Doggy medications

Hello everyone.. its the time of the month where i am running out of meds for my dog Sir.William, and need to get more. Sir.William has a rare skin condition called sebaceous adenitis, in short it causes his skin to grow in clumps and fall off, it also affects his immune system and he becomes susceptible to staff infections, which he is currently on antibiotics for now. Anything you can spare will be greatly appreciated thank you!
