@marinaamz29 I absolutely recommend looking into the Functional Dog Collaborative. They have a website, podcast, and Facebook Group. It is extremely informative and will help you learn a lot about why it is important to breed dogs ethically.
Genetic tests are great to have, but there are things that a genetic test can not tell you. It can't judge your dog's thyroid, heart, knees, or hips. These require indepth tests that do cost money. Look at your breed club, and they should list the recommended tests for your breed. Nobody can tell if a dog is a good breeding candidate without doing these tests.
There is A LOT that goes into breeding dogs responsibly, and it requires a lot of effort. Overall, your goal should be to reduce suffering in everybody. Some examples are:
.Making sure the puppies you produce are healthy and don't suffer from physical issues.
.Making sure the puppies don't suffer from psychological issues.
.Making sure the people who buy these puppies will take good care of them.
.Making sure the people who buy these puppies have a lifestyle that matches the puppy.
.Making sure none of the puppies you produce end up without a home. You (usually the owner of the female) MUST make sure they chip the puppies and always take them back.
Responsible breeding is hard, so before deciding to do this, look into the Functional Dog Collaborative. They are very informative and amazing. If you have any questions, feel free to ask me.
