Why Does My Chihuahua Have Bad Breath? (Short Answer)

Why does my Chihuahua have bad breath?

Doggy breath is something we pet parents are mostly aware of and also used to. It is the characteristic bad odor that all dogs’ mouths have.

But if your pooch’s mouth starts producing an odor that is intolerable, then there could be some illness or dental issue affecting your poor guy or girl.

Bad breath or halitosis in dogs can have several root causes. But the three main causes of bad breath in Chihuahuas (or dogs in general) are: poor oral hygiene resulting in tooth decay, dietary or microbiome issues, and/or underlying diseases.

If you have been regular with your Chihuahua’s teeth brushing then it may simply be that your pet ate something from the trash can or just hasn’t had adequate water intake resulting in dry mouth that leads to foul odor.

However, if dental care has been lacking for a while, and you haven’t given a second thought to your dog’s teeth, then you may might want to take action to mitigate the issue.

In the next section, I will discuss in detail the reasons ‘why does my Chihuahua have bad breath?’

Why Does My Chihuahua Have Bad Breath? (Detailed Answer)

Why does my Chihuahua have bad breath?

If your Chihuahua is suffering from bad breath or halitosis, then the following reasons could be responsible:

1. Poor dental hygiene

Many Chihuahua parents forget to brush their pet’s teeth on a regular basis. Sometimes, they think that dogs do not need brushing since, in the wild, no body brushes dogs’ teeth, so why do it at home?

However, we mustn’t forget the fact that we have domesticated dogs and their diets are not exactly the diets of their ancestors – wolves.

In the wild, wolves eat raw meat including raw bones which do not stick to their teeth like commercial dog food does. Commercial dog foods especially wet or canned food tends to stick to the teeth and if your Chi does not drink water afterward or you do not clean its teeth then the stuck food bits could lead to a serious buildup of tartar and plaque on the gums and teeth.

Overtime, this can result in tooth decay and periodontal disease, gingivitis, and other serious oral problems.

Lack of oral hygiene is therefore the number one cause of bad breath in Chihuahuas.

2. Poor diet

The second most common cause of bad breath in Chihuahuas is a poor diet. Dietary inadequacies can lead to poor gut microflora and the bad bacteria that builds up can also lead to a foul mouth odor.

Sometimes, your Chihuahua might also pick food out of the trash can or eat stuff that it finds on the road or in the dog park. This gross habit of raiding the trash can could lead to halitosis.

Then there are some dogs that eat other dog’s poop too and this can cause a really foul breath as well.

3. Underlying diseases

The third common cause of foul breath in Chihuahuas are underlying health issues or diseases:

  • Diabetes – Chihuahuas with diabetes are more likely to develop foul breath because of the sugar imbalances in their bloodstream. The buildup of ketones in the body results in a fruity or ‘alcoholic’ nail-polish remover smell. In addition to having sweet breath, a diabetic Chihuahua might drink more water than usual and also urinate more frequently.
  • Kidney disease – Dogs with kidney disease also develop foul breath because of the high urea levels. This kind of bad breath is typically a fishy smell or ‘urine-like odor.
  • Liver disease – This also leads to bad breath and may be accompanied by yellow eyes, teeth, and vomiting, among other symptoms.

If you suspect any of the above, please consult your vet right away for further treatment.

When Should You Worry About Chihuahua’s Bad Breath?

Why does my Chihuahua have bad breath?

Sometimes, simple oral care, brushing, and administering dental chew sticks or water additives can resolve your Chihuahua’s bad breath issue. For hardened plaque or tartar, your vet might recommend dental scaling procedure or professional dental cleaning which can also show fantastic results.

However, in cases where underlying health issues are the cause bad breath, then you have no option but to seek veterinary treatment.

Below are some indications that can tell you when you should see your vet for your Chi’s bad breath:

1. Sweet fruity odor

If your Chihuahua’s breath is consistently fruit-like or sweet-smelling, it could be a sign that it has diabetes. Is your dog drinking more water than usual? Urinating more frequently? Then it is definitely time to consult your vet.

2. Injury or trauma

Does your dog have a visible dental injury or trauma? Can you see any external swelling under the eye region or on its muzzle? Is your pet pawing its face? Are its teeth rotten? Are the gums swollen and bleeding? Is your Chihuahua having difficult or pain while eating?

Then wait no more and see your Chihuahua’s vet immediately. Sometimes, a thorough professional dental cleaning along with some home care tips are all it might take to resolve the issue.

3. Loss of appetite or vomiting

In addition to bad breath, is your Chihuahua vomiting or showing a lack of appetite? Is it hiding or reluctant to go on its walks? Does it have a fishy breath? Alternatively, is its breath urine-like?

Not always, but most of these signs indicate liver or kidney disease. Please have your vet conduct further tests for an accurate diagnosis and further treatment.
