Walter had demodex mange awhile back… it started as one spot, and we did the ointment. And then the spots began to grow… so we decided to go w/the dips. I was a nervous wreck about the dips, but he actually tolerated them very well. We also use Advantage Multi as our heart worm & flea repellant. It has actually been shown in studies to help w/mange. So far he's been fine… NO more spots. Good luck w/your baby!!!
