The accolade made it a Crufts to remember for Emily, 33, who joined thousands of other canine lovers in descending on the West Midlands for 127th edition of the world's largest dog show. Security wrestled them to the ground and they were removed from the show.
The Crufts Best in Show award ceremony was disrupted by a "pitch invasion" on Sunday evening, when a protester ran into the arena just as the victor was declared.
Elisa Allen, PETA UK director, said: "Crufts glorifies pedigree fetishists" twisted pursuit of the "perfect' dog'".
Crufts is "a celebration of everything that is wrong with dog breeding it supports and promotes churning out dogs to look a particular way at the expense of their own health".
As the man ran towards Ms Short she grimaced, picking up the dog and holding the dog close to her.
Owner Yvette Short, whose Whippet was named Best in Show quickly moved to protect her dog as the protester headed towards them and the coveted trophy.
The crowd broke into applause as the intruder was taken away.
A Crufts spokesperson said the intruders "scared the dogs and put the safety of both dogs and people at risk in a hugely irresponsible way".
Campaigners for animal rights, said to be from Peta, entered the Crufts arena as the top prize was about to be awarded in protest against "extreme breeding".
"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, an organisation which claims to fight against animal abuse.
