Should My Dog Bleed After Mating?

This may occur, especially if it is a female and the first time it has mated. Best to keep an eye on the animal to make sure she or he is fine. Though I cannot see a male bleeding in this process. If you are concerned, get them to a vet. But wait and see how they are doing first, maybe give it a day or two, if they are not acting as usual and seem ill, best to get attention for them

They don't go out of heat after the tie and can mate many times and even with different males. If the tie was interrupted or anything like that you should see your vet as that often causes hemmorrhage in the female. So still being in heat is normal but a change in the bleeding probably isn't or if something might have happened during the mating. If there is anything you are actually concerned about you should probably see your vet as a clotting disorder like VWD is always a possibility as well.
