Happy Birthday D litter!
4 years young ❤️

Cobra has officially been added to the stud list of the Police of the Czech Republic, and today we had our first official breeding. 🙂 🇨🇿🐾

Not bad for a dog that was bred in Canada and somehow made his way back to the country where so many great working dogs are produced. Life has a funny way of coming full circle.

Who knows… maybe one day a police dog bred in the Czech Republic will get exported somewhere in the world and people will look at the pedigree and see: “Canadian bred.” 🇨🇦

That would be a pretty funny twist in the story.

Either way, I am proud to see Cobra recognized and trusted within one of the most respected working-dog programs in the world. Onward. 🐕💪

Exciting news from the Czech Republic 🇨🇿

Olívie od Jemčinského zámku was bred to Xtris Cobra!

Olívie represents the strength, character, and quality of her kennel, and Cobra continues to prove himself as a powerful and balanced male. This pairing brings together two dogs with strong working ability, solid temperaments, and promising pedigrees.

We are looking forward to what this combination will produce.

Interested buyers should contact Václav Ouška directly for more information.

XTRIS Cobra IGP3, IFH1, V, Kkl lbz x Visa von der Sinburg IGP3, V, Kkl 2025/26

Cobra has always been different—not just in drive or structure, but in presence. He has “it.” That unexplainable quality that makes you stop and take notice.
Cobra is known for producing exceptional offspring who excel across various disciplines—from competitive sports and SAR (Search and Rescue) to nose work and obedience. His progeny consistently demonstrates outstanding drive, intelligence, and versatility. He also possesses a perfect on/off switch, making him not only a powerful working dog but also a reliable and focused companion.
