I just want to ask everyone to please make sure there is some way to identify your dogs. Monday I found a little Shih Tzu in a big intersection, and didn't know how to get her home. She's 14, almost blind, and deaf. Somehow she got out of her fence, and into the 6 lane highway. Fortunately, everyone in that intersection must have been a dog lover, as they waited while she wandered in circles, until I could get to her. Took her right to my Vet, and she had no chip, so no way to know where she came from. I had knocked on doors (I didn't think she could have gotten far) but no-one was home. I did tell one person I found walking, and a couple leaving a nearby cul de sac, where I was going. Still, I wasn't able to get her home that night. She did get home the next day, but I am sure it was very stressful for all concerned.
My point is that they never imagined she would get out. She doesn't even know how to walk on a leash very well.
Please. please, please, make sure there is a way to ID your pets. A chip is perfect, but even a fabric collar with a magic markered address, phone number and her name would have had Annie home that night. Even if they NEVER go out alone, accidents, fire and careless service providers do happen.
