The Detroit Free Press reports an agent with U.S. Customs and Border Protection delivered the new dog to nine-year-old Joseph Wilcken over the weekend.
The Waterloo, Ont., family's previous dog, Ash, got loose Dec. 21 at the Ambassador Bridge.
A U.S. customs agent ran down the bridge ramp in pursuit of Ash, followed by Joseph's father, Niels Wilcken.
Joseph's mother, Ana Wilcken, says the new dog -- Coco -- is the same kind of dog as Ash, a Jack Russell terrier and pug mix.
She says her son was very upset through the holidays, but now is "so happy."
