I paid for genetic testing, because I am suspect that the breeder may have known about this dogs problems. I told them about the dogs health problems. This is not the first. And yet, you can imagine my utter shock when I saw that they aren in the process of breeding the father right now. Will this information help my dog? Absolutely not. Will it help me? Yes. My grief is beyond belief. 2 cardiologists have read and reviewed both the echo and the holier. My beautiful puppy has some serious heart problems. And, the fact that the "breeder" chose to ignore me and breed the dog again is irresponsible.
I got onto this group, because I saw a post from 2 years ago from a guest singing the praises of this breeder. She has one of their puppies, that she is planning to breed.
I have learned enough about this disease in the past week, to know that one should move slowly before making decisions to continue this line. This is not a Craigs List dog. This is a supposed reputable AKC registered breeder, who ignored me when I tried to tell them about what was going on with my dogs health.
My tears have turned to anger.
I'm very sorry you are dealing with this. I hope that with medication and the care of a cardiologist you are able to get some quality time with your dog.
As others have said, genetic testing (as in, testing for the two genes identified so far as implicated in DCM) are not definitive in terms of being predictive of DCM. Dogs can test negative for the genetic markers and still develop DCM, or test positive for one or both genetic markers and never develop the disease. At best, the genetic testing at this point is worthwhile for further research, and I'm glad you are helping further that.
The best that breeders can do right now is to study pedigrees for patterns, cause of death, and longevity, and good breeders are doing that. Even so, DCM is in all pedigrees, and can pop up anywhere. A good, ethical breeder will tell you that, will let you know that they've done their best, but that they can't make promises, and will support you should your dog develop this disease.
All of that said, I want to add that a breeder that is "AKC registered" is not a guarantee of quality. The AKC is simply a registry that guarantees a dog is purebred. You'll see dogs of all kinds of quality there. I'm not trying to scold or to put you down, especially in a time when you're dealing with such a terrible situation, but in the interest of education, and especially because there are often those reading along who haven't registered or posted, simply having a breeder be AKC registered really tells you nothing about the quality of the breeder. I'm sorry you've learned this the hard way - many of us have been in your shoes, whether it be health issues, or temperament.
My thoughts are with you, and I hope you'll share both more information with us on the details of the holter/echo info (you have a lot of VERY experienced breed people here who can be a great resource for you), as well as I hope you share the breeder information, too, because someone may end up seeing this before they buy a puppy. You could save someone from making the same mistake you did.
