Hope he doesn't spot a cat!

Someone brought this pic into work and I had to share.

Out taking the dog for a walk, and met this great lady, and just hopping Rufus, doesn't spot any cats....

I know Mastiffs are big, but I'm thinking there might be a little photochopping goin on in that pic.

I also got that picture in email. Was going to post it but thought - the forum researchers will do their thing. So I looked it up because it was supposed to be the world's largest dog, according to the "Guiness Book". So, I found the picture with this caption:
UPDATE Apr 14, 2007 - Hercules Hoax
This phantasmagoric photo of "Hercules" has been recently circulated around the internet; however it is a digital fraud. We'll have a picture of the real Hercules for you on Monday. Check our latest news page.

But I do have a pic of a pretty large one:

Just saw that the Official "World's Largest Dog" was a Mastiff named Zorba that in 1989 weight 343 lbs and was over 8 foot long from nose to tail.

Hide the dog biscuits.

...Hide the dog biscuits.

WHERE!!!! You would need a safe, and a large one at that. A dog biscuit to him would be like us eating M&M's

Feeding him would be one thing, but cleaning up after him--woah!

Either way in regard to either dog; if he gets hold of your leg, it's probably a good idea to just let him finish.
