So upon further research, I found some documents showing Dachiu had ADV positive dragons back in 2007, and then their disclaimer and finding people on here that have had problems with dragons they got from Dachiu and on even testing positive, I think it's safe to say Dachiu is knowingly breeding and selling ADV positive dragons.
As for Carolina Classic Dragons, I had looked into them because they are by far my favorite looking dragons, so I asked if he tests for ADV. David's response was: "I no longer test. Way too many inconsistencies and unknowns about this virus. If I ever have a dragon showing any symptoms, I would test but my adult dragons haven't shown any signs of issues in several years. The biggest litmus test that I use is the health of my babies. I know breeders that lose 30%-50%+ of a clutch when infected with ADV. I am fortunate enough to have one of the best exotic veterinary clinics 10 minutes from my facility and they come out annually and inspect my operation. Avian and Exotic Animal Care owned by Dr. Dan Johnson. Dr. Dan will tell you that I take the utmost care in the husbandry of my dragons. Also, Dr. Stacy Wilkinson is one of only a dozen certified reptile vets in the world and she has also visited my facility several times."
So it's great he has top of the line care for his dragons, but he had avoided my answering whether they tested positive or negative, so I asked again and he replied: "Yes, I have owned several dragons over the years that have tested positive for it."
And then quickly sent another in defense: "and with that said... you won't find anyone that has purchased a dragon from me tell you that their dragon hasn't lived a normal, healthy life due to ADV. ADV in young babies causes a high mortality rate. Easy to see"
So. It appears he also knowingly breeds and sells ADV positive dragons.
It really bothers me that breeders would do this. I feel like ADV is the dragon version of HIV/AIDS. It may just be an immunosuppression, but why breed sub-standard dragons? Why risk losing 50% of clutch? Why bring sick dragons into the world and sell healthy looking ones, that still carry it and may yet suffer from it, to unknowing people. It's irresponsible and cruel. I understand that not much is known about it, and it doesn't have to be a death sentence, but no vet or scientist in the world would recommend breeding an ADV positive animal. If you have an ADV dragon, then give it the best life you can, but don't go breeding it and spreading a virus.
This post/topic is not meant to flame anyone, but for the life of me I could not find a place of reviews for breeders, and I think most people don't even know about ADV. I just wanted to say that at least these 2 breeders have admitted to breeding and selling ADV positive dragons. People have a right to know. I think a list should be created of breeders who have infected colonies and breeders who have clean ones.
Spice Dragons is SoCal based breeder, and they said they have tested some, but not all of their dragons, but that those tests came back negative. They also keep their babies a little longer before selling to ensure they are healthy (I noticed Dachiu's babies seem to be much younger).
So, just for everyone's info:
Carolina Classic Dragons: Positive for ADV
Dachiu: Positive for ADV
Spice Dragons: Seemingly Negative for ADV
None of this is to say that every dragon at Dachiu or CCD is infected, or that it is impossible to get a negative dragon from them. I just wanted to put the info out there so people can make their own educated decisions and take their own risks.
