At Sisu Koira, the goal is to produce stable, healthy and correct dogs with true to breed workability.


The key is balance. A dog can be pretty, but timid and useless. Equally, a dog can be a skilled and courageous worker but not be conformationally correct.

There is no perfect dog.

But through selective breeding and being incredibly fussy about the dogs we choose to work with, we can get damn close.

Our strategy includes:

  1. Ensure correct structure by selecting dogs we feel best fits the standard, engaging other aficionados to help assess our dogs and competing in conformation events when possible with breed specialty judges. We will always measure our dogs against the standard, not what is en vogue or popular in the all breed ring.

  2. We will diligently health test our dogs, utilizing OFA and/or Pennhip assessments for hips, elbows, eyes and cardiac. We will follow breed recommended health testing requirements when they are released, and CHIC certify our dogs where possible. Our Dogo Argentino puppies will be BAER tested to ensure sound hearing.

  3. We will not compromise on temperament and drive, and assess this using structured temperament tests including but not limited to Aptitude Testing and Hunting Temperament Testing, when possible. 

  4. We will raise our puppies using Savvy Socialization methods by Avidog and implement specific and relevant components of the Puppy Culture program, and complete temperament testing around 52 days of age, to maximize best-fit placement and provide tips for success in their new homes

While we can do our best as breeders to produce stable, healthy and well-raised dogs, it is important to understand that our dogs will still require a lot more commitment to regular exercise, mental stimulation, firm boundaries and strict containment than your average family dog breed. 

Before inquiring about whether our working breeds are a fit for you:

  • Can you provide 5-10 hours per week of physical and mental stimulation for your dog?

  • Are you able to dedicate the time and structure early on and follow an individualized socialization plan for the first 2 years?

  • Can you provide an outlet suitable for moderate-high energy, prey driven or defensive dogs? 

  • Can you properly contain a dog who's drives will make it want to chase, catch and kill small animals including domestic animals like cats and small dogs?

  • Are you prepared to deal with same sex aggression and/or dog aggression in general? 

  • What type of professional support will you need to be successful (trainers, veterinarians, boarding services) and are they available to you? 

In order to maximize successful placements, our application process includes a comprehensive questionnaire and a live video or in-person interview.

We also require references.
