Do you have a dog destroys crates? Does your dog have signs of severe separation anxiety? We have specially designed this crate for those puppies with special needs. The high anxiety crate is a stationary crate that is shipped assembled. This crate is welded, riveted, and made out of a higher gauge aluminum. The air holes are designed to help prevent most dogs from damaging their teeth if they try and escape from the crate. The front door bars are closer together to help prevent your loved one from biting the door.
