Removing Dog Urine from carpet??

Due to an illness, our dog had one single instance of urinating on our carpet. Because we saw it when it happened , we were able to clean it quickly with carpet cleaner. We knew of course that in spite of our efforts, it likely got into the padding, which we couldn't clean.
I have always heard you can never remove a urine smell from carpet. Is this true ?
Any home remedies that we might try at this time? This happened 24 hours ago, but tonight we detected the smell.
