Can someone please tell me, if a dog is transferred from person A to person B but person A has entered it at some shows is the dog still eligible for those shows?

eg the dog is owned by person A and entered at shows up to East of England in the ownership of person A. person B then transfers the dog into his name in May and enters the dog in his ownership from Leeds onwards.

Thanks!

Yes they would still be eligible. 

We showed our new dog at Southern Counties on Sunday who was entered in his breeders name but is being transferred into ours at the moment.  All future entries will be in our name.
