What you are smelling is not actually “doggy breath” – it is Bacteria Breath.
The foul odour from the mouth is composed of Volatile Sulfur Compounds (VSCs) – these are waste products made when certain types of bacteria digest sulfur-containing proteins.
The bacteria responsible are anaerobic – that is to say they grow in the absence of oxygen. But isn’t the mouth a pretty airy place? Well, yes and no:
- Bio-film bacteria – in this case, the bio-film is plaque – are oxygen-scarce in the middle at a thickness of only 0.1-0.2 mm thick.
- Pockets around teeth are oxygen-scarce – and the worse the dental disease is, the larger the pockets are and the more stinky bacteria can be grown.
Ninety percent of the VSCs produced are:
- Hydrogen sulfide – the smell of rotten eggs
- Dimethyl sulfide – the smell of rotting fish
The next big odour contributor on the list:
- Methyl Mercaptan – the barnyard/feed-lot smell.
- Cadaverine – Smell found in urine and in decaying meat.
- Putrescine – Rotting meat smell
- Skatole and Indole – found in fecal matter.
- Proprionic and Isovaleric acid – Sweat and sweaty feet smell.
- Butyric acid – found in vomit.
- Pyridine – Unpleasant fish-like odor.
