The SF yorkie meets happen to be very near where I live, and whenever I took Thor to the park, people would ask me if I took him to the meets.
Apparently there was only one SF yorkie meet, but someone started selling "Yorkies for Obama" t-shirts at that one, and there was a brouhaha over the fact that there were no "Yorkies for McCain" shirts (no, I'm not making this up). This resulting schism caused someone to form a rival yorkie meet, so now there are two every month.
Try just googling "yorkie meet" and your city, it will probably be the first link. Or "small dog meet". You can also try
Do something, Learn something, Share something, Change something - Meetup.com and search for your city.
PS - I love dolphin training too! You must be into Karen Pryor. Have you read "Lads Before the Wind"?
