Is Incense Bad for Dogs? 7 Surprising Truths Every Dog Owner Must Know

🪔 Understanding What Incense Is

Incense is a mixture of aromatic plant materials and essential oils, commonly used in many households for religious, spiritual, or relaxation purposes. It typically comes in the form of sticks, cones, or coils that, when burned, release fragrant smoke.

🌿 Common Ingredients in Incense

Incense is made from a mix of different ingredients, which can vary quite a bit depending on the type and purpose.

  • Resins: Like frankincense and myrrh
  • Herbs: Such as sage, lavender, and sandalwood
  • Essential oils: For fragrance and therapeutic effect
  • Binders and accelerants: Sometimes synthetic, for stability

While these ingredients seem natural, some can be toxic to pets, especially when combusted.

🏠 How Incense Is Used in Homes

Incense is usually burned for:

  • Religious rituals
  • Meditation or yoga practices
  • Removing bad odors
  • Creating a peaceful ambiance

However, burning incense indoors poses a potential health hazard to dogs due to their sensitive respiratory systems.


🐶 Can Dogs Smell Incense Differently Than Humans?

Absolutely! Dogs have an incredibly powerful sense of smell—around 40 times more sensitive than what we humans experience. While a subtle scent may seem pleasant to you, it might be overwhelming—even painful—for your pup.

👃 Dog Olfactory Sensitivity Explained

Dogs have over 300 million scent receptors in their noses, compared to 5–6 million in humans. This makes them incredibly sensitive to airborne particles, including smoke and fragrances.

😖 Why Scented Products May Be Overwhelming for Dogs

What smells “relaxing” to you might cause:

  • Disorientation
  • Sneezing
  • Head-shaking
  • Avoidant behavior

Especially in small dog breeds or dogs with pre-existing health issues, even short exposure to incense can be distressing.


⚖️ Pros and Cons of Burning Incense Around Dogs

Let’s break down the pros and cons of incense exposure for dogs:

✅ Pros: Calming Effects (For Humans)

  • Helps you relax, which can indirectly affect your dog positively
  • Used for spiritual or cultural reasons
  • Temporarily removes bad odors

However, the benefits don’t extend to dogs directly—they often pay the price for our peace.

❌ Cons: Respiratory and Neurological Risks

  • Smoke inhalation can cause coughing or wheezing
  • May trigger seizures in dogs with neurological sensitivities
  • Can worsen existing respiratory conditions, like collapsed trachea
  • Contains toxic compounds, such as benzene or toluene

Important: Dogs can’t verbally express discomfort, so symptoms often go unnoticed until they become serious.


🚨 5 Harmful Effects of Incense Smoke on Dogs

Here are the most documented ways incense can affect canine health:

1️⃣ Respiratory Irritation and Coughing

Breathing in incense smoke can irritate your dog’s airways and cause problems like:

  • Coughing
  • Sneezing
  • Shortness of breath

Especially harmful to puppies, seniors, and brachycephalic breeds (e.g., pugs, bulldogs).

2️⃣ Worsening Asthma or Allergies

Dogs with allergies may show increased symptoms when exposed to incense:

  • Itchy skin
  • Red eyes
  • Ear infections
  • Reverse sneezing

3️⃣ Toxic Ingredient Inhalation

Burning incense releases:

  • Carbon monoxide
  • Formaldehyde
  • Polycyclic aromatic hydrocarbons (PAHs)

These substances can cause organ damage over time with chronic exposure.

4️⃣ Eye and Skin Irritation

The smoke and chemicals can irritate:

  • The eyes, leading to excessive tearing or squinting
  • The skin, especially in sensitive breeds

5️⃣ Behavioral Changes Due to Discomfort

Some dogs may become:

  • Restless
  • Anxious
  • Aggressive
  • Depressed

This can be a reaction to unidentified stress from the smell or sensation of the smoke.
