Mom was looking at a newspaper and there was an article about power lines and keeping them free from raptors, and having watched Jurassic Park one too many times, I think she was thinking Velociraptor - not the bird of prey common around here because she then made this sign to go up at work.
It's a Nylabone Dental Dinosaur! It comes in brontosaurus, stegosaurus and T-rex (one is chosen randomly). I asked if it came in "Barney" and Mom said the stuffed Barney met with an industrial accident after she watched 20 episodes back to back with the little peeps.
Mom picked this one because it's made for "powerful chewers" and she says I could eat a Humvee in 15 minutes if it had a squeaker.
Mom finally took it away from me, to give back later, as she says such toys should be only used while supervised, and then it was time for dinner.
The dino held up well. This large size was recommended for dogs up to 50 pounds. I'm a Lab MIX and am a lot smaller than most labs but I'm still a bit above that limit so Mom just let me play with it a short time, closely supervised, then we put it away. But with 20 minutes of serious, solid chewing it had only the tiniest of scratches on it and none of the pointy bits were broken off. I would certainly recommend it for your medium sized dogs for fun and Mom would recommend it for dental health. They also make a smaller sized dino.
