It's wrong to hurt your pet.
Dave's dog Sparky has had a bathroom accident on the carpet right in front of Dave.
Dave wants to show his dog that going to the bathroom indoors is bad.
Dave looks at Sparky to get his attention and says No sparky repeatedly so Sparky gets it.
Dave runs up to Sparky and kicks him in the ribs causing major pain to Sparky.
Sparky understands that he shouldn't go to the bathroom indoors and happily runs around again.
Sparky runs away no longer trusting Dave and thinking that Dave is an evil person.
