Trixie Aloe Vera Dog Shampoo

My dog developed what looks like a hotspot within a week of using this shampoo. He's never had anything like this before and when I read another reviewer mention what sounds like exactly the same thing it confirmed for me that the shampoo is the most likely cause. I'm using coconut oil and homeopathy to clear up the area of irritation and I'll be returning to all natural basic soaps from now on. The Trixie shampoo is going in the bin!
