I’m not talking about the dog allergies where humans are allergic to dogs, but where dogs are allergic to something. My little Presley seems to be allergic to the grass in our backyard. About 10 minutes after she goes outside for a while her four paws and ears get really red and irritated. She’ll chew and lick them for hours if we let her and she scratches her face and ears and you can just tell it bothers her. Poor thing, the only thing I know to do is give her children’s strength Benadryl. That seems to help her, the redness goes away for the most part and she stops chewing her paws. I don’t think it’s all the grass that is out there but only a specific weed that’s out there. This started about a month or two ago and that’s about the time we got this annoying weed up by our porch where she spends most of her time. So if anyone has any suggestions on how to get rid of dog allergies they would be greatly appreciated.
