    Personally, I’m a minimalist formulator so I’d start with only ingredients proven to be effective. (ingredients 1-8 + 13 and maybe 14). Then you could add some of the other ingredients to see if you get any real benefit from them.

    But that would have no antibacterial or keratolytic effect without the SA?

    Off topic, I would ensure that you get a proper diagnosis of the skin condition by a vet. Veterinary Dermatology (yes, it is a specialty, I have such a client) is even more difficult than human Dermatology. I had a general Vet misdiagnose an allergic pruritic condition for several months until it was properly treated with an oral antihistamine. It cleared up immediately after we established a loading dose with the anti-pruritic treatment.
    Animal Pharmacology is a vastly different animal than the Human Pharmacology I learned. So very different in elimination and the subsequent toxicities which can occur.
    Not a reflection on the Original poster who is experienced, but a caveat so that readers don’t start using raw materials (Essential oils especially) and cause a therapeutic misadventure.

    Dog’s skin pH 7.0- 7.5 (can tolerate pH 6.5-7.5)
    so my suggestion is, make it as mild as baby shampoo & as minimal as @Perry suggested.
    Off topic, almost all dog’s skin conditions are either fungal infection or an allergic condition, so using antibacterial shampoo is going to worsen the skin condition of your dogs.
    I also suggest to stay away from SA and plant extracts.

    Add Tea Tree Oil, it seems to be the cure all!

    tea tree is a complete NO NO when nearing animals. especially cats and dogs, . I had a diffuser with some tea tree in it. couple of hours later both my pets had a tough time breathing and sat low on the ground, after visit to the vet we realised that it was the tea tree, with some extensive research did find out its TRUE, essesntial oils r a  complete NO. its very dangerous to the animals

    1 I see Stepan APB has Ammonium lauryl sulfate in in, wouldn’t it be a bit irritating? Why not just ALES? (and maybe add some ammonium xylene sulfonate)

    2 Maybe CAPB can be increased a bit more to make the formulation milder?
    (but too much CAPB makes it feel, I don’t know how to describe it, sticky when applying it but rinses off afterwards.

    3 Why propylene glycol?

    4 Why Polysorbate 20?

    5 I wonder if PEG-7 GC will make it a bit sticky, thus making dirt adhere more to hair?

    6 How frequent is Caprylhydroxamic Acid allergy?

    7 What about adding some bisabolol?

    8 According to Futurama’ Prof. Farnsworth, makeup for dogs is where the money is
    https://www.youtube.com/watch?v=gl3N5bbWn98

    Prof. Farnsworth: But once we free society from dependence on Mom’s dark matter, scientists will finally care enough to develop cleaner, alternative fuels.
    Fry: Scientists like you!
    Prof. Farnsworth: No, not me. I’m too busy developing makeup for dogs. That’s where the money is.
    Prof. Farnsworth: Good news, everyone!
    Amy: You perfected dog mascara?
    Prof. Farnsworth: Far from it. If you ask me, they look like a bunch of hookers!

    Ditto on the commentary about making it like a baby shampoo with a pH in the range 7.0 to 7.5.  Dog’s skin is much thinner and much more sensitive than human skin … a final pH of 3.5? … Belassi, your dog should bite you if you put this concoction on him! … back to the drawing board on this one.

    What you really need is a simple, gentle Glucoside-based shampoo with Ketoconazole (0.5% to 1.0%) and Benzethonium Chloride (0.5%) incorporated.  You could also try Miconazole as the anti-fungal.

    Climbazole is also used. It was (anecdotally) more effective for my dog than ketoconazole or miconazole. It is easier to work with, but also harder to get. There is a shortage and I had to get my samples sent from Germany.

    Chemfox, I am formulating pet products and I have read extensively that Tea Tree Oil is used for quite a lot of products, eg would healing for Herpes and especially if the would has split, in shampoo/conditioner and also for fleas/ticks etc. In Australia we have a lice treatment that basically uses only Tea Tree Oil and Eucalyptus!
    Maybe the Tea Tree Oil in the air and into their lungs for long periods of time becomes an irritant, but I have quite a lot of papers saying that it is strong component in pet products. I am not saying this just because I am Australian as I do not like the smell.
