What type of hay for a potential allergy?

Hi All,

As some of you may know my bunny Hibby has had a constant infection, please see my other post if you think you could help

But I was just wondering what type of hay you think would be best incase it is an allergy? At the moment they are on Timothy Hay

Thanks for your help x x

Well if he were a horse I would try dust free hay or a hay substitute ie another way to get the fibre, for horses it would be fibre pencils. Not sure what options there are for rabbits, I know you can get dust free hay. Sorry probably not much help!
