This product requires proper fitting and owner involvement, Happy Tail Syndrome takes time and care to heal. The TailSaver helps when used correctly. Please review instructions before use or purchase. Happy Tail Saver Sets have 3 parts: 1. Harness which disperses naturally occuring pressure when supporting a strong and active tail over a large enough area for comfort and no- pressure points... a patented design not found elsewhere. 2. Tail-sleeve tested to not be chew worthy as long as dog's are comfortable and unrestricted... this is done with carefully adjusted straps that lock into place without risk of slippage. The tail slides into the sleeve and is surrounded by light weight breathable airmesh padding that keeps wounds safe from re-injury, dry & clean. The open-cell material doesn't retain moisture or irritate wounds. 3. An adjustable wag belt is included to provide wag control & an extra angle to the setup for a secure fit that won't come off during group play, running through bushes or vigorous wagging. Dogs go poo & pee without needing to remove it. *Instructional video (12 min.) helps ensure the dog's comfort and secure fit.
