Have you tried 1/2 a people Claritin, once daily? This is what the vet told me to give Milli, and it's working fairly well.
(Benedryl KNOCKED Milli out too, so I didn't want her on that any longer.)
Also, you might try a course of steroids...I know, we all hate to do that, but last summer Emma was having a rough time, and one or two courses of steroids made all the difference-after those got her allergies under control, we were able to go back to Benadryl, and that worked great for her. |
