Jan Brown, 52, runs Knitted With Love, an online store she created in 2008 to sell hand-knitted hats and sweaters for dogs.

She began knitting sweaters to raise money and awareness for greyhound rescues, according to her website.

In 2013, Brown started knitting  full-time after her husband suggested she leave her job to devote herself to the business.

She said she does it for the animals.

"There are so many dogs that won't be rehomed this Christmas so for many of them, it's the only gift they will get," Brown old The Mirror.

It takes Brown up to 20 hours to knit each sweater, which she sends to pet rescue centers across England.
