You can also ask if anyone has reported the dog lost. Most shelters will also keep a picture of the dog and your contact info in the event you take her home, in case the owners turn up looking for their pet. Don’t assume that just because you found the dog wandering the streets that she was abandoned or unwanted. It’s very easy for the most beloved of pets to escape home and go astray. You know you’d want whoever found your dog to make every effort to find you, so return the favor, even if it feels like love at first sight or fate that you found this new friend.
