One problem that I have ran into with my basenji is that she always seems to have fluid running down from hear tear ducts leaving her with a sad look.:( She also was rubbing her eyes a lot with her paws and seem to be blinking constantly. This happened especially during the spring time. I know that these dogs alerady have eye problems and I also wanted to prevent any long term damage this could be causing. I bought a couple of portable air filters from iaq source. and put them into the areas where I keep her. These seem to help a lot and give my dog a much better look. I would think healthy looking eyes would give you an advantage in a show. As a bonus they also seem to help out with my allergies as well. I hope this helps!:cool:
