Horsing Around

Two horses were walking back to the paddock after a days training. One says to the other "I can't understand why we are so slow, we come from good stock, we have the best of food, great trainers, and yet we come last in every race."
There was a dog running along side them who overheard and said "I know what your problem is. I have seen you race and it looks to me as if you race off at the start really fast and use up all your energy and then you have nothing left. What you should do is pace yourselves and when all the other horses are tuckered, put in a spurt and you're sure to win. What do you think of that?".
The horses looked at one another and said "WOW, a talking dog!"
