They sure don't look like they're starving to death! If you know who owns them, I would be talking to the owners about keeping them on their property. If they are not wild and will come to you, after talking with the owner and they don't take care of the situation, I would see if I could get a leash on them and take them to the pound. I hate shooting a dog, but have killed a couple wild ones that were running deer on a Texas lease.
