ground cover

I am a renter and while my landlord doesn't mind the dog I still want to be sure to take care of the yard.
I have a small cockapoo and a small area for him. What can I get that I can #1 clean regularly
#2 remove when (if) I move and the grass can grow back #3 keep down the pee smell!

New Mommie!

Male dogs (you mentioned his gender in your other post) do not tend to leave burn marks on grass like females do. Is it a sunny area, or a shady one? Damp, or dry? Different ground covers grow in different condition, so I figured I'd ask before I recommend anything!
