What are you training it to do?

'Good' behaviour? Or some tricks/performances?

There's similarities, but differences also.

Generally; remember that the dog will never understand what you say, but will have an idea as to your intonation/how you feel when you speak to it. It may even pick up if you're feeling stressed by something unrelated to it.

Treat it as a family member, that's how it sees you. Be careful with play, some biting is natural when young as they have no hands so can laern to use their mouth similarly as you do your hands, so if young, let them try things, but teach them to stop if it gets too frequent.

Don't shout, it's like barking to them & they may interpret as support for their behaviour. Whispering close to them can be surprisingly calming!
