    A huge and diverse subfamily of dogs, the bone-crushers patrolled North America for more than thirty million years, before they disappeared in the not-too-distant past. So what happened to the biggest dogs that ever lived?

          If you truly wanted to be inclusive then your videos would also give measurements in standard measurements as well 😎

                The bone crushers reminds me of hyenas. Maybe is cos hyenas have large jaw for crushing bones. They are bone crushers too (not literally).

                                Hello I had a bone crushing dog name Tyson he was my service animal but was feared and respected as An Alpha Male APBT and Rottweiler Didn't challenge him. He had a vitiman A deficiency I'll say do to dog meat is high in that vitiman. He got in a fight with a person pitbull that made the dog fight my service animal and the animal control told me the report of why they put the APBT that was human aggressive and not animal aggressive that the damage Tyson did with just 3 bites was cause to put the dog down. He bit him on both cheeks and the frontalis and pulled back bone. And he did this on his back also with a LaGuard vest on 11lbs and a pinch collar with a leather spike collar also a chain leash that weighs 7lbs without pulling he protected me in which the APBT was trying to get to me and avoid my service animal Tyson that caused us to go around in a circle. They were both 1yr 6mos and 60lbs Tyson was 24in and the APBT was 26in without any restraints and a small nylon collar that's all. But the APBT wasn't interested in hurting me originally the owner forced the dog to. The APBT lost his life due to a female owner personal pride and what she thought APBT post to fight when told and that's not 100% True. It's Sad to me. Also Tyson Ate 6 dogs that froze to death do to a dope man illegally messing with DTE. Therefore he took it upon himself to clean up. Then I learned his signature and why dogs feared him and wouldn't challenge him. He ate everything but the skulls. And it wasn't out of hunger for he had food and water. email me and I'll send a pic of how he looked the dog that was bone crushing. He was a great and locally famous service dog he saved my life more than once he was killed for saving my life in 2016 by a landlord whom attacked me during a seizure and he went and got help and the person he found spoke with the landlord looking for me and the landlord informed me he poisoned Tyson cuz he brought someone to his house and disposed his body in an Abandon home so I couldn't bury him. The police didn't allow me to make a police report on which I have scars from the attack and my service animal was killed. But he's in heaven with my grandma Lee chilling watching over me.
