On his under chin he has a pocket filled with a clear sticky fluid. It isn't bacteria. Once it's drained it comes back by the end of the day. It goes away with Clavamox antibiotics. It looks like he has an iguana or pelican chin.
Hi there and thank you for using Pet Coach! Judging from the photos you have included, there is quite a severe amount of swelling under the jaw. If the area has not resolved on antibiotics and it is a clear fluid coming out of the swollen area, there is a good chance that this is what we call a sialocele or this could be an abscess. An abscess, unless drained, is difficult to treat with just antibiotics alone. Most of the time the abscess needs to be lanced using a scalpel blade and the contents removed along with flushing out with an antiseptic solution. If this is not performed, there is a good chance it will not resolve. I would recommend sedating Megalodon and draining the contents from this swelling to see if this helps resolve the problem. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
