It's ragweed season and my little guy is rubbing his face all over the carpet and furniture. It looks hilarious, but the poor guy can't even scratch himself properly! He literally gave himself a cataract by kicking that side of his face all the time. Sometimes it sounds like he's even hurting himself as he whines while doing it.
Benadryl helps, but it obviously doesn't completely do the trick as he still scratches a fair bit... just not quite as much.
And then he gets dry skin in the winter which also makes him itchy, but at least I can do something about that. He even gets an oatmeal bath every time he gets groomed.
