When I was a wee little one, momma bought me a purple squirrel (kong type) toy. She had been searching the interwebs to find good treats and combos to fill it with and came up with a treat, bone, peanut butter concoction. When momma left it for me while she went to work I wasn't interested. So I just left it alone. Momma was sad she thought she found a great treat combo for me to make my kennel time less stressful. So she returned my squirrel. She just hid treats in the bedding for me to hunt and find.
