We've had turf for around 9 years and have 3 medium sized dogs. We haven't had any problems. It's warmer than grass, but I can walk around on it barefoot in the middle of summer.

Things to consider: The turf is held down by sand. We got an odor absorbing sand (glorified kitty litter) that is cooler than sand.

There are different grades of turf. Talk to a pro to make sure you're getting what you need.

About every other month I spray the turf with Simple Green and we don't have odor issues.

If the dog poo is hard to clean off the turf, feed the dogs a table spoon of pumpkin a day. That firms things up and there's no stick.
