b) call the local animal shelter
If you find a lost dog, the most responsible action is to call the local animal shelter. This ensures that the dog has the best chance of being reunited with its owner. Taking it to a friend’s house might not lead to the dog being returned to its rightful owner, and tying it up in the park or leaving it at a convenience store could put the dog at risk or make it difficult for the owner to find it. The animal shelter is equipped to handle lost animals and can take appropriate steps to locate the owner.
