Sienna Miller is a real pet lover and she never lets an opportunity slip when it comes to engage in playful activities with those little pups.

During a film shoot in London, the 25-year-old actress seized the opportunity when she chanced upon a playful puppy.

Sienna had a nice time with the pup and gave it some tummy tickling while the lucky dog enjoyed every bit of it.
An onlooker said:

She made that dog’s day.
