Ugghh!!!! Just watched it again, and my VERY FIRST thought about this animal, which was shocking to see an animal appear in the video, was, and still is, that this is a pitbull puppy mixed with some other breed. I believe the little dog is probably about 4 months old, which is close to how long LM had been in that particular apartment.
GRAPHIC WARNING.....
I sadly believe the dog had been fed nothing but raw meat, and it had been denied food, i.e. starved, for a period of time leading up to the filming of this disgusting act. I do not believe a normal puppy would do what this one did. A starved and trained puppy would. After watching the video again, I do NOT believe LM was a cannibal. He definitely carved out a piece of flesh from the hip of this poor soul with a fork and a rather dull knife, but I do NOT believe HE consumed it. If you watch the shadows on the video at this point, he immediately moves behind him to get the puppy. I just want to add, that if LM wanted this video to be shocking, he succeeded, but at this point in time, after watching his miserable and horrible attempt for attention for a second time, I am more disgusted than shocked. Here is a picture that is the closest I can find of the animal in the video. There are several puppies in the link but I believe the animal in the video is closest to one of the black and white ones in the link.

"Montreal investigators say they also have evidence of cannibalism, "as gross and as graphic as it could be," Lafrenière said. "Yes, it was seen on the video."
