Yes you can use that grass in the compost pile. The best practice however is to mulch mow the clippings back into the lawn. If you do collect your clippings, go ahead and compost it. The small amount of dog feces therein would be negligible and have no affect on your compost.

Whew....I thought you were asking about composting your pets.

lol, sometimes i'd like to compost my pets...
and yeah, if you are adding grass clippings to the pile you are probably trying to get a hot pile goin' right? if that's the case than it's definitely fine, you insurance lies in the heat killing pathogens.

but i wish that someone could help me w/ the human urine in compost dilemma, i used to use it but now i kinda don't, there was a huge discussion on it a while ago, and someone reminded everyone that there is a lot of salt in human urine and that makes for a good reason not to use pee in a compost pile....there are so many mixed opinions aobut it.
