Wow, fun question! I would trust my good old lab with pellet guns, she’s great, rarely barks or gets upset at anything. Except an occasional cat that slips into the backyard. Now my Teddy bear, he gets a Nerf gun, terrible temper tantrums. The other day I tried to swat him off the bed so I could change bedding, and he kept howling like I was trying to rip his tail off or something.
