Should I use the catch phrase that everyone loves sooo MUCH..."You cant fix stupid" !
That meaning, have a measured response to the action that may be irritating you! .....with that being said, kicking a 3-4 pound Chihuahua 3 feet in the air and 2 yards down the road because its nipping at your heels seems a tad excessive and YES, Id say Cruel! So carry on all you "Rambo" types..... its one thing to be defensive in nature when dealing with an unruly dog/dog owner and a completely different story to turn offensive on a small defenseless pet.....try that kicking trick on a 120 pound Pit.
