Hi Annie, I thought some of the people on here stuff some of the toys with peanut butter and their dogs go crazy over them, roll them around and try to get it out.
I tried one of those toys with Daisy and Perry, I put some of their dry dog food in it, they were lazy wouldn't roll it around, waited for me to do it for them, then Daisy decided to guard the toy and wouldn't let Perry near it so I gave up.
