i have a working cocker not a show cocker i cant enter her  in any shows can i

If she's Kennel Club registered you can enter her, but working cockers are very different to show cockers so it's not worth entering her in anything other than 'Companion' shows.

As you will find out Working & Show cocker are like two diff breeds, temprement, health etc. I wish the KC would register as such. you will have lots of fun with your new pup if you can keep up with her! enjoy.
