When our puppies do their business outside or if they have an accident inside the house where they do a #2 and/or they pass gas. The odor is outrageous, is there something that we can give them to somewhat minimize the odor.
check what food you are giving them, that could be the reason for the smell. Ask your vet for advice on what food, Buddy had the same problem, and we put him and Codi on a rice based food, and it became so much better. You hardly smell anything.
Iky's got you headed in the right direction. There are several threads here about nutrition that should help you out, and a good link to start on is www.greatdanelady.com .
You've heard the expression, "garbage in; garbage out!"
