Since my last reply on this, I was giving Cody his nightly "check up" and for some reason lifted his upper lip and noticed 1 front tooth was smaller than the other and another chipped. He's been smacking his lips for 2 days. Off to the vet tonight. I think his teeth get stuck in the knots of the rawhide and he pulls. I always supervise him-actually, he'll only eat it in my presence. He's not been eating the rawhide, but carrying it around and laying next to it. Now I feel as guilty as hell and I am so worried about his gorgeous teeth. I'm glad he's NOT eating it but my heart is pounding from worry. He already lost a tooth years ago so I hope they don't need to be pulled. He'll be like a little old man with no front teeth!! Plus the discomfort!! Jesh, now I made myself sick! My poor boy!
