Emma Watson walked pink dog for charity

Emma Watson walked a pink dog to raise awareness for a breast cancer charity.

The 'Harry Potter' franchise actress was blasted by critics and fans recently when she was spotted taking a puppy out that sported fur dyed in a bright colour.

But the star has hit back at claims of cruelty towards the one-year-old bichon fries, claiming the dog isn't even hers.

She wrote on her twitter page: "Ayeye. Just to clarify one more time that I don't have a dog. @PinkDarcyDog is pink because her owner is raising money for breast cancer."

Groom Dog City owner Stuart Simons assured concerned fans that the treatment he did on the pet was not harmful.

He told website MailOnline: "Pink is our biggest colour, but I do look after another bichon called Casper who comes in for a blue mohican."

He said the beetroot-based semi-permanent dye is harmless and that all the dyes he uses are completely animal-friendly.

He added: "I wet the dog, rub it on like a shampoo, leave it for five minutes and then wash it off. Because Darcy is white, it takes really well. She is a very calm dog, absolutely lovely, and she enjoys her groom."
