My Ibizans always *naturally* returned what they caught to my hand.
I don't let them chase bunnies anymore but occasionally, they, the PPM or the Dobes will hand me a nice, fresh mouse.
Dobermans are excellent hunters.
My teen-years Dobe put my dad's obscenely expensive, highly trained Brittany Spaniel to shame.
His sire had a field championship...and yes, that means a ~hunting~ title.
My dogs bark with what I call their “rabbit bark” when they see a rabbit in the back yard. I open the door a crack and the noise gives the rabbits a ‘heads up’ before I actually let the dogs out.
Rabbits must be incredibly stupid to keep coming back day after day.
