in the uk can cross breeds do showing agility?

me and my dog lady do loads of local fun shows but i would love to take it a bit further!!! does any one know the answer shes a jack russel x yorkie.

yes you can but I think you need to register on the KC activity register to be able to compete at licenced events.
Yes you can do agility with her and flyball if you want. There is also obedience comps as well as rally obedience. There is also heelwork to music that's really fun to do. Just find a local club to go to first of all and see how she gets on. Well done - hope it goes well.
Yes, But not sure if you have to do a limited registration based on breed, in which case you will have to choose as breed she most looks like and pass her off as such.

Yes you can. To enter Kennel Club sanctioned events you need to register with the kennel club as an agility dog but you don't need to be a pure breed to do this. My advice would be to join a local agility club. They'll be able to tell you more details of what to do and help you in the process. There are also other dog sports that you can enter like flyball and working trials if you fancy a go at them. You can enter a cross breed in any if them.
