My parents live out in the country and people just drop of their dogs all the time. Thankfully my dad is pretty good about helping out the dogs that get dropped off in our yard, if they don't work out on the ranch then they get to stay in a nice kennel when we aren't around to supervise them, then they get rehomed. It's always so sad, especially when you run into a dog that won't let you help it because it's still waiting for it's owner to return. When we found my dog Pepper it was a few days before we could get her to leave the ditch she was hiding in. She didn't trust us at all and she was waiting for her owner to come and pick her up.
