Grass and hayfever

gypsy is finally allowed out after having her final 12 week vaccination...so we went to the playing field and had a really good kick about with her favourite football, but she seems to have developed a wheeze in one side of her nose..do dogs get hayfever? and is there anything that she can take? plus we went back today and she started shaking and ran the other way to the concrete groundor is there something more seriously wrong?

I am sorry to hear this, I think dogs can get hayfever from my experience, but I have been assured that piriton is safe for dogs if you wanted to try that.
