Our mini Schnauzer has a few 'itchy' spots that she won't stop licking. We have spent a lot of money on sprays to get her to stop. This seems to work as well as expensive sprays.
1/2 c apple cider vinegar
1/2 c green tea cooled
1 c distilled water
Mix all ingredients and put into a spray bottle. Spray on the spot that bothers your dog.
