My 3 1/2 month old Shih always barks, jumps up & down when I start making his food. He is a very good eater...finishes the bowl in no time. I know he's still a puppy, but will he break off of this habit? When he does this, I repeatedly tell him "QUIET" and/or I pick him up, which kinda helps.
You need to convince the puppy that barking not only will not help him get his food faster -- it will slow things down. When the puppy starts barking, quit working and fold your arms. Ignore him. Appear to zone out and stare into space if you have to. Wait until he is quiet, then resume your work. If he starts jumping and barking again, stop again.
You might need some ear plugs, but eventually he'll catch on: Showing self-control speeds things up and "hurry up barking" slows things down.
I've got a 4 month old and I do this. Doing a "happy dance" when I'm getting food ready is fine. Barking and jumping on me is not -- and gets the stall treatment. I also have him sit/stay when I put the dish done on the floor. If he dives toward the dish before I say "OK", I pick the dish up and start over. He has learned very fast that self-control = Good things.
