Harris first became smitten with Maggie while driving the abandoned dog, who was covered in ticks, from the reservation where she found her to an animal rescue shelter.

'I was going to drop her off at the Humane Society, and, on my way there, I put her in this bucket in the front seat and she stared at me while we drove for hours,' she told the New Yorker.

Since that first journey that convinced Harris to keep the dog, Maggie's adorable look has been a constant source of inspiration. Since the pair began their U.S. road trip in March they have already covered more than 29,000 miles - and taken in attractions in New York, Tennessee, Texas and Nevada.

Harris, who was born and raised in Canada, said part of the reason behind the trip was to see more of the U.S. while she was applying for citizenship.

The photographer has gathered a strong following on Instagram, where she keeps fans updated on her and Maggie's travels. She also intends to create a book - Dog Bless America - from her images.
