Can a dog bleed to death from a broken vein on their toe if the toe snaps off?
Why would a toe snap off? Do you mean a nail or claw? If it is a claw then no, it won’t bleed to death. If it is a toe that has broken off then a vet is needed. EDIT – I now see you have added toe. This has happened due to an infection in the bone of the toe. It has died and literally dropped off. Your dog needs antibiotics and the hole repairing and bandaging. It needs to be a main artery to bleed to death. There isn’t one in the toe joint. Get to the vets as soon as you can. More infection will lose more bones.
