Is it possible for a female dog that has been spayed to have a heat cycle

Yes and no! If Arrow was spayed recently (in the past few weeks) and was about to go into heat sometimes the hormones stay around long enough for one heat cycle. Occasionally ovarian tissue is left behind or there is extra tissue that can then cause a heat cycle. It’s also possible that she has bloody discharge from the vulva due to a urinary tract infection or bladder stones. I would recommend seeing your veterinarian. They might recommend collecting a urine sample or obtaining a sample for vaginal cytology to see if it looks like Arrow is truly in heat.
