Yup he is a mosaic just like my lil guy. Like they already mentioned, keep him entertained...do you have a wheel. And definitely lots of chew toys. He was probably really stressed at his old home. My friend has a beige chin who was a fur chewer when she rescued him. She definitely made his life 1000 times better and he has become should a pretty and especially grateful chin. He is so happy now she literally can pick him up without a hassle and even have him sit her on the couch (but she's had him like 3 years now). Point being, there's a chance he'll get better!
