Thanks this helps me a lot because I don't want to make him stressed and also how do I train him from not barking at bikes and other things
That's why you need Puppy Kindergarten (as a starting place!
) If you don't have experience raising a puppy, you are going to need a LOT of advice.
We can help you from time to time when you run into a snag, but we can't teach you to train your puppy from start to finish. A very good book on raising a puppy is "The Focused Puppy" by Deborah Jones and Judy Keller. It's my favorite puppy training book: https://smile.amazon.com/Focused-Pup...+deborah+jones
But you will likely get suggestions from other people too. Read all you can before your puppy arrives! Also look up KikoPup on YouTube. She has very good videos on all sorts of training issues.
Your first training tasks will be potty training and training the puppy to settle and be alone comfortable for short periods. You can search the forum for LOTS of threads on these issues. Barking usually comes later... Tiny new puppies rarely bark a lot... It takes a few weeks to "find their voice". You do want to be careful not to even RESPOND to demand barking, or you can create a problem that is very difficult to solve.
Puppies are often "mouthy", but that's really not the same as "biting", which is a VERY serious behavior problem. If a puppy is being to rough with their mouth, first try saying "OUCH!!!!" in a loud, high-pitched voice, and turn away from the puppy this is what a littler mate would do, and with many puppies, that makes enough of an impression. Some are pretty relentless, and with those puppies, if they don't respond to the "OUCH!!!" immediately but gently, pick them up and deposit them in their ex-pen for a minute or two. They may resume the minute you let them out, and if so, pop them right back in the ex-pen. Don't say a word. If you are consistent and persistent, they will learn that nipping means that they can't play with you anymore, and that's no fun!
You just have to be more persistent than the puppy. (and remember not to laugh, no matter how funny they are, because that is very often encouraging!
Most important, remember that puppyhood is very sort in the scheme of things. The bad things will pass, and the good things will go by oh-so-quickly. Take LOTS of pictures and video!!!
