If the dog is safely approachable and friendly and you feel you can take her with you, entice her to come to your car with friendly commands or the promise of a treat. At this point, you can decide whether to take her to the local animal shelter or home with you. If you decide to take her home, we still recommend swinging by the shelter first. If the dog is collarless or tagless, the shelter can scan her for an embedded microchip with the owners’ contact info.
