This dad's adorably amateurish pet portraits have raised thousands for charity

Phil Heckels shot to fame when he shared his rendition of the family dog, Narla, on Facebook.

London (CNN)A British man has raised thousands of pounds for charity after his unconventional drawings of people's pets went viral.

Phil Heckels, 38, told CNN that his rise to internet stardom began six weeks ago when he was trying to get his 6-year-old son to make a thank you card for family.
He decided to draw the family dog, a black Labrador named Narla, to inspire his son, and later uploaded a photo of his work on Facebook alongside a jokey caption offering to sell it for £299 (around $390).
    "It was pretty crap," said Heckels, from Worthing, south England, who was surprised to be inundated with offers for the work.
    Heckels has now made around 220 portraits.
    By the end of the day he had seven requests from friends who wanted a drawing of their own pets, and within days his burgeoning reputation saw him inundated with messages and commissions.
