My friend’s dog suffered from that terrible pink colored flee shampoo. Not only did it hurt him to apply it, but he started tearing his fur out. All of his skin turned bright red after 5 days of use and he suffered from hair loss. I asked him about the shampoo and we looked it up. Threw that crap straight in the dumpster. A good oatmeal bath helped but the suffering was terrible. No dog should ever suffer through that.
