No updates on Ace. No one in the neighborhood has seen him. I was out looking for him again today. I did have a discovery of sorts though. While I was out I found a tiny cold puppy taped up in a box. She had been tossed out of a car and left to die. I took her to the vet and she will be fine. I took her home with me. She has a couple of places of missing hair (not ringworm or mange, vet checked). My vet thinks she's 2-3 mos. old and a chiwawa mix or min pin mix or even a daushound mix. She weighs less than 2lbs. I hope to find Ace soon. The police told me that several dogs have come up missing in the last 3wks.

That didn't give me much hope of finding Ace. At this point I think he was taken.
Edited to say that all the dogs that were reported missing the last 3 wks are small breed and even small mix breed dogs.
