I love dog parks! As long as your Yorkie is fully vaccinated it should be fine. It is a great way to socialize for you and your dog. I just met up today with another YTalker today at a dog park and it was so much fun. I always just make sure that there is a small dog side and a separate side for big dogs. The big dog side can get a little rough for our little ones. Have fun at your new dog park should you decide to go.
