I lived with Mum and Buster previosly. From the day we got Buster, till he was 5 or 6. I always have used the same words, same tone of voice when it comes to both Fonzi and Buster so now, when I go to speak to Fonzi or hold him etc, Buster gets jealous, barks and scares Fonzi away. This is the only problem we have. What can I do about it? Buster is so used to me calling him 'baby' and 'darling' but I've always spoke to Fonzi the same way.
Any ideas to stop Buster getting so jealous?
