I don't go to Medina Park. My Jessica prefers Bellevue Park
Plus, this is very friendly SMALL dog park (Medina is better for big dogs) One day 15 yorkies were there. It was not a special meeting, people just come at the same time
Anyway, a few yorkies go to that park all the time. One girl has 3 yorkies, and another with 3 yorkies comes from Seattle! I used to go to BPark every day, but now my Jessica doesn't like when too many dogs arounds and prefers my company. Snobby girl a little bit

She loves to play with one dog only - she doesn't like "kindergarden".
Anyway, I definitely recommend to visit that park. This is not an officially dog park, however we let our dogs run around and have fun. If your dog is intelligent, doesn't bark much and not agressive, you will be always welcome there. The only one time someone complained probably, because we saw a security who asked us to put dogs on the leashes...
But it was an exception....
