You should get the information about the owner call him or her to let them know that you have found their dog and that it is safe. If possible you might want to take the dog personally to address given on the id tag.

Get supplies from stores
After finding a dog, you need to quickly visit a store for supplies. In case you found a puppy, you need to buy a lot of dog food as they have a huge appetite. In addition to food items, you need to buy bed, a fuzzy blanket and cardboard box. You should also get a chew toy as puppies love to chew anything they get. In case you find an adult dog, you only need to buy food items as they are easy to take care of.
Settle the dog
You are required to find a comfortable place where the lost dog can stay and rest until you have found its owner. A couch can be a great option for this purpose.
