My Bear had problems healing his cut cornea. He absolutely hated the cones, the last straw being the incidents with the cone and water bowls. Nothing in the house was safe from his vengeance. As a Jack Russell he’s head strong, full tilt head first into everything. The Rex Specs were the last resort. His eye finally healed which was great as we were at the time frame where they wanted to remove it. The Rex Specs lenses are scarred and battered because his depth perception is off now on that side and he’s still head first into everything but at least now he’s protected.
