Decades have been dedicated to researching and developing what we believe is a premium and superior canine semen extender.

Canīnus-Ext™ protects the sperm cells during chilled storage & safe throughout your shipping process. It also protects the sperm from damage caused by temperature changes during shipping, also acting as a preventative from & oxidative stress while neutralizing any negative effects on the semen when being shipped. Just as the ancestry of our canines formed the ones we love today, we vow to carry your pets legacy on for time to come.

We are constantly pushing the gold standard for the processing and preservation of bull semen by providing the highest quality extenders. We work with a number of veterinarians and research engineers to improve our current products and to develop new ones.

Hoëk Labs prides itself on diversity. Our products are tested to ensure the success of shipping your prized stallions semen. Equine breeding facilities around the world put their trust in our reproduction products to ensure success. Our ready to use formula makes it easy for your shipping process.
