You can't go wrong with water & I try to limit anything extra. I'd just use water.
Has anyone ever used these type of products?
I saw that they're making one specifically for dogs now: http://manentailequine.com/products/spray-away-dog-wash/
I have used similar products (Ezall and EQsolutions) on my horses with positive results.
I'm wondering if this would be a better alternative to just hosing muddy dog legs off before they come in?
