I'm sure the GSP will handle both birds and bunnies.You may have to adjust your hunting style some.I also express caution with bunnies, your dog may give chase and that leads to unsafe shots.I would however shoot any the dog happens to point and hold for a safe shot.Dogs associate what 'game' is by the animals shot for the dog,so if bunnies are in your hunt plans make sure you have a safe controled shot and if your hunting with buddies or freinds make sure they understand your rules.Take care,Jackson..
