"Excuse me, what's so funny?" That's what we bet this golden retriever is thinking as its owners explode into laughter at its super mean--yet completely accidental--behavior towards another pup. Just watch.
Granted, these two are sitting a LITTLE too close for comfort, so it's not really the bigger dog's fault that its giant tail is about to cause some serious harm. When the dog (whose name seems to be Jayden) gets excited, that tail starts wagging-- and the poor tiny dog behind Jayden feels the effects almost immediately, getting whacked in the face again and again.
Unless, of course, feisty Jayden knows exactly what is happening to the other pooch, and keeps it up anyway. Payback for some early doggie transgression, perhaps?
