Each Tuesday we will share a photo we received claiming to be the World's Largest Dog. A lot of you might have seen these photos. We couldn't verify the source so we leave it up to you to believe it or not. Photoshop can make look anything big. Let us know what you think. Have you seen any of these dogs in person? Do you have a photo that you want to share with us?

4) The Largest Irish Wolfhound:
This week's featured largest dog is an Irish Wolfhound again - just like last week. Again, I have a feeling that this photo is real and the photographer picked a very good angle, which makes the dogs look larger. The dogs are in front of the camera while the little old lady sits on the couch in the background as a comparison.
