Social media has revolutionized the way we find homes for pets and raise money for animal related charities. Last month, Facebook aided rescuers in locating a stray dog in distress  and, most recently, Twitter helped an adventurous pup find his way back to his family. 
Deirdre Anglin's dog, Patch, went missing last Tuesday in Kilcock, Ireland. She posted photos of the Jack Russell Terrier on Facebook, but didn't have much luck.
Patch wasn't discovered until he boarded an Irish Rail train to Dublin the next morning. At first rail workers thought he might be a passenger's dog, but when he remained unclaimed at the final stop, it was clear that the pup was lost.
Irish Rail took to Twitter with a “Lost dog!” photo, which was retweeted more than 500 times in a half an hour. Deirdre Anglin soon saw the message and tweeted back, “That's my dog!”
Patch and Deride were reunited and the terrier became an overnight celebrity. When Deirdre took Patch home on the train, fellow passengers kept asking if he was “the dog from Twitter.”
Twitter was able to reunite Deirdre and Patch quickly, but I have to say, I'm equally amazed how pet friendly the Irish Rail is. My local commuter train, Metro North, welcomes pets on leash, though I rarely see animals on board. However, if you need to travel longer distances, Amtrak does not allow pets.
On Irish Rail, small dogs are able to ride the train on a person's lap. Apparently canine passengers are so common that the rail workers didn't think it was that strange for Patch to be wandering about.
If only all trains were so pet friendly!
