Well my 1 1/2 year old doe had a tumor. It steadily got black in the middle till last night it popped. She now has a nice size hole in her belly. What can I put on it that isnt toxic but will help keep out infection? I am leaving for a week in abut 2 days. I was hoping too just leave them with enough food and water but now Im worried that this hole might need to be taken care of daily. Please help! All advice GREATLY appriciated!
