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.
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'.
