We really get a hang of what toys and treats really keep our dogs occupied, and in this case, challenged! I really love Canine Genius’s Leo treat release toy. Every time I give one to a dog they go straight to work, I can really see the wheels turning as they approach the Leo and figure a way to get the great smelling treat out for their enjoyment. If your dog has completely mastered this brain twister, you can connect several toys together to create a treat maze even! Canine Genius has IQ Treats to specifically go with this toy system and our dogs really love them. One of my other favorite things to do is to break up sweet potato and chicken treats to put inside, this really gets our Australian Labradoodles thinking!
