Well, I was going to meet his mom after work, but she couldn't wait that long and left work early to meet my boyfriend and pick him up. She was just so happy that someone found him and kept him safe. After I found him on my patio last night, I walked around the neighborhood with him, and then took him home and drove around looking for Lost Dog signs or someone looking on foot. After finding no one, we gave him food and water and a desperately needed bath.
I called Animal control this morning to see if anyone had called looking for a boxer. The lady at animal control said "absolutely, and she's frantic, please call her right away", and gave me her name and cell phone number. She was so, so happy to hear we had him. Seems she was out all night with a flashlight calling and whistling, but evidently we just missed each other. She asked what she could ever do to repay us, but I said nothing. I know how I would feel if my furbaby were lost and I just wanted to make sure he made it home safely. I love happy endings!
