How to find the owners of the dogs found in the street

If you find a dog on the street, this is what dogs and pets recommends that:
First, consider the safety of the dog and yourself. A frightened or injured, possibly dog may behave unpredictably. A sudden movement can frighten him, what would cause him to running out into the traffic, or even that you attack. If the dog looks or acts threatening in any way, or if for some reason you feel insecure about the situation, stay away from him or her and notify local authorities in control of animal or better, call a veterinarian.
If the dog seems accessible, remember to use caution and common sense. If you're lucky enough to get close enough to earn his trust, he still has the risk of being bitten. Even a small dog can inflict a painful wound, and if a dog whose vaccination status is unknown are advised to undergo preventive treatment for bite.
When you approach the dog, talk to calm and reassuring offering a mouthful of food.
Once you've succeeded in approaching and gaining the trust of the dog, the best care you can give is to try to return it to its owner.
Please always seek the owners before anything.
You can enter our pets Forum, publish the case, many active users disseminated it by all the social networks and that way will find the owner of the pet.
Parties are advised to a descriptive title, example: dog labrador found in Mar del Plata.
In this way, it will be easy for the owner to find this information.
Also recommended: posting in the section for "lost pet", "found pet"... with a good description "features specific, example: If this castrated, if you have some cicatriz…" and attach an image. It is also important to leave an email or phone contact. That would be all.
