I have made it so that there are times that I hold the chews as they gnaw on them so that they know that I am in-charge. Sometime, when I no longer have time to sit with them, I take them away and put them up; other times I allow them to keep them. I also mess around in their food bowls periodically so that they understand that a hand may come close to them when they are eating and they are not to bite. Has worked so far. "No, bite" are also words they understand. Good luck with your 5 mo. old furbaby.
They are always testing us, aren't they.
