I do not use people shampoo on my pups....it tends to dry their skin and hair because of the higher pH.
I have used Pet Silk shampoo and conditioner
Index and I was happy with it; but recently started using the Tropiclean line and honestly think I like it better. They use all natural ingredients and organic extracts.
I would go with the aloe or oatmeal.
Their berry scent is wonderful! I am very happy with the results...I have a couple of pups with allergies and they are doing great!
Another thing to look at is what you are feeding her....grains can irritate the skin. There is a lot of information on YT about different dog foods.
Good luck!
