Absolutely love this product, the almost immediate effect of this product really shines above the short lasting odor from it. Got a puppy 2 years ago, he had hair missing from his face, neck, shoulders. I initially thought it was a food allergy, but after switching his food and no results plus constant scratching I had a skin scrape done and he was posi for demodex. We did ivermectin for a short period of time before I found the dip, but the cost of that with a growing puppy was just obnoxious... constant vet trips no results as he practically outgrew his dosage in a matter of two days. I nixed the vet and went with this and it was fantastic. He looked better in the first week, stopped scratching himself apart. I intend to keep this product on hand just in the event I need it for him or anyone else again.
