Cocoa (Labradoodle) and Jade (German shepherd) had a great time chasing, wrestling and generally having a great time with lots of freedom. They are both quite young dogs and of a similar size, I have had to put them back into their own units for a rest or they would still be playing out now.
I have closed the hatches down for a while to keep the heat in from the under floor system. The dogs in my care have all had 2 good play times so I think they are happy for the rest. It is all quiet anyway.
