The German was from East German bloodlines. He was the most intelligent, most obedient dog I've ever owned.
The Belgian was one of the sweetest dogs I've ever owned. He had a strong drive to please, and was a little needy when it came to getting attention, but as gentle as the lambs he was bred to protect.
The Dutch Shepherd was an outright psychopath.
I remember Timber and Ranger, but don’t recall your mentioning the Dutch dog. What was his/her name?
