^^^^ Nmbr1Ballr - congrats on puppy !!
a) Basic commands come easier once the fun loving bond is established.
I do this by daily playing, sitting on the living room floor...first I want the pup to respond to my voice and keep eye focus on me.
I avoid treats for training, so I will gently guide a pup into a sit with my hand & use a hand signal for stay...tap the floor with my hand to get puppy down.
- with loads of love and praise
b) If you don't want pup up on the couch, shouldn't let it be there, in the first place / mine sure loves furniture, and is respectful of its own leather love seat.
- my pup earned privileges when its good / learn to listen to me, it can even go out the side door ahead of me & I feel they sense the cause & effect relationship
c) I use the word "ITCH" to discourage puppy destructive chewing...in a stern voice / love and praise immediately following compliance.
d) A few days to a few weeks, pup should know basic commands...other than a solid recall.
After I train inside the house, than I redo exercises outside where there are many more distractions and I can proof our lessons.
