Very striking looking dog! I've met one other Dutchie before (reject from a police dept. for sound sensitivity) and he was just an all around neat dog. Is the Mal in the background also yours?
They're definitely a tough breed, but she's the most loyal and intelligent dog I have ever owned. You have to dedicate a lot of time to this breed because they are very active and they love to work and play, but it's been very rewarding.
Do you do "personal" protection or schutzhund? I know they are very different. I am going to be starting personal protection with Caiza in the next few months. The trainer I found is wonderful and has been doing protection and SR for over 20 years. I am very excited about it!
