Hi! Well done for making a start at sorting the problem - and it sounds as though you're doing exactly the right things! Yes, it's likely he will get worse before he gets better; it's called an 'extinction burst' - if something that's always worked before (dog whines, dog gets titbit) suddenly stops working (dog whines, owner ignores) the dog's going to whine louder and more to get the desired response. When this happens
do not weaken, or the dog's been proved right - he needs to make even more noise to get titbits now! ;)
So carry on putting him in another room when you're eating, give hime his food only from his bowl, and let him go on hunger strike if he wants. No healthy dog has ever starved itself to death when there's food available! :D :D
