The ending is the best:
“To test this theory: Lock your wife and your dog in the garage for an hour. Then open it and see who’s happy to see you!”
A dog’s love is unconditional.
I always notice how all dogs do learn to follow our voice commands, to some degree of accuracy, but they never need translators, no matter the human language directed at them. It’s like they are pre-wired with a universal translator, LOL, or that somehow they “hear” past our human language, picking up on our intent emotionally through the myriad inflections in our voices.
Dogs understand Spanish!
