For a quieter, less dramatic solution I suggest a pan of Golden Malrin / rootbeer cocktail. A few good slurps and it’s tits up in less than 3 steps.
Haha, that stuff works too fast. I am very selective on what and how often it might be used. I would never use it on a naybors dog. I would heap the poop up on the naybors doorstep for awhile. Then tag him with a bb gun or pellet gun. Only as a last resort to poison or shoot.
