I have had great advice from this forum so hoping someone can help. First time puppy owner but second time dog (10 years) owner. The lab puppy is usually with me in the kitchen so we know what he is chewing/destroying. We do clicker training and he has loads of toys. And a crate. But now all of a sudden when I am preparing any food not only does he counter surf (I am used to that) but when i tell him 'Off' he then sits down and barks at me. Constantly. I know I should ignore, leave the room etc but with food around this is difficult. Should I give him a kong when I am preparing food? Or crate him (he will still bark) or put him in the garden? Perhaps we are entering the adolescent phase.
He's challenging your decision to keep him away from the food.
Our Lab did this. We put her Kong in her crate and shut the door, with "Bed! Good girl!". It took a while but she got the message that while we were preparing food she was not allowed to bother us. We ignored any barking or whining. Now she has a choice - it's either Bed or Out (outside or in the other rooms).
Absolutely no counter surfing allowed at any time.
When you tell him "Off" and he gets off the counter, does he get a reward? At such a young age (and a lab!) he probably should still be clicked and rewarded for this, otherwise why would he keep responding to the off command? I'd give him his reward and give him an alternative activity, either the kong as you say, or a sit-stay, or send him to a mat. This should distract him from making a noise, but if he does bark just ignore it.
We have a firm rule, 'good dogs' who lie quietly on their mat and don't bark, jump up or paw get fed a stream of treats. 'Bad dogs' who do these things get cheerfully sent straight outside or into the hallway. The pup still sometimes forgets herself and jumps up or paws at my legs but it's not rewarding and she's doing it less and less.
The dog I lost recently was a master at lying on her mat AT you very pointedly.
