I haven't seen all the entries but from what I have that standard poodle has a good chance (wouldn't be my choice). Boxers are my favourite dog but they never ever are a group winner these days.
We used to have a standard Poodle, wonderful dog. Sad they have to be trimmed like that, but the cut was well explained. Ours only ever had a short back and sides!
Mine had one too Tony. A toy apricot poodle. Went by the name of Flint.(don't ask!) Mother would cook liver for the dog but not for my father who loved liver. Dog would bite most people but her. My cat Trixie loved teasing the dog.
