If you are fortunate enough to get that lovely, anal gland aroma, then consider your dog gifted. He can empty his own glands, which is actually normal and healthy. Dogs that have problems with their glands are the ones who cannot empty them on their own, either when having a bowel movement or otherwise. If you are worried and he is 'scooting' excessively, then either see a vet or a qualified pet groomer for their advice, but otherwise, I wouldn't be worried. Just keep some baby wipes on hand to wipe his bum when this happens.....
