I had one rescue Basenji whose eyes were teary but they weren't bothersome to her. We have a fake Basenji now whose eyes are teary due to clogged tear ducts, the vet has unclogged them but they just clog up again. Doesn't seem to bother him. There used to be a product that you could sprinkle on their food every once in a while to prevent staining and it worked . But it was banned.
Where are you? There is a pretty tri in a MO Humane Society right now. They declined BRATs help, and she's a blind senior so I want a Basenji savvy home to get her. https://www.adoptapet.com/pet/28093472-columbia-missouri-basenji?utm_campaign=NewPetAlertFR-910&utm_medium=email&utm_source=NewPetAlert&utm_term=petId%3A28093472,placement%3A2&fbclid=IwAR0j-bgZUmAQcq4hO5JpErTIDQdLCxTdyq0z7OuD4jwbUCEB2eEdNB-PgjE
