Erin was at my house and we were supposed to go for a walk, so we walked up and down the street asking anyone who was home if they recognized a digital picture of the dogs. I called the animal shelter to see if there was a lost report filed but I forgot to check the sex of the dogs. I ended up taking the dogs to a vet's office to get scanned for a microchip.
One of the dogs had a microchip but the other didn't. They seemed like friends and it turns out that they have the same owner. The microchip company didn't have contact info, but the animal shelter did (they had done the chipping). The first number didn't work, but I called another which turned out to be the owner's girlfriend. He came to get his dogs a couple hours after I found them.
Had the one dog not been chipped, I would not have been able to identify the owner and I would have had to turn the dogs over to the shelter. Hopefully the owner would have filed a report and been notified when I turned in the dogs. Otherwise the dogs would have been adopted into another home or put down. It's definitely worth every penny to microchip your pets.
