Seeing your dog cock his or her head to the side, in particular any time you are talking to the animal, is just too adorable. A few dogs do this and some do not, however those that make this gesture are doing so for very good reasons.
In most cases, a dog will tilt his head to the side in in an attempt to hear more clearly. Whenever they turn and tilt their heads the ear becomes more exposed in an up-and-more-forward position. The result is that the inaudible sounds that they were catching will become clearer to the ear.
Numerous dogs have learned to cock their heads to the side just because they get a reward. What is the reward? Your instant response is to say something such as, “Awwwww, like at Buddy with his head turned to the side, how cute!”, pursued by plenty of petting and soothing tones.
Whatever the reason is watching a dog (especially a Pug) tilting his ot her head is so funny. Here are three Pugs, Mabel, Minnie and Max demonstrating the “Pug Head Tilt.”
