Argon has currently nabbed a crow, a mockinbird, a sparrow, a snake, a possum, a rabbit, and a squirrel. Not bad for a dog who is either fenced in a small area or on leash at all times. You would be horrified if you saw him get a bird while on a 6 foot leash.
Gambit brought me a mouse one time. Since I failed to check is mouth after last call (the last time I failed in that respect), he left it on my pillow after I fell alseep. Charming.
