An intruder stormed the arena as the winner of the Crufts dog show was announced on live television.
The man, who was named by Crufts organisers as a protester from the animal rights group Peta, was wrestled to the ground in the middle of the show arena, the NEC in Birmingham.
Ms Short quickly grabbed Tease as several men ran down and cornered the protester in front of a startled live audience.
The crowd broke into applause as the intruder was taken away.
Crufts and the NEC Group said they would review security procedures as “a matter of urgency” as the scare had frightened the dogs and risked their safety.
A Crufts spokesman said: “It appears that protesters from Peta gained unauthorised access to the ring in the main arena at Crufts, and in doing so scared the dogs and put the safety of both dogs and people at risk in a hugely irresponsible way.
“Our main priority at the moment is the wellbeing of the dogs that were in the ring, who are looked after by their owners and show officials.
“The NEC Group have extensive security procedures in place at Crufts and we, along with the NEC Group, will be reviewing what happened as a matter of urgency.”
It said there were two intruders and named them as members of the Vegan Strike Group, which bills itself as fighters against animal abuse.
