I have tried soooo many brands of shampoo's trying to find the "right" one for Oscar.. I could not figure why he was always itchy. His skin was perfectly pink and no flaking or reddness. I finally realized that it is the perfumes that bother him.. I can't even use grooming spray on him..I just squeeze a few Vitamin E caps in a spray bottle/water..
I called my Vet and he prescribed a shampoo/conditioner with no
soaps/dyes/perfumes.. I have been using it for this week and wow, what a difference.. No more itching and it leaves Oscar's coat silky and shiny...
It is very expensive at the vet $28.00 for an 8oz bottle but i found it online , $20.00 for a 16oz bottle.. I already sent in my order ...

Look @ my gorgeous boy.....
