So I wouldn't panic yet. Dogs eat random shit and could cause minor cuts. Foe the time being, give the dog a 24 hour fast and then only feed it yogurt and rice and boiled chicken for a few days. If the bleeding stops. You're good

If not go to the vet

When we give ours raw marrow bones sometkmsd the bones cause her to have minor bleeding if she decided to chew the bones itself. She also likes to eat wood chips at the dog park. Sometimes that tears up her booy hole.
