Good advice in this FB post about what to do if you lose your dog or come across a lost dog. And omg! the ending! You have a heart of stone if that ending doesn’t make you shed a tear!
And to add to this-probably pointlessly given the number of photos we all post-take pics from every angle and write a very full description in advance so you can post a description on DogsLost etc very quickly.
