I am commenting on two posts from yesterday in one email. Lump under the jaw, did your vet check the teeth. Sometimes an absessed tooth can cause a lump under the jaw. Since ferrets are prone to alot of teeth issues, have him check this out also. Your ferret may need a tooth extracted. We had one come into the shelter with this issue and it was a tooth issue. She had the tooth extracted, was on antibodics for 7 days and the lump went away. Blackheads are pretty simple to get rid of. I find using stridex pads work wonders. I run the pad up and down the tail gently scrubbing the infected area. I do this twice a day. Within about 1 week you will notice new hair growth. It usually has to do with the oils in the coat and alot of ferrets deal with this issue. Almost like a human face. I am sure certain foods, just as in humans, effect this, or is the cause of these breakouts breakouts. Ferrets also go through coat changes naturally which cause this issue. Any brand of pads will do, I use the Walmart brand. Cheap and they work. Another tip is Dawn Dishwashing soap. Wash the infected tail area with that twice a day using a wash cloth. Rinse well after washing. That keeps the area clean and helps to clear up the blackheads.
