Can pigs be washed with dog shampoo?

i have proper guinea pig shampoo called 'gorgeous guineas) you can get conditioner as well

wash hair twice with shampoo.

Of course, the above answer has nothing to do with what the question is actually asking. It is asking if dog shampoo can be used on pigs (as in swine, not the domesticated rodent). It is possible for you to use dog shampoo on swine, but for best results, I would use shampoo specifically designed for our swine brethren. It helps clear their skin of dandruff and flakes, and for added shine use Sullivan Brand "Sudden Impact" spray. Actually, any "Sullivan Supply" product is good at grooming swine.
