Start 'em , but don't push. Some dogs bloom later than others. Get some rabbit scent( cabela's sells it for breaking pointers) and lay a trail in the yard. Even before this, I'd hide little pieces of bacon in the yard to get him to see that "using my nose is cool!". Iv'e seen some run at 3-4 mos and others, still good dogs, that never really "got it" untill they were a year old and then one day...Click! They just turned on! Good luck!
