While it is a chronic problem for millions of humans, bad breath can also take a toll on man's best friend. According to an article in the UK Daily Mail, a rescued greyhound in Essex has been overlooked by more than 300 potential owners for one simple reason - he has halitosis.
Tommy the Greyhound, who is currently looked after by caretaker Elaine Sheppard, has bad breath that was originally caused by an immune system problem. The news source said that the canine was put on a course of antibiotics to boost his immune levels and treat a gum infection, but the therapy did not rid him of his bad breath.
The dog uses mouthwash, which he has been trained to gargle, once a day. The newspaper notes that his rinse is very different from the human variety, which could be toxic to pets.
Few humans have as bad from a case of halitosis, but the basic issue is the same. Oral odor originates with bacteria in the mouth, which multiply when the gums and tongue are dry, infected or coated with food. These microbes create the compounds that give bad breath its smell.
Giving dogs some carrots or brown rice may dampen their halitosis, though brushing their teeth regularly is a better preventive measure, says CBS News. Beyond brushing, humans may look into purchasing specialty breath freshening products online.
