A hilarious video has emerged from the US of a dad interrogating his two children after he found a bald patch on the family dog's head. <br /><br />The footage, filmed near Huntsville, Alabama on Monday, shows the father trying to persuade one of his young children to own up, causing a few tears. <br /><br />He later wrote online: "Our four-month-old golden doodle had an almost bald patch on the top centre of her head. <br /><br />"Neither child admitted guilt and we couldn't prove anything." <br /><br />"Earlier in the day my wife found the missing hair and emailed me a picture of it, which was the smoking gun I needed to get a confession," he continued.
