"“I just wanted to drop you a note and tell you (again) how amazing the Kennel Koff is. I had two dogs mysteriously come down with “the croup” about 4-5 days ago, and I immediately began treatment with the Kennel Koff. Thankfully, I had just recently replenished my supply with the two additional bottles. I not only treated the two initial “hackers” and two subsequent ones, but I decided to try to prevent anyone else catching it (there are a dozen more dogs in that “pack” in the house) by giving them a dose just once a day. So far no one else is coughing and the ones that were, aren’t. The first one to start was hacking so hard the first couple of days that he was “tossing” his food, so you know how bad it was. It was almost immediate quelling of the cough with the use of the Kennel Koff. I love this product and recommend it to all my rescue associates!” "
