Hi, for one reason kibbys eyes are getting all red and droopy again.. I think she is getting immune to her claritin? I want to try some Benadryl before I take her to the vet and spend another 10000$! She had this problem before and the vet told me it was allergies so I am hoping this will work. I know it's 1 lb per mg , right? Is that twice a day? Kibby is about 43lbs now. I heard liquid is faster, but the oly liquid I see is for kids w/ fruit flavor.. Is this ok? Or are liquid gel pills ok? Generic ok? Or should I try Zyrtec so she doesn't get drowsy... I m looking for faster relief though... She keeps trying to rub her eyes. I do have some neo poly bac too, ok to give? Thanks!
