I know that it is annoying - my kitten did the same to my DE thames a few years back - but now that he has grown up I actually smile every time i see his little teeth marks (cheesy - I know ). I honestly think that as patina develops the bite marks on your delightful will become much less noticeable. I'd spend your money on something new and exciting and keep loving your delightful with it's personal touch
This brought a smile to my face, I have a 80lb black lab and I love him to bits, pain in the *** though, but he brings such enjoyment to our lives.
