That’s good! And it’s a type of biothane. I’ve found it to quite durable so far even when we were really active hiking and playing with other dogs a ton. We don’t do that as much now but it still held up. The only time I’ve replaced one is when he outgrew and then just a few months ago when I decided the flaky gray was ugly

but I still have that one and it’s still in good shape. He’s 2 1/2 and I only replaced it like twice in all that time if that helps. And that’s only cause he outgrew one and then again when I decided the one was ugly. These ones are designed for working dogs like hunting dogs and stuff so they’re quite durable.
