Lisa, i agree with you! dog park can be filled with out of control dogs!
I found a GREAT place here in North Dallas. It's a GREAT day care

When Oxford will be ok from his TPLO, i will begin working with the guy over there.
i have borded Oxford there, and he had a blast!
Oxford is dog reactive - fear aggressive.
The man say they start the day with a pack walk, 30 min on leash, all boarded dogs together.
Then they are allowed to play.
Oxford played with every dog there!! No sign of aggression maybe because he trusts the owner of the daycare? Maybe Oxford feels that this man has control and nothing will happen to him?
Anyway, this man is very very nice and agreed for me to use his place to work with Oxy.
I will come maybe once a week first, then twice a week... not long first.
Then he will let me know when he sees Oxford completely relaxed around all dogs.
Then maybe, i will be able to enter the place.
Oxford tends to be way more reactive when i am with him...
over there, his "best friends" are a great dane, a doberman and a pitt

i have many pics from the guy so he could prove me my dog was NOT aggressive at all!

i am so happy i met this awesome man!
