Health Testing

We take the health of our dogs very seriously at Knockout and try our very best to produce the soundest healthiest chihuahuas possible.

In accordance with recommendations of the Chihuahua Club of America and The American Kennel Club Breeder of Merit program we participate in, all of our breeding dogs are screened and registered with the OFA for cardiac, patella and eyes.

Additionally we have begun the process of EMBARK DNA testing our dogs for over 160 genetic diseases. We believe that health testing is about INFORMATION so that we make the best choices possible in each litter we produce. Embark DNA is another way for us to get more information about our dogs.


ASK your breeder to see health clearances for dogs if they are not in the database, which is easily searchable. Breeders who care about the breed publish these results.

Whenever possible we utilize the opportunity to have the Advanced Cardiac Clearance done for our dogs. This is a step above the regular required OFA cardiac clearance that is required for the breed. This exam is performed specifically by a board certified cardiologist.

We offer a 2 year health guarantee against life threatening genetic defects for each puppy that we sell. By testing your puppy's parents for known genetic problems that occur in the chihuahua breed, we feel you have a greatly increased chance of a healthy puppy that can live a full normal life. 

Each dog's results are posted on their individual page if they are part of our breeding program. Some dogs may not have completed results posted yet due to age (chihuahuas must be a minimum of one year of age to have their results certified) or not being part of our breeding program yet, but any dog being used for breeding will have completed results available.
