Hello. I have been feeding my EBD the Royal Canin dry food for bulldogs for about 4 months. I am seeing an increase in green glop in his eyes after sleeping and itchy ears- excessive rubbing on carpet/furniture. Also, prior to the food change, he lost fur in two patches on his sides. I am hoping to help him out with suggestions. I have been seeing ads for a supplement for the eye and itch problem. Has anyone tried something like that? Advice welcome, please. TIA
