Winslow has one of those bottle crunchers - loves it! Had it over a month and it's only beginning to come apart now, but it wasn't a very sturdy material like I'm inclined to suggest to you but I think your Chesty might like that.
I'm not sure what else... He had a Kong squeaky toy on a rope, so far it seems to hold up well. Good luck! I love buying him toys, I'm pretty sure I buy more for him than I did for my daughter when she was a baby
