Well...
YOU WERE ALL WRONG! With the exception of Furby123, but his feelings were mixed..
The camera is a very professional camera, a sports camera, used by the photographers of Football teams such as Manchester United, Manchester City, etc..
The camera was set to speed-picture, which captures the moving object perfectly. The dog, is my grandma's, and that is the highest she has ever cleared that fence, although she does clear fences very well, because she's HUGE!
Here's a couple more pictures which are clearly not chopped, I just thought this one stood out a little, and I would test you all, but yeah, I was there, I took the pictures, I was walking the dog, it's completely legit!
