Male or female? Female tend to rip and tear to make a nest, more so when they come into heat. My 4 year old lab sleeps on hard plastic because what ever we put in her kennel is bits and pieces as soon as we leave.
Friend of mine had three diffrent Ameristeps. Every time one blew away he would buy a better one. Not sure if any of the three are still in this state, but pretty sure it was because of how he would anchor it down.
