Siân Brooke, who will play Dorothy, told the Times of London she is worried that Bobby, the West Highland Terrier, might upstage her.
The original Toto (left) was a Cairn although many mistakenly believe he was a Scottish Terrier.
Over the years there have even been rumours that Toto was supposed to have been a Dachshund, but lost the role due to anti-German sentiment.
Break a leg, Bobby. We’ll be waiting for the reviews after opening night next week.
Update: The reviews are in and Toto’s the star of the show.
