Ewan McGregor has had many love interests but none have touched him as much as his canine co-star Cosmo in his latest film Beginners. McGregor tells host Robin Milling how he bonded with the pup wanting to take him home after the shoot, only to find his wife was allergic to hairy dogs! "I did find a little rescue dog on the last day of the shoot called Sid who’s my dog now. I still see Cosmo now and again with Sid. He’s like a Cosmo replacement because he’s the same size and white so it’s like having Cosmo around and my wife isn’t allergic to Sid so he’s a real member of the family."
