Question from Sarah Knight:
My Scottie has horrendous breath, teeth are fine, have changed her diet, she also has charcoal on her meals, any other ideas truly welcomed!
Answer: Bad Breath
Hi Sarah, thanks for your question about your dog’s bad breath. To answer it, I’m going to run through the possible causes of halitosis, along with any other symptoms they might show. I’ll then talk about the most likely reasons, and where to go next with diagnosis and treatment options.
Causes of Halitosis
Halitosis, or “bad breath”, is defined as an “offensive odour emanating from the oral cavity”. There are a number of possible causes, some of which are more common than others.
You say you’ve modified her diet, but a lot of dogs (especially terriers!) eat unpleasant things given half a chance – particularly faeces (those of other dogs, horses, livestock etc), or dead and rotting things (often mice or birds found lying in the undergrowth when out on walks). Inevitably, eating anything like this will lead to bad breath.
2) Metabolic disease
We’re particularly talking about diabetes or kidney failure here – both of which can lead to halitosis. In diabetes, the body produces ketones as a fuel supply for the brain, which have a strong smell (with overtones of pear drops – however, not all humans have the gene required to be able to detect this); in kidney disease, the build up of nitrogen waste products in the blood may result in oral lesions and/or smelly breath. In both cases, you’d expect to see increased thirst and possibly weight loss, but the signs can be pretty subtle in the early stages….
