Bianca and Buddy like to go for walks in the farmer's field and play on/around the hay bales.
Ha! You can't get me!
Hi-yaaaa! I chase you!
Notice the foal blanket on Bianca. A Dane is a big dog.

Yeah, that's me looking like a doofus in the red hat. It's about a half mile walk to the field, then another quarter or so uphill to go somewhere isolated enough I'm comfortable letting them run. (Bianca believes a strong offense is the best defense, where strange people/dogs/sounds/sights/smells/etc are concerned)
