You don't get to choose which dinosaur you get. I ended up receiving the stegosaurus. I wish I had received one of the other shapes. This toy has a lot of sharp edges, which are made worse once your dog starts to chew it up. It's also pretty heavy. On multiple occasions my dog has dropped it on my feet and it hurts! I also have bamboo floors and her repeated dropping this off the back of the couch has started to leave small divots and dents in my wood floor. The product does live up to the Dura Chew reputation though, she has been working on it for a few months and hasn't made much progress. I imagine due to it's mass it will last a long long time. Hopefully some of the sharper points will be smoothed out...
