I had a ferret who had the same thing happen following a Deslorelin implant. His carrier looked like a masacre had taken place by the time I got him home and so I turned around and took him back to the vet. The vet was eventually able to stop the bleeding by reapplying surgical glue to the site, but it took a while. I kept him in cage rest for a couple days to make sure it wouldn't start bleeding again. We never knew for certain why it happened. It never recurred. I lost him the following year to pancreatitis. I am wondering whether there is some major vein in the scruff area that if hit with a large enough needle, like those used for implants, could start bleeding this way since the 3 cases mentioned all involved an implant i.e., melatonin, microchip and deslorelin?
