I bought the Tux at my local pet store with skepticism. I had been recomended another brand previously and told it was THE toughest(I think it was made out out tire material)that it stood up to this person's pit bull mix with flying colors. My labrador destroyed the other brand in one day. I am happy to say the the Tux has lasted over a year and I fill it with peanut butter and freeze them for my dog to enjoy. She loves it and so do I! Fantastic product, thanks West Paw!
