I'm not in your area at all - but I would suggestion checking your local shelters or rescue groups. Here in Iowa the Animal Rescue League and a no-kill shelter, Animal Lifeline of Iowa have special events that they list on their websites.
Sometimes they list events that are fundraisers for their organization & say whether pets are welcome. Other events include dog shows & pet expos that are going on in the area
The other going on around here in the next week or so are dog swims - the local pools start closing down with school starting they let the dogs come in & swim the last night
Also, I would suggest go to
www.meetup.com - maybe you'll find a group in your area - or put the word out that you are looking for others to meet - either yorkie or small dog owners
I'm excited because on Thursday I get to take my furbabies to work for a Dog Days of Summer event - they will only be there for a short time - but I'm excited.
