Whatta face on that angel boy! Welcome!
Here's my best puppy training advice:
1) Remember, he's just a baby - he'll learn and you have to be a patient, calm leader! He's not eating the couch just to piss you off. He's a puppy! They try to eat couches! LOL
2) Did I mention patience? Also persistence. He's going to be --- and you have to be also. Toes are NOT for chewing. You can disagree with any unacceptable behavior without yelling at him - which will only serve to confuse him anyway at this point.
3) Enjoy your pup! He's going to be a GIANT couch eating monster in no time. Don't accept a behavior now because it's "cute" because it won't be when he's 65 lbs and doesn't know who his pack leader is!
I love his little "eye patch".....my Bo has that. Aren't they GRAND?!
