OK, with an English Bulldog (What else would "Mack" have?) and a Boxer, I'm also used to big dogs, but I would caption this pic:
" Yeah, look at these hooks (nice claws) and I'm not afraid to use them!!!"
I had a 145 lb. Lab at one time, and he had a tea cup Yorkie come out in the street and stand up on his leg (he didn't make his knee!) and bark at him. My Lab sat down, looked down at the Yorkie, then up at me as much to say "He's got to be kidding!!" then the next look was "OK, am I allowed to 'fetch 'em up'"
