I took my dogs for a walk last night and when I was almost back to the house there was this man and woman walking and they had this little puppy running around them. It didn't have a leash or a collar on it and when it stopped to sniff my two dogs, they didn't seem to care if it was still with them or even concerned when they were pretty far away, so I'm assuming it wasn't their puppy. The puppy ended up following me around the block back to my house and I currently have it in my backyard because I was afraid it would go out into the road and get hit. I posted an ad on Craigslist to see if anyone was looking for it. I also just drove around the neighborhood to see if any signs have been posted, but there's nothing. Any ideas on what I should try next?
