If you'd like a list of what I use personally, please e-mail me. Otherwise what I would advise is that you use a shampoo that is SOAP FREE and has very little (if any) dyes or perfumes. Regardless of whether you are or are not showing this dog.
Also, with regards to treats, I'd recommend that you use things like baby carrots for treats; frozen peas; Solid Gold treat products (no frivolous uneccessary ingredients); Merrick treat products (not the food though-imo).
Like I said, if you want to know more about what I use on my dogs, simply e-mail me.
I hope this gets you started.
