i enjoy the first one because of how tense the dog is and i feel this creates a better interaction between the girl and the dog, even though it is less obvious. i like the expactantness of the dog and the way the owner seems to be ignoring him/her. as a few other people have said, my problem is it is that it looks like the shot has been framed to include the dog more than the owner and she is cut off a bit - but this happens in both shots, and overall i like the first one more.
I have to go with the first one, mainly because of the tension between the dog("Please feed me, me iz a good pup!!!") and the owner eating the burguer like without noticing the dog's applicative stare. Great moment there! Definitely the first one.
P.d - Totally agree with =Eliza-mac's statement above.
