Loki (spoo) and Rosy (cockapoo) love the lambchops. Unfortunately, Rosy destroys them. PetSmart had spring ones out, but they are currently out so I can't replenish them. I also recently bought Loki a Nerf gun that shoots little balls. Despite the fact that he is a 45lb spoo, he prefers small toys and small balls. The range on the Nerf gun is adjustable so I can use it inside. Loki does not like his precious Nerf balls to touch the grass and get dirty.
