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?
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.
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.
I sent you a private message with my info (phone number). We can arrange a visit. Also, when the weather cools down I'll let you know and you can come to a basenji pawtee!
