1. Kong Toys: I love to fill these with large treats or kibble that barely fit through the opening. These are great for chewing and chasing. 2. Filled/hollow bones: when these are filled they're a fantastic temptation! When they're empty I like to smear peanut butter inside, maybe add some kibble, and freeze for longer play time! Really great for long car rides. 3. Cow hooves: these have a great scent for the dogs, and I also love to put some peanut butter in and freeze. They are great for the dogs teeth and soften as they're chewed on, so I find they're good for dogs that don't often like to chew on hard toys. 4. Jolly Bones: these have been SO durable! And they float! They're great for chase, tug, and chew. 5. Tug rope: these should only be for play or training and not for chewing. They are fantastic for play, rewards, and tricks! All of these are great for mental stimulation, and can be used in conjunction with regular training practices.
