After reading some reviews for Angels Eyes, I decided to try it. Bad decision. My shih-poo won't eat it when I mix it with yogurt like I did Angels Glow. Also, it doesn't say anything about cutting back on the dosage once the staining has stopped. I was only using the Glow every third day. It made a nice paste when mixed with yogurt that Harley would eat right off my finger. After reading more reviews, I'm going to order Tylan Powder (it's the main ingredient in both) and try it.
