So this vaguely familiar lab mix comes to our door today, whining and upset. No collar, but clean and well fed. Walks right into our house, giving little whines, a passing lick to my face as it looks me in the eye. Turns and searches our whole house quickly. DS puts a leash on her and walks the neighborhood to find her home. The dog lives a few doors down. Her companion Labrador dog died from old age a while back, and according to the owner, get out all the time now (scraped her ear up getting under the fence gate) and is looking everywhere for her missing mate.
