Hi again Karrie - why don't you
Register with the site and then we can get a conversation going? (Fingers crossed that link works ;)!) It's free, and you too could become addicted as we all are.
Only suggestion would be to go down at least one size on what they recommend for an adult Border Collie, but I'd suspect at 28lbs you'd need to go down more. My girl that I bought the Halti for in the Westie size weighs in at 38lbs, and is a bit shorter-headed than your average Rough, but it's all to do with the head length as well as width.
Don't you have a 'Pets at Home' type pet superstore locally, they're normally fairly reliable for Haltis and the like?
