Is There a Natural Way of Getting Rid of Flies by My Dogs' Ears?

Apple cider vinegar is a natural repellent that will keep flies from bugging your dog's ears. White vinegar also works, but your dog -- and you -- will appreciate the scent of the cider variety more.

Dogs with erect ears suffer more from flies buzzing around their ears than breeds with floppy ears that cover the ear canal. Use homemade vinegar repellent for a dog that shakes its head or scratches its ears.

Apply a small amount of apple cider vinegar to the dog's ears with a cotton ball. Don't wipe too far down into the ear canal. Wet the outside and the inside of the ear with the vinegar.

Mix 1 part vinegar to 1 part water in a spray bottle. Spray lightly around the dog's body to help repel flies and other insects daily. Rub or brush into the fur. Do not spray the mixture on the dog's face.

Bathe your dog using 2 to 3 cups of apple cider vinegar for longer-lasting fly repellent. Don't get the vinegar on the dog's face or eyes. Use a washcloth to bathe the ears with vinegar for more protection.

Add apple cider vinegar to your dog's water bowl or food each day to repel flies from the inside out. The trace minerals and nutrients in apple cider vinegar provide an added benefit to your dog's health. Use 1 teaspoon for small dogs and 1 tablespoon for medium and large dogs.

Do not feed apple cider vinegar to a dog who is allergic or sensitive to yeast products or apply it to a dog who has skin problems without your veterinarian's consent.

Organic, unpasteurized apple cider vinegar is stronger and more effective than non-organic, although both work to repel flies externally. Use organic vinegar if you're supplementing the dog's food or water.
