[quote1331778811=Tonedog] Yeah in a fair chase in the open a big heavy dog won't catch a rabbit, they're not gonna be consistently running down rabbits, but circumstances can lead to it happening once in a while. Mind you, rabbits are nothing compared to jack rabbits and hares. You don't need a SUPER fast dog to catch them with some consistency. [/quote1331778811] Sure, in the end it's all just a statistics game (with every prey and predator really). Even if the rabbit has a 99% probability of getting away, for 1 in 100 chases this still translates into lunch. BTW, this was a Montana Jack Rabbit.
