Yes, we've kept every single post (not deleted posts or threads) since YorkieTalk was started in our archives and we plan on keeping it that way. There are some great threads and important information in there, and members can often find what they are looking for instantly by searching the forums. It is a great resource to have handy.
But if you can't find what you are looking for, feel free to post a new thread about it. Here is the direct link to the advanced search option:
