Have heard throughout the years that putting a drop of Frontline spray in a ferret's ear was safe to get rid of ear mites. Has anyone heard different and why? If it is safe I would like to know how it's used and if there needs to be a second dosing. I can also get the oral ivermectin but know that take quite a few dosages. Thank you for your help.
