London, Oct 4: Though dogs have been known for being man's best friend, for a woman in Britain it is her pot-bellied pig for whom she has even built a special bedroom!Maria Cooper, 29, from Kent, is inseparable from her enormous pet -- driving her around, taking her for walks on a lead and letting her come and go through a pig flap, The Sun reported.A music teacher by profession, Cooper loves animals so much that she openly describes her pet pig as her best pal.She says: "I bought myself a black pot-bellied piglet this time last year. She was so cute that I decided to call her Dinky. It was love at first sight and she was much too precious to be kept in an outside enclosure - so I gave her the run of the house." After Dinky grew too big to sleep in her bed anymore, Cooper built her a separate bedroom."I know she's spoilt but she deserves something with a bit of style," says Cooper.As Dinky is treated like a person, she will often be found relaxing in Cooper's boudoir or being kept busy as the star of the show at kiddies' functions.
