Hello I need some advise. I have a pregnant Arabian Mare and I've had her since January. The people I bought her from had some really wonky halter on her saying that she always scraped her halters off. And she rolls in the mud DAILY. Now that she has shed out her summer coat she has there scabby places on her coat, one on her neck and under both elbows where there are scabby sores. I started picking at the scabby places and found BUGS!! Big black ones that look like giant black fleas! They must be some kind of lice I suppose. My querstion is what pesticide is safe to give a mare that is pregnant and due to foal in November? I'm assuming that some kind of dip is the answer but I don't know which ones are safe and what exactly she has.
