Though I really know nothing about it, it'd seem they could team up to properly euthanize the dogs for a similar price to bullets or gas driving out of town. Our regular dog pound will euthanize a dog for around $10 last I knew.
I guess it is
closer to being humane to shoot them than to leave them for dead on the outskirts of town.
If I couldn't pay my garbage bill & took my trash & dropped it off I'm sure someone would go into a tizzy. And I don't have a living, breathing mammal in the trash. Not to mention what the dog could catch disease wise then bring back into town, or attack someone out of desperation for food.
