I personally have never had much luck with the corkscrew type tie out stakes, both of mine (with little force) can uproot them.
But I have one just like the picture I am posting, and it works great for both of my dogs (who weight 85 and 120lbs). Neither of them have pulled it out of the ground, and both dogs are strong. Even more so since we began weight & sled pulling.
I think the reason this one is so much better, is because of the rotation it has where you clip the tie out line, and it doesn't stick up, so the stake can't be pulled sideways where the soil will loosen and "give", causing the stake to come out of the ground.
This kind is sold at Petsmart too, only it's in green.
