You can use pure aloe vera juice and try adding lavender and / or peppermint essential oils or fresh squeezed Lemon juice and spray or pour over the dog after a bath.
Mix 1 teaspoon of raw organic turmeric powder with 1/4 cup of raw honey (Manuka honey would be the best), and purealoevera gel, or fresh lemon juice and make a mask.
Definitely stay hydrated — I drink aloe water, which you can either make with purealoevera mixed it with water, or you can buy it at Juice Press or Organic Avenue, but not everybody has those conveniences like we have in New York City.
