Oh yeah, and Welcome to YorkieTalk!!! To start a new thread, you can go to where it says "Forums" on the top of the page. Click on that, and then click on the category that best fits what you're wanting to start a thread about. For this, you would put it into the Health & Diet section probably. So you would click on that, and then click on the left hand side of the page where it says "New thread"
Hope this helps!!
