Lilly does the same thing and I was told that it was alergies a while ago. Next time I take her to the vet I'll ask, but she seems to be fine, I meen it doesnt seem to happen more, it's just the spring and summer months. Poor girl! I could use some help with this too I think. I have been giving her a 1/2 teaspoon of Benadril, I was told that that was ok. ??
