You know! Like chew toys, squeaky toys, tug o war ropes, balls with little bells in them.
I personally have a squeaky toy shaped like a news paper, a stuffed sheep that makes a "bahhhh" noise and a blue tug o' war rope.
Yes I do chew on them, as though by instinct and I find it fun. While I'm lying in bed and lay on my stomach and chew on one of them for a while before bed. It brings out my inner dog.
So, you have any chew toys or any normal things that you chew on/play with? X3
