The little pooch from Glasgow had tough competition from other doggies, but his smooth shiny coat and cute face won the judge's heart.
Danny - whose show name is Dangerous Liaisons - was the smallest in the Best in Show final, after winning best dog in the toy category.
But he managed to keep up with all the other top dogs, including a puffy standard poodle!
The second prize - or Reserve Best in Show - went to Torums Tunde Bayou, a four-year-old Kerry Blue terrier.
Taking it easy
The four-day Crufts competition sees over 20,000 woofers compete to be the prize pooch in lots of different categories.
It's the biggest dog show in the world and probably the most famous. This year it celebrated its 100th birthday.
Danny wins the top prize after almost three years of competition. He is now going to put his paws up, take it easy and retire.
Which in doggie terms, probably means lounging around getting stroked lots and eating all the treats he can!
