My Sierra had Sarcoptic Mange when I adopted her and didn't know it at first. Both my husband and I had the little critters on us too. They were most active on us late in the evening and mostly around the waistbands of our pants or the top of our socks. Where ever your clothes are the tightest to your body.
My vet asked me to keep her in the car until they were ready to see her and when they were ready for her to come in they asked that she be carried into the exam room. Your dog does not have to be in close contact to another dog in order for them to spread. Please leave Daisy in the car when you go to check into the vet.
My hubby and I didn't have to do anything to get rid of them on us, they can't live on humans and die quickly.
Off the top of my head I can't think of what my vet gave me to give to Sierra..... I know it was just a topical application. It might have been Revolution. No pills or injections.
