awe right catch .i would say its always the dog thats easily fast enough,but reads the hare and puts the strike in and times it right.the other dog might be slightly quicker ,but lacks the craft.so in time the SLIGHTLY slower dog would be the pot filler.in an ideal world the faster dog has brain and stamina, then he wins. so many permatations really
Supose it comes down to.Witch dog is better placed at the the right time.
