Welcome to the forum. It's good to read the posts from breeders that appear here, because all your suggestions and information is welcome to all of us non-breeders.
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.
My heart breaks reading your wonderful story of Dinah - it is so clear she is a huge part of your heart -you will have such wonderful memories of her when it is her time to give up the pain. I also do not believe dogs don't have souls - of course they do - the unconditional love they give, the way they try to help when you are emotionally suffering, the joy they get when they see you coming after a separation - all these and more are proof they are very soulful. A loving companion dog is God's gift. All our hearts are with you, and our tears flow with yours. God bless.
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.
