I just adopted a pit butt from one of our local shelters, and she had happy tail syndrome--she had literally beat the tip of her tail to a pulp against the metal of her kennel. She tolerated bandaging really well, but at some point, it would pop off because the tape doesn't hold for that long. If I caught it quickly enough, I could get it re-wrapped, but if not, one good whack undid all our progress. Her tail is a lethal weapon, and she is one of the happiest dogs I've ever met so it's going all the time. Then her tail became infected, and we really wanted to get air to it, but she needed protection. The TailSaver has helped us turn the corner. She had zero issues with it, and I didn't have any trouble fitting her after watching the video a couple of times. She's had it on for just over 24 hours, and the tail has already scabbed over nicely and the sewlling has gone down. (She's also on a high dose antibiotic, silver sulfa creme, and some pain killers. Without the added protection of the TailSaver, though, I don't think those would be as effective. It's absolutely part of the cure.) I highly recommend these and am very happy I bought it. The shelter had one of the cheap versions on when I picked her up, and it had already chafed the insides of her back legs badly. I had an appointment with my vet immediately after bailing her out, and we took it off and left it off. My only regret is that I did not buy this immediately--she was so good about the bandages that I thought she would heal without it. Wrong. Once we get through this, I'll wash it and tuck it away, just in case. Thank you for providing such a fantastic product.
