Hi, you can use a 2 in 1, it is probably a good product, I don't have any experience using that product. I use a tearless puppy shampoo with chamomile and oatmeal, and then rinse my guys really well, we installed a hand held shower head on our shower to make it easy to bathe and rinse them. Then I do a second rinse with apple cider vinegar mixed with water. One part vinegar to 3 or 4 parts of apple cider vinegar, and then pour it over your dog and rinse off. This is really good for the skin, and leaves their fur really soft and shiny, plus I find they smell fresher longer in between their baths.
