There are so many reasons, including supporting the long term survival and improvement of the Tamaskan breed as a whole and avoiding buying sickly or underweight puppies which could result in high vet bills.
Some of the reasons why a breeder may not be registered are:
- They do not have true Tamaskan dogs, but similar breed mixes
- The breeder's dogs do not meet the health testing or temperament standards required for breeding (these health risks can be passed on to future generations)
- The breeder broke or refused to meet the rules and ethics set by the registry, which can include things like mistreatment of their dogs, selling sick or underweight puppies, and breeding of dogs with hereditary diseases.
