I am a terrible product hound. I have spent a small fortune on dog products. My daughter is an assistant for a top toy handler and makes fun of me for spending so much money on dog products. She says "you owner handlers waste so much money". She uses Assie Moist or Pantene on our dogs. I will say, on days that I show, I use Ise of Dogs Vet Grade Shampoo and Building Conditioner because it makes the coat look better but I don't see the need to use $27 bottle of shampoo for weekly bath. I use a whitening shampoo every six to eight weeks and I really like the new Pure Paws Magic White.
I think water is just as important as the shampoo you use. I use distilled water to mix concentrated shampoo and to rinse.
I use it and love it. HOWEVER...they changed the bottle to a purple and sicne then I don't like it. Luckily I found an extra bottle of the old stuff under my sink and have been using that and love it. The old bottle was white. idk if they changed the formula or not, but I stopped liking it.
I use loreal (sp?) kids tearless shampoo 2 in 1 (with conditioner, watermelon scent lol) and then use a bit of the aussie. Make sure you rinse WELL tho. I also mix my own shampoo with essential oils made with castille soap, but I find it strips the natural oils, so I use it once a month as a clarifying shampoo of sorts.
