Welcome to this forum! A few of us are trying our best to get this forum going and are SO pleased to have another member who wants to do the same. I saw your posting on the US forum and was just going to pm you, asking you to post it in the European forum. Then I saw this post. Kezza and I thought it a good idea to tell UK and other European members, posting on the US site, to post on this forum as well, especially when welcoming new members on the US site who are European. As you found, so many people just don't realize this forum exists.
As far as foods for your Yorkie, I cannot advise you as I am changing over to raw food prey diet (with lots of help, advice and hand-holding from other members!). I am sure that if you post that topic on this forum, you will get lots of replies.
Nice to have you with us.
Luv
