Taking my friend's dog to Birmingham for her and she wants me to try him in the GC bronze test they apparently are holding. If by some miracle he passes, presumably he'll still be eligible to do GC classes at shows with her, it won't matter that I was the handler for the test?

As long as the dog gets it it doesn't matter who handles it :)

Excellent thanks. Perhaps I can get them to put her name on the cert as owner, but I doubt he'll do his stays for me anyway so we probably won't have to worry!
