Dog growling - but not aggressively

[ahlam1399]

Before I take my dog to the vet with the only symptom as growling, just looking for a bit of advice. My dog has suddenly started growling, well more grumbling, when he?s at work with me. It?s not aggressive, there?s no snarling. Half the time he?s on his back wagging his tail whilst doing it. He doesn?t do it at home, only in the office. He?s not obviously unwell or in pain either. He? been coming to work for over a year and nothing has changed in the office so can?t think why he would be stressed.I?m absolutely stumped! Can dogs just growl for no real reason?
