for now. keep it fun. most important is teach him the basics. come,heel and such. as he grows. show him where bunnies have sat. show him excitement he will catch on fast. I trialed draathars years back. every sporting dog wants to learn.. one thing you will be doing is shaving him down. bunnies love the rough stuff. please remember after runs check his feet /pads for burrs..
your gonna have a great decade of loyal fun.
