This is one of two shampoos recommended on the French Bulldog Rescue website to combat the fungal and bacterial skin infections that plague many Frenchies. The other is Zymox. I ordered both. So far, I prefer this Micro Tek over the Zymox because my Frenchie's coat gets a bit oily within a couple days after a Zymox shampoo and does not with the Micro Tek. Micro Tek has a stronger scent which I find pleasant, does not bother my dog, and helps him not smell "doggie" longer than Zymox. I do note that the active ingredient in Micro Tek is triclocarban. This is a form of the stuff in antibacterial hand soap, which now they tell us is harmful if overused. So I am alternating the two shampoos for weekly baths so as not to overdo this chemical. So far we have been about 4 months fungal and bacterial infection free, even with the soggy ground during a wet winter.
