At ten weeks he is going to nip and bite. Teething, nervousness and just exploring with mouths are gonna mean it’s what pup will do. Be patient, praise desired behaviour, ignore unwanted behaviour. There is an article on here about bite inhibition training. You can also see what we went through recently with out pup, Zennor.
OH went through trauma with his nipping. Eventually it calmed down through us patiently working on the inhibition. The one day it just stopped...well until adult teeth started coming through
IMO don’t be in a rush with pup. Have fun a create the bond so you become pups world. Make sure he sleeps more than he already is...I don’t know how much sleep he is having but I know he will need more based on our experience with Zennor.
For me most important thing was to teach pup is recall. Sit and wait are the same thing for me so I do not differentiate between the two. What ever “training” you do just make it a game and have lots and lots of fun creating the unconditional bond that will reap rewards when training gets more serious later on.
There ain’t no rush with a pup, just let it happen naturally through play.
