Years ago, we were "chosen" by this malnourished scraggly looking little dog. He had been dumped somewhere along the long road where our house was. We trapped him in a live trap thing. I took him to the vet the next day, they told me he was days away from death due to no food.He had one of those chips in him, but was unable to locate the owner, or so the person who answered the phone says.
So we kept him, he lived with us for several years until he passed away. We named him Little man, because he looked like a little old man with a scraggly beard.
