Hayfever..

Last summer Rosie, according to the vet, she got hayfever, but how do I know if she's starting again with it? She's perfectly fine at the moment but the only reason I knew last time was because I took her to the vet because her eyes were red and I don't want it to get that far again.
Didnt even realise she could get hayfever till the vet said last year

They can get allergies to anything which is what hayfever is of course. Only way to tell is keep a close eye on her for signs of redness I guess.
