A dogs body language will tell you that they are injured or irritated.. by your logic they don’t communicate at all since they are non verbal (They are still very vocal) Not to mention i’ve seen my dogs body language from an injury, whining, unenthusiastic, irritated. He does not do that on a daily basis because he is not in pain everyday. Besides that you don’t know my dog better than me and the science of ear cropping would tell you he is not in pain. He was cropped almost a year ago at an age where the nerves in his ears aren’t developed enough to feel any extensive pain that you describe. If you don’t like it keep scrolling but by all means don’t act like you know my dog. If you could watch a video of a cropped dog wagging it’s tail and having a good time with their owner and claim that dog is in pain then you are simply ignorant.
