Where should I start?

[Buzzooka Joe]

I got a 7 week old puppy Monday, he is now pretty comfortable with my home so this weekend I would like to start doing some training with him.

What should I start with?

He knows what "Nay" (No) means now an I'm pretty sure he is atleast slightly aware of his name "Hugo" and what "here" means.

the best things you can do create an unbreakable bond and trust .
Get a feel for the dog , and connect with the dog so that it gets to feel and read you . That comes from being , not from training. Quality time. Don't go so fast . In one week the dog is just getting his bearings , adjusting to not being with mum dog, littermates, change in schedule, food, water, caretaker, growing . The pup needs uninterrupted private time for sleep , for his physical growth and immune health , stress taxing both . He needs rest period to let his experience sink in after you think you have taught him something.
Teach the dog that he can trust you, that you are an honest broker , that you are consistent and fair .

Puppy class! I got my puppy into our first puppy class when he was 9 weeks. You and your dog will both learn so much.

Instead of putting him in situations where you always have to go "nay" to the point that it is the first word he understands, manage his environment and supervise him and set him up so he does what you want but he thinks he did it all on his own. Then you can replace the 'nay' with "Good Puppy!", because they always need about 10 positives for every negative.

At this age, you can start using food to lure them into a sit or down, if you want to train stuff, but the most important things to work on is building his self-confidence and focusing on you. Make everything fun and make everything a game for him. Associate his name with positive interaction and food rewards, so you can incorporate that into his training and handling.

But mostly, just enjoy him and let him enjoy you!

Much better to set him up to succeed and do well to earn a reward, then have him fail and go around the house with the no no no no .

PUPPY CLASSES! Ideal way to teach in an appropriate manner and logical progression.

Your puppy learning to PLAY and engage with you is the MOST important 'training' you can do. This is a skill for BOTH of you that is important for the rest of your dogs life. click this --> Engagement - Key to Training

I wouldn't go too hard on training right now, as others have said use these first weeks with him to bond and to gain his trust. He is still a baby and trying to soak too much in at once could be overwhelming. Congratulations on the new puppy.

I would work on socializing him with family and friends. Puppies that young really need their shot first before you start bringing them to places where other dogs are.

Work on teaching the puppy him name. Work on the recall just introduce him to training but don't except too much. Make it fun and positive. Work on teaching him manners Let him know he can't bite people. If he bites say ow in a high voice and stop playing. He will soon get that when he bites the fun stops. Little things like that would be good.
