I guess, I'm a little confused, are you confining him to the kitchen for potty training purposes? and is he actually jumping on the counters, or counter surfing, also it's notrmal for them to stand with their paws on the gate, if you are in another room. I would give him a kong, or some of his other toys, to distract him from this behavior, to let him know he's ok, and you will be right back. Mariya would cry, and bellow if I left the room for a minute, and she was not confined, she has been the only puppy that did this, she grew out of it once she realized that when I left I always came back. Your puppy is still so little, it takes time, and patience but he will get there.You might want to try a clicker for the counter surfing, what you do is when you see him up there, tell him to get off, get down, what ever works for you,once he gets down from the counter, then tell him to sit, when his tush hits the floor click the clicker, and reward. Be consistant with him always.
