Hi - OK two year old TAG - over the past 6-9 months - Bellissimo has developed a very annoying habit of a scream when he wants something. It is extremely piercing. Unfortunately we have spoiled him a bit and when he doesn't like his food, wants something we are eating or is left alone, he does the scream. I have attempted to replace the scream with a woo-hoo whistle. He does this very well but he mixes in the woo-hoos with the screams. Sometimes he will start with the woo-hoo and then go to the scream. I have attempted to bring him into his roost cage when he does the scream and has figured out he should woo-hoo on the way to the cage!!! I always say good boy when he woo-hoos and ignore the scream but our patience is wearing very thin. Any advice on this would be greatly appreciated!!
