Stump, the Sussex spaniel recently crowned as Best in Show at this year's  Westminster Kennel Club  Dog Show, eats Purina Pro Plan, according to an  interview  his owner Scott Sommer had with the Houston Chronicle .

"When you put a dog on a food and you think it's working - he has a good coat and skin and is healthy - stick with it," said Sommer.

"All of our dogs eat  Purina Pro Plan . I had a bichon frise, J.R., who won Westminster's best in show, and he ate it, too," Sommer said in the interview.
