Slept with my dog a day ago and didn't notice until she bled all over my mattress, blanket, and pillow that she was on her period. Will I be safe sleeping in a bed covered in dry dog blood if my dog doesn't have any infections or diseases? I seem fine so far, and I've slept a whole night in this bed after it was covered in dog blood already. The reason why I haven't cleaned anything is because I don't know how and I'm lazy. PR is not my bed.
