Why Does My Dog’s Breath Smell Bad?
With how common bad dog breath is, you might have believed it’s normal and there’s not much you can do about it. However, it’s not normal if your dog has bad breath.
What causes bad breath in dogs? There are a few reasons why your dog might have bad breath. Some of the reasons might even surprise you.
The first reason your dog has bad breath comes from their diet or allergies. What you feed your dog could affect their breath. For example, table food causes bad breath and could affect teeth and gums.

In some cases, your dog might be allergic to ingredients in their dog food or certain table foods. Food intolerances often cause health ailments, like diarrhea, along with the bad breath. Luckily, there are ways you can prevent bad breath.
In cases where your dog seems normal but just has bad breath with their diet, you can change it and wait a few days. Alternatively, if you just changed it, you may have to wait a few days for your dog to adjust, provided they don’t have any health problems with the new diet.
In many cases, the reason your dog has bad breath is from dental or gum issues. Mouth conditions like gingivitis, periodontal disease, abscesses, ulcers, or cavities can contribute to bad breath in dogs.
Pet owners often don’t think to take care of gums and teeth in pets. It’s not mainly their fault, treats and toys often make claims to care for them without any dental intervention. Pet owners should keep in mind that certain breeds are susceptible to dental problems.
Another reason for bad breath in dogs is a medical condition. Sinus problems, lung issues, and throat problems commonly cause bad breath. Additionally, foreign objects trapped in the mouth, throat, or stomach can release odors too.
Underlying health issues typically present with other health problems, like reduced appetite, jaundice, vomiting, or specific characteristics of their breath. For example, urine scented breath may indicate kidney dysfunction. Some skin diseases that form around the mouth can occur in any breed of dog. This can cause an unpleasant smell and seem as though it’s your dog’s breath when it’s their skin.
We all know how dogs can get, especially when they’re puppies. They have a habit of getting into everything and chewing on what they can get their mouth on.
Unfortunately, this sometimes leads to them getting into the trash, eating their own poop, eating dead animals, or even getting into the cat litter. If their diet, allergies, and health conditions have been ruled out, it’s a good chance they’re eating something causing the bad breath.
