Hi Doc Jones! I have a question about my 4-year old Pit/Lab mix. He doesn’t do it at a time when there would be sun in his eyes. It always happens when he’s inside and wrinkles up his whole little face when he squints. I read that it could be a health issue that could cause blindness if not treated but it could also be signs of other things like allergies. What, if anything, can do for him as far as herbs or is it something I should be worried about? Thank you!!
