WTF has Red Leg

[monster]

The only other treatments I have been able to find is a super quarantine and total breakdown and cleaning of what hes in. I guess unless hes still in quarantine. And if there is open sores to put the polysporin without pain reliever on the open sores if there is any to prevent secondary infection. The drug you have is what they would give him, that or enrofloxican ( baytril) for him to bath in. If you give him this do you know how much to give him according to his weight?
