I have purchased a ton of these to just have around to replenish toys for my dogs. I have three large dogs that love to destroy toys and they love anything that any toy that is soft and fabric. They play with these all day and usually destroy them the same day because they gnaw at the seams. But they are only $1 so I can afford to keep a lot around and keep them occupied. Dogs love them and the price is right!
It must be the texture or feel of the corduroy material that these are made of because all of my dogs, big and small, go crazy for these! They love them and I think they are pretty durable too. They seem to last a little longer than other thinner material.
