Peanut butter, wet food, pumpkin, plain yogurt, dehydrated meats, carrots... Other random things I think they may like.
They last a good 45 minutes or so. But I always get a nap out of them! :rofl1:
Everything but the pumpkin is pretty fattening though, so I tend not to give them too much as I have a Fatty Peanut Head, ie Rider, who gains pounds like his mom.
