Tiny Stray Poodle

The poodle is living in the garage, and I've been feeding him, and gave him a bath. He's blossomed with happiness in the care he's getting. He looks really rough though, even after a bath. My plan is to take him to the vet tomorrow for a check-up. Chances are he's not got a chip, because he's never been neutered. Another throw-away dog?

The thing is that I don't think I'll be able to easily give him away. He's too degraded by living rough for a very long time. I really don't want to keep him, either. My two dogs are enough, and we have worked out a happy accommodation with just the three of us. I'm not sure a tiny male dog will fit the dynamics.
