Query: Amazing!

This collar has been great! We've had it for years and it still looks brand new! They swim in it and we've had no problems. It bleeds a little, but thats not a problem. We were looking to get a new one for my other dog, but sadly I can't find it anywhere online :( It's too bad because it's difficult to find such a high quality item for the price.
