Sorry I really didn't know where to post this as Maisie is 16 weeks old today (puppy) and has started incessant barking (behaviour) because of food (feeding)

I swopped her over to raw food two weeks ago and she absolutely loves it, I mean reeaally loves it. So much so that as soon as I get near a work surface to prepare any food, even a cup of tea

she starts a high pitched bark that just won't stop. I know it's only excitement as she thinks she's getting some grub but I want to nip in the bud before it's a problem.....if it isn't already.
I've tried the folding arms and turning away until she is quiet, but that just turns into a Mexican stand off as she just barks even more frantically.
Apart from this she is a little darling. Has anybody got any advice about what I can try to stop this?
