I love these dogs. My current baby turned 11 years old in December. Her name is Mattie and she is the love of my life. She is tri-color. I got my first Basenji in 1977 (red & white) "Nicki". Mattie is my fourth.
Bungwa has a very dry mouth and I only managed to get a very tiny white patch on the test card but it was still sufficient to do the test with that. It only turns white when it's dry - the instructions are quite explicit. Of course as Pat says it could be a bad test form.
Hello & welcome from Canada. Hope you find the perfect match for your home. There is a lot of great info here, & you can spend days just doing your 'homework'.
