I like to use Dr. Bronner's Castile soap. It can be diluted and it's all natural. It comes in many fragrances. If the girls are itchy then I use Peppermint. It also comes in Tea Tree, Lavender, and many other fragrances. Here are a couple links.
Do NOT use Pennyroyal on pregnant bitch without checking on this: I was taught that it is an abortion agent on some doses.
Do not use Tea Tree Oil on dogs prone to seizures. Boy did I find out that the hard way with one rescue, only I wasn't sure until I read it. Some folks say Eucalyptus oil also brings on seizures in some dogs.
Haven't checked my facts, as science and wives' tales change, but my dogs want to go out NOW. Just be careful..
As the owner of a grooming shop, I'd like to pass on that Dawn does NOT kill fleas...it paralizes them temporarily!! This also goes for all other dish soaps.
I buy the Murphy's by the gallon...cheapest dog shampoo ever. I love Murphy's and will never use anything else on my dogs. It has citronella in it as well so does repel fleas, flies and ticks. Love the smell of it too..... Best part is it is 98% natural!!!
I like the Earthborn shampoo for everyday use but the best is the Murphy's recipe. Also Walgreens sell a cake hair soap that I like for myself as it does not strip out the natural oils, cannot remember the name of the darn thing but it is in cake form in a tin.
I would also recommend looking at the MSDS for for Potassium Hydroxide-while this product is not 100% potassium hydroxide it does contain a fair amount of it in its ingredients.

I realize lots of people use this for their dogs, but No Thank you for my dogs.
Potassium hydroxide isn't really dangerous in this formula. It's used in place of lye (sodium hydroxide) in soft or liquid soaps to "saponify" the oils. Lye+oil= hard soap. Potassium hydroxide+oil=liquid soap. Once the saponification process is complete, there is no free potassium hydroxide left- it changes the oil and the oil changes it, and together it forms soap.
I looked at the MSDS. It doesn't look particularly dangerous to me. Of course you wouldn't want to leave soap or shampoo in your eyes or on your skin. It recommends flushing the skin with water after contact, which is a normal part of a bath.
Still, as a soap nut, I prefer Dr. Bronner's to Murphy. It's good stuff!
Lovely old Mane and Tail for my guys when they need it! Cleans them, smells good, doesn't strip the oils and cheap!!! With all the field work and traveling my guys do they can get filthy...especially with the variety of water they get in during training and tests. Used it for years. My young dog goes right from the field to the bath to the show ring.
