Likewise, the K9 Top Coat is perfect for dogs with allergies. It is used to cover hot spots due to licking, biting, and chewing irritated areas. We have had well over one hundred dogs use the garment for allergy control. There are a number of reports that numerous medicines (including Cytec, Benadryl, Prednisone, and Cyclosprin) have been ineffective. Yet, the K9 Top Coat worked wonderfully. As a result, we are currently studying the effect of the garment on various skin conditions. To date, we do not have a specific objective reason that the garment is effective–only that it often works much to the relief of the patient and their owners. However, we are confident in the garment and encourage vets/owners to try the garment on their most difficult cases.
