Sorry that you have the dubious honour of being the first 2008 grass seed on COL.
I had noticed them this morning too, but Buddy isn't quite as manic about leaping into long grass as some cockers, and his only grass seed was from under a garden hedge on a local housing estate so I just takes me chances I'm afraid!
They really are horrid things. And Buddy is every bit the wuss sensitive little flower, just like Stevie!
