Cyndi is a joy. Her boxers are a product of the love and devotion she has for them. I flew from South Florida to visit her and experience firsthand the breed she has developed over the past 2 decades. My wife and I have shared our household with boxers for the past 25 years and were rescued by the cutest pup from her Circe after the unexpected loss of our Sadie Lady. It is imperative for us to know the health history of our boxers and from the first interview with Cyndi we knew she was a knowledgeable and trustworthy source. It is also comforting to know she will be there in times of need should they arise. Thank you, Cyndi, we'll definitely stay in touch!
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.
