Planned Colorado Mountain Dog litter
Due Jan. 2026
I'm Lindsey H., the breeder behind Tierhaus 23 located in Elbert, CO. Our goal is to produce pups of sound mind and body with great dispositions able to transition well from the farm to home life. Our dogs are an integral part of our farm and daily life. This creates the ideal environment for our puppies. From birth, they grow in a secure, loving environment where they know that they matter to their family - that they have a purpose.

Tierhaus 23 reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Colorado Mountain Dogs.
Hip Dysplasia
Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.
DNA Disease Panel
Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).
Health testing is one key piece of responsible breeding and is performed on breeding dogs to prevent the presence of heritable conditions in their puppies.
