It would be best if you considered the crate's purpose before purchasing one for your whippet. Researching the length, width, and height that your dog will maximally grow to before buying a crate is vital. Measure the size of your whippet before buying it a crate, if it's for temporary purposes. For the growing whippets, ensure that you continually upgrade the crate's size to accommodate the change. The crate must be comfortable to avoid injury. The underneath tray should also be strong enough to prevent an accident.
