Animal Cruelty?

Nothing like walking home and seeing two dogs outside in the heat with no water panting like crazy. I found a shepherd mix and a pit mix locked where we put our garbage. The shepherd was panting and looked thin so as soon as I got upstairs and I called ASPCA to have them investigate. I've never seen these dogs before and no one was around them. Hopefully, this was just a fluke and they actually have loving and caring homes or will soon have them.
