You are here

Who hasn’t given their pet a hug or received a big sloppy kiss on the cheek and noticed an unpleasant odour from their pet’s mouth?

It’s important to know that your pet’s mouth is full of bacteria, so if there is a bad odour, this could be due, among other reasons, to the growth of these bacteria. Bad breath (medically known as “halitosis”) can be a problem and shouldn’t be taken lightly. The first thing to do is determine the cause.

First, it is important to have your pet examined by your veterinarian, just as a person with bad breath would consult the dentist.

What are the different causes of bad breath?

While checking your pet’s mouth, the veterinarian will be looking for the following signs:

  • Tartar
  • Abnormal colour or redness of the gums, tongue, palate or throat (sign of inflammation) 
  • Dental plaque, which could cause a periodontal disease such as gingivitis
  • Condition of the teeth (cavity, broken tooth, loose tooth) or an abscess
  • Lesions or injuries
  • Lumps

Sometimes, bad breath may also have more serious causes such as the following general diseases:

  • Diabetes
  • Kidney failure
  • Respiratory system diseases
  • Digestive system diseases

What treatments are available?

Your veterinarian is your best ally for finding solutions for your pet.

  • If the examination reveals gingivitis, tartar or dental plaque, your veterinarian may then recommend scaling done under anesthesia. This will often resolve the inflammation and bad breath.
  • If it involves a more serious disease, then your veterinarian will recommend other treatment plans adapted to your pet’s condition.

What can be done as prevention?

The first step in resolving bad breath is to take care of your pet’s teeth. Here are some tips:

By taking care of your pet’s teeth, you are making your whole family’s life more pleasant, and this may prevent your pet from having bad breath or developing potentially serious diseases.
