It could very well be allergies, maybe environmental... I'm dealing w/the same issue with my Winston! You may want to have a vet check her out, when Winston scratches at his eyes he usually has an eye ulcer that needs medication to heal. Also Winston needs Entropion surgery, it's where the bottom eyelid rolls inward & causes irritation to the eyes. Very common in bulldogs... I use the Greenies Pill Pockets to get Winston to take meds. I can give Winston 2 benadryl tabs, but he weighs 58 pounds. Your baby would need a much smaller dose depending on her weight. Good Luck & keep us posted!!!
