Hi folks,i could do with stopping my old dog barking,he's becoming a real pain in the arse for it,neighbours are on to me,can't leave him at home in the day or he barks all day and he was barking last night now too,had him from a pup and he's still in pretty good health for 13,so no shooting him suggestions please,but any good advice or any humane device to stop the barking would be appreciated.
