Excellent for sensitive skin

November 16, 2022 | Gian Algieri

Purchased the shampoo for our Westie. Have washed him in the shampoo- time will tell if effective.
The ordering online did no go very smoothly however. I received the invoice but no confirmation of despatch. I had to telephone Groomers after a week for confirmation. The gentleman who answered informed me that it was despatched 5 days earlier and he would chase up FedEx and re contact me as to status. Did no receive a feedback telephone call but luckily chased up FedEx locally.

Excellent Product, My best mate has gone through the dreaded scratching,could not pin point way! So gave him now two good baths over ten days using Groomers Medicated Shampoo, what a lovely product to use. Easy to work into his coat and very easey to wash out, Leaveing a squeaky clean finish. His coat looks and feels fabulous and the scratching has stopped.
