This is a size L harness to assist small dogs and dachshunds with walking. I tried it about twice, but my dog didn't like it and wouldn't walk, so I stopped using it. It's quite sturdy, so your dog might have preferences, but since it's hardly been used, it's in good condition. If you'd like to try it, please consider it ⭐️ - Brand: LaLaWalk - Size: L - Intended Use: For small dogs and dachshunds - Features: Walking assistance harness Thank you for looking.
