Heres the whole story, with pics explanations and then the video, you decide excess force or not? I say yes, the dog is nervous but shows no aggression around police, the officer went right in front of a dog in that situation and went to grab its leash, the dogs reaction was only normal being surrounded and now threatened. Officers do need to protect themselves in these situations, there are other means now like tasers that can stop an animal or you can even zap it again.
