According to Bayer, it's good until the Rapture. I'm sure that it's fine to
use on your dogs in that it isn't going to make them sick or anything along
those lines. However, it might be a little less efficacious than new
product. If you do use it, I'd just keep a closer eye out for parasites,
but the likelihood is that it'll work just fine.
