I am SO GLAD to know tha I am not the only one struggling with the toy situation.
I have a 1yr old Yorkie who has a knack for biting. He destroys -every- toy he is given. He has one ball which has lasted, and we recently bought him a big air bouncy ball which he LOVES because he can't possibly bite it, since it's round, smooth and too big, but he will chase it and knock on it for hours.
He has started chewing on his beds and has destroyed three of them already. I find myself sewing, often!
The kongs are excellent. They have lasted him the most. I will check out all the previous suggestions
Good luck!
