Its true. I would just make sure you get the test. Now that there is a NEW DIRECT TEST!, you wont have to wonder if it is probably clear, carrier, affected, or indeterminant. It WILL be Clear, Carrier, or Affected. So when you get your basenji tested, you will know for sure. Puppy mills and pet stores are kinda scary for fanconi because majority of them dont test. But its true, everyone starts out somewhere and now that you are here, you will have alot of basenji people with knowledge to help you through everything. Ill be there if you need me :)
Welcome to all of you! Nice combination of dogs to have - a basenji and a vizsla.
I agree with Sharron - please get your basenji tested for Fanconi. Don't get scared of doing the test. Test with the idea that you are doing it to prepare your basenji with the best health plan available.
