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.

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