I need any suggestions for durable plush toys for my 2 savannahs. Our one boy is teething so he's chewing on everything he can and our other boy is just a hard chewer. We've tried rubber toys but they seem to only like plush realistic ones. We just got them a large tuffy toy that are made for dogs that are hard chewers but they've managed to rip the seams out and are pulling the insides out like always. Thanks for any help! My shoes and I will thank you.
