Welcome to you and Tank - we have a sheep named Tank! He's called that because he refuses to move when he's standing in our way! How did your boy get his name?
Welcome and so sorry to hear about the health issues of your two B's…. Thank you for opening up your home to them... And Thank Goodness we now have DNA tests for Fanconi so that no Basenji ever has to suffer with this horrible affliction.
I agree with the others that this is not a common practice among BCOA breeders. I am sorry that this happened to you and yes, you should get your deposit back.
Welcome! This is a great forum to gather information on. Im sure you will be able to find the answers to many questions you may have along with some "b" friends.
