You can run as a Vet Handler, and your dog can jump 12".
OR
You can enter the dog as Vet Skilled and she can jump 12".
If you choose the VH route, and are running any other dogs, they will have to jump the VH height as well (i.e., if you're a vet for the weekend, you're a vet for all your dogs!)
Go for it!
