Durable and they love it!! She usually follows me around everywhere. She is like velcro, but after I gave her this, she stayed upstairs with it and didn't come down with me. This isn't your natural rubber either, this is very thick and durable, which is important to us because we have Boykin Spaniels who are so hard on toys, they call them Destroykins. I also like the fact there aren't places where they want to chew so they can rip parts off. Nothing is sticking up off of it. This toy was way more than I expected!
