I remember what a veterinarian told me one time: "All dogs which are alive and have teeth WILL bite under the right circumstances." Obviously, this guy didn't understand that.
“... will bite under the right circumstances”.
I’ve known some K9 officers through the years. The handler in this case is 100% to blame. First, K9 dogs aren’t “normal” dogs. They are trained at a young age to bite. The schooling of the dogs is intense from my understanding.. dogs that don’t show aggression when needed are washed out of the program. Secondly, the dogs get into a state of mind. When the cop “hugged” the dog to show a good job.. WRONG. I’ve been told to get them out of that type of state of mind.. the handler will remove them from all other people and reward them with a ball. The ball is used to bring the dog’s agitated state back to “normal”. The handler disregarded all of his training for a selfie.. the dog’s reaction probably isn’t surprising at all to professional, experienced K9 handlers. IMHO.
That was a great vet. Most are not that saavy.
This is ridiculous as you can substitute anything alive from an elephant to a Venus Flytrap with the word "dog" in this sentence.
