I just bought 15 more of these. Our precious little rescue, Panda, was introduced to these little hedgehogs not long after she arrived at our place. It was love and obsession at first sight. These little hedgehogs are soft and can be thrown like balls. They seem to hold up very well to constant squeaking, but if your dog chews toys, I’m not sure how they would hold up. Panda hordes them and squeaks them and hides them and brings them to us to throw. We find no less than five every morning when we make our bed. Panda also loves to pull them out of their hedgehog dens. The reason these hedgehogs have to be occasionally replaced is because they get so crusty. I’ve given the hedgehogs baths with shampoo and conditioner, but I cannot seem to remove the crustiness of the older hedgehogs, so I just covertly replace them with newer ones. Most of the squeakers have lasted the duration.
