Handed out for gifts at Christmas. All the dogs liked and it survived all the chewing. Glad I purchased!

Not durable at all!
Size: Small
I have a 25 lb terrier that tore this into six pieces in about 8 minutes. They're big ones are durable but this one is horrible. Do not get this if your dog likes to chew on things.
