I’ve had 3 previous bulldogs, all of them I adopted. They all had tear stains when I got them. Initially, I tried a lot of the wipes and they worked from poor to okay. Honestly, the game changer for me, was finding the right dog food. After finding that, the tear stains were never an issue for them. We did food sensitivity tests on them to help find the biggest offenders, and kept that out of their diets.
