I've been meaning to do this for awhile! After being basenji-less for over 20 years, we recently adopted a 9 yr old girl from BRAT. Pippi is wonderful and we feel so lucky to have found her.
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.
I live near the mountains in Colorado. There are some great trails with open space all around to let thme run around.
Gosh I'm so jealous!! We don't have any plasce we could let our pooches loose. I would love a big open space sans any basenji prey :) that way they'll come back
