I no the show ring is for purebred registered dogs but can you show your cross breed as well?
Just think it would be fun and see what she would get.

The guy we got her off of told us who the owners were so I called her and we were told she was a Great Dane/Red Nose pit- funny
have had people ask if she is a Great Dane (cause they can see that in her) and if she had Rhodesian Ridgeback in her.
Even Rhodesian owners said she looked as though she was crossed with one. I really wish I got to see the parents and have asked for
pics but it was her friends dogs and she was selling the pups for them- I don't no. Either was the main thing is we saved her from the
humane society and we Love her!

We have companionship shows in the UK where you can show crossbreeds, don't know about there though?

In the UK the only shows were non pedigree dogs can show is Companion(formerly Exemption) shows but that is only the Novelty classes, such as Waggiest Tail, Best Condition, Best Movement & a host of other classes. There is a number of classes(at least 4 & upto 8) just for pedigree dogs(not needed to be KC registered) at these shows aswell. Quite often they have obedience & agility type events going on aswell at Companion shows..a family fun day out :)
I would have thought there would be something similar over in Canada.

There might be- will have to check into that for sure- just didn't think there would be since
she is not a purebred.
