That's true, Chloé.

We put a lot of things away because of our crawling baby and the rest went away when the puppy came in.

No shoes etc.

I also take it as my own fault when he gets to something to chew.
At the beginning, when we got Max and he was still a puppy he chewed even his (expensive) brandnew dog bed. And when I thought there wasn't anything to chew he chewed a power cable of a floor lamp, luckily for him it was unplugged.
Nathalie, love your rambling! Is that a reason for you not to apologize and to carry on? LOL. My DH greets you - I told him that you wrote here that it's better to let the puppy not chew anything that's not his and he said he was so glad because he wasn't able to remember what Bodie is allowed to chew and what not. He said you're a smart girl!
Could you please add on some rambling about puppies and kids?

You mentioned that toy thing which we practice, he isn't allowed to play with kids' toys. Do you have any other tips?
Col has provided you with fantastic tips and along the jumping I want to add something: Jumping on kids, licking their faces, etc. Most people think it is cute but that too is a sign of disrespect and you should not allow him to do so. You have a crawling baby, right? Well, she of course can't say anything - you have to do that. The dog has to learn to give her space = respect her.Yes they can play and cuddle together, but you have to control it. If it gets too rough, you have to tell the dog off - and like Col said - calm and assertive! And when he does something good: praise!
When you go for a walk, don't let the dog walk in front of you, you are the pack leader, so you be in front. If you go for a walk with the pram, same thing, he has to walk next to the pram or slightly behind, the baby/kids are above him in the pack.
If the kids are running around, screaming, chasing, like kids do

don't let him join to get too excited. It could trigger prey or hearding drive - biting in ankles, pinning the kids on the ground, etc. Now I don't say that every dog will do so with any things I am saying. Some dogs are the best behaved dogs right from the start, never get into trouble and always seem to do the right thing. What I do think though is, that prevention is much better then trying to fix things afterwards.
Unfortunately, I've read and heard either things and info, that are too general or their authors are like "awww, poor little one, you don't let him chew the kids' toys? what did you expect when you got him? it's a tiny little puppy!" etc. etc.
I absolutely agree with Col here, those are the people that usually have some sort of uncontrollable dogs. Many of them probably tell they don't want to bark any commands or that they want the dogs to love them because they are so soft to them. If somebody is telling you that and they have kids, ask them: Do you kids have to obey rules, are they allowed to do everything? Don't you love them?
And of course you don't have to bark any commands

LOL
A word to the rewards: It doesn't need to be a food reward, think of praise good boy, the bridge word, a smile, a short pet, a play with his favourite toy or going to the dog park after a walk are all rewards. I even let our dog work for his food: I let him sit, drop, stand, stay, etc. As a reward he gets his food.
I am not perfect and I don't know it all but as Col I am passionate about it and read a lot of things, also trained to become a dog trainer.
