog toys. One of my favorites is the tricky treat ball.
I use the tricky treat ball with my own dog. I fill the ball with some of my dog’s kibble every time she eats dinner. She really enjoys it, she gets mental stimulation along with some physical exercise. The ball has one hole in it and all I have to do is put some dinner kibble in it. Treats can also be put in it as long as they are small enough to fall out. My dog pushes it around with her nose or paws and the kibble falls out. It is a great way to give your dog something to do. A lot of pet supply stores sell them or you can buy it at
