As photographer, my honest feeling is that this is nothing to just photograph. Forcing a dog to stand on its hind legs in order to take a picture and upload to get "likes" online really is in poor taste. If this didn't happen, the world would be completely unaware of the fact that this sort of abuse was happening. The poor dogs trembling in the videos do not even have a chance to consider running from their owners. Even if it were to cross their minds, a gas chamber would be waiting for them.
There is one more thing I felt as a photographer. Pointing a camera and clicking doesn't make you a photographer. You are also given the opportunity to try to make the best decision on how to convey the subject and record the moment.
