Pedigree SelfieStix. A specially designed phone accessory that attaches a DentaStix to any phone, so you can capture the perfect dog selfie every time. SelfieStix was free with every purchase of Pedigree DentaStix and was supported by a campaign and app. The SelfieStix app uses a machine learning network to recognise the faces of different dogs, allowing owners to add fun and quirky filters to their beloved pooch. (http://www.colensobbdo.co.nz)
