Natural dog Shampoo

This one is not edible but it was so good, it needed to be shared.
One of my dog (Bull arab X Bull Mastiff) was suffering from dry skin. He was permanently scratching and looked bothered.  We changed his diet, gave him Organic Flaxseed oil but it wasn't improving.
We (as a family) try to limit our chemical use and replace as much as we can with natural products. So we thought we would look into a natural shampoo to help our poor pooch.
Here is the recipe I used (apart from Tea Tree oil as I ran out of it):

Dog Shampoo (dry skin)

Ingredients

        2 cups of water (or infused Camomille tea)

        1/2 cup of dishwashing liquid (I use the Earth brand)

        1/2 cup of white vinegar (skin PH)

        1/4 cup of Aloe Vera gel

        1/4 cup of Glycerin

        1 tsp of Tea Tree oil

        6 drops of Lavender oil

How to

Mix all the ingredients together.

Wet the dog first. Rub some shampoo onto the skin and lather.

Rinse thoroughly and dry your lovely smelling puppy.
