The dose is approx 0.37mg once daily. I've been applying it to his lower back. So the big lump that he cut into had been there for a couple days before I became concerned. It was firm but didn't appear red or painful. I took him out to clean the tank and I noticed that it had ruptured? I pressed on it with a moist q-tip and a small amount of white fluid came out. The Dr said that he found a little more of the same fluid but nothing else. The wound is almost healed but it's still a firm lump but no more discharge. The other lumps are on his back legs. They are small with a dark center. Those come and go but recently one has become larger and more white. I've stopped the antibiotics. What do I need for a hospital tank? Just moist paper towels in a critter cage? And no they didn't do histopath.
