DNA TESTING

How we use DNA testing

A genetic health screen provides extremely detailed information that we use to improve our dog’s health, optimize breeding pairs, improve litter outcomes, and contribute to longer lifespans in our breeding lines. DNA testing is one of the most useful tools we use in all of our breeding pairs to help identify potential deleterious genetic variants that might be passed on to offspring. Genetic results are used to properly pair dogs to avoid producing at-risk puppies. Knowing whether a dog is clear or a carrier of a deleterious variant or at-risk from the variant and how to use DNA test results helps us decide how to move forward with our breeding program.

Upcoming Breedings


Updated 5/8/24 - We are expecting the Ricky and Tinkerbell litter somewhere close to 6/6/24.  If all goes as expected, those baby bears will be ready to go home around 7/25/24.  Thereafter, we have several litters planned that will be ready to take home September through November 2024. ​ Please contact Denise (818 249-2154 -text or call) for more details. 

Contact us now to secure your spot on our waiting list. We rely on our waiting list to find the perfect home for all our precious English Labrador Retrievers. We have found that this process gives our forever families the best opportunity to get exactly what they want while also reducing the amount of time they need to wait.

Once the beautiful puppies are born, we will provide continual updates for the first 8 weeks of life. This includes pictures, videos, facetime/zoom calls, texts and phone calls. Puppy selection usually begins around 7 weeks old. This is when we begin to get a better sense of the puppy’s personality and how it corresponds to what you’re looking for. 7 weeks old is also the time we schedule in person visits so you can interact with the pups and find out which puppy you connect with.
