A while ago something like this happened with our dog at a park. The whole claw just snapped back and was bleeding a lot without coming all the way off. I had to cut it the rest of the way off (which was something of an ordeal) and then managed to stop the bleeding and get it bandaged and wrapped up. It's taken a while but her claw is now visibly growing back out.
Thanks for sharing and I'm glad Max is doing ok.
Thank you for your comment its an awful experience isn't it. Hopefully it should never happen again
as you say there is a lot of blood which is more alarming but the cornflour really helps for it to clot and stem the flow.
Max is doing ok I think he has pain today so he is feeling sorry for himself, I am keeping an eye but it looks nice and clean. I am such a worrier if one of them is sick or injured.
