Hi there... Unfortunately this is a problem that you have created and its one that only you can fix. I think your pup thinks he's the more dominant in your home. Which is why when you take him out of the bed, all he has to do is bark...and he's right back in the bed?!? I dont think you need a muzzle, rather a stern "NO" when he acts out and sticking to your guns when he's barking/whining to get his way. It might be a headache for a few nights, but I think it'll eventually stop the problem...IMO.
Lets bump this thread up...so that you can get a little more advise
