What Causes Bad Breath in Dogs?

Bad breath in dogs is a common issue faced by pet owners in the UK. It is crucial to delve into the various aspects that contribute to this issue to ensure the overall well-being of your canine companion. In this detailed guide, we will explore the underlying causes and preventive measures that dog owners can undertake.


Dental Health

Understanding the dental health of your dog can offer a clear insight into the potential causes of bad breath.

Dental Hygiene

  • Tartar Build-Up: This is a significant contributor to bad breath. Regular dental check-ups can help in addressing this issue.
  • Gingivitis: Inflammation of the gums can lead to persistent bad breath.

Dental Diseases

  • Periodontal Disease: This is a common occurrence in older dogs, where the support of the teeth is affected, leading to bad breath.
  • Tooth Abscess: An infected tooth can produce a foul smell, signaling the need for immediate veterinary intervention.

Dietary Causes

Examining what goes into your dog's diet is pivotal in controlling the issue of bad breath.

Food Choices

  • Low-Quality Dog Food: Often, low-quality dog food can lead to digestive issues, reflecting in the dog's breath.
  • Human Food: Sometimes, the remnants of human food consumed by dogs can lead to bad breath.


Inappropriate Eating Habits

  • Coprophagia: This refers to the consumption of faeces, which is a direct cause of bad breath.

Medical Conditions

Apart from dental issues, several medical conditions can be at the root of bad breath in dogs.

Respiratory Conditions

Professional Interventions
