What are you saying?: How to understand your dog's body language

Wow, it's not that simple. You probably don't have enough experience to understand the dog's language. Everyone knows that a dog goes to die when he leaves the family. But how do you know it wants something if it starts howling, barking, thrashing about? I can't even control it. I got this collar for my dog https://mydogtrainingcollar.com/best-wifi-shock-collar-for-dog/ and the training seems to be going well. Other than that, he's a naughty bastard. Without a leash, he doesn't obey. Not much time has passed yet though. The main thing is not to lose the taser remote so the dog knows where he belongs and that he is always being watched.
