Have you ever noticed that your furry friend’s feet have an odor-like smell, especially when they’re tired? If you’re a pet owner, you may have encountered a popcorn smell—sometimes a cheesy scent—and are wondering if this is perfectly normal or if there’s an underlying condition.

The good news is that it’s common for dogs’ feet to smell like popcorn, and it’s caused by bacteria. It’s actually a sign your pet is healthy.

Do Dogs’ Feet Actually Smell Like Popcorn?

Dogs’ feet provide the perfect environment for bacteria and yeast to reside, as there’s lots of moisture with minimal air circulation within the pockets of their toes and foot pads.

Microorganisms, including the Pseudomonas bacteria, find their way onto your fur bay’s feet because your dog is actually in good health, not for the opposite. In fact, if your pet is hygienic and well, their fur (feet, in particular) likely becomes a breeding ground for around one trillion bacteria.

Microorganisms emit a distinctive odor that people refer to as a popcorn or cheesy. If the smell is sweeter and fruitier and close to popcorn, it could be the Pseudomonas bacteria.

Furthermore, as humans sweat through their armpits, pets sweat through their paws. So often, this popcorn smell is nothing more than bacteria and microbes in between their toes. This smell might become stronger when your pet is sleeping.

Can a Popcorn Smell Be a Bad Sign?

Most times, there’s nothing to worry about. But it’s worth bearing in mind that dogs spend all day on their feet and walk outdoors, so they’re prone to picking up dirt, bacteria, and debris that can cause dirty, poor-kept feet. Of course, their feet are padded and designed for these environments, but it can become an issue if their paw pads are injured.

Consider inspecting your dog’s paws to see if there’s inflammation, discharge, a cut that won’t heal or an unpleasant, foul smell. If you notice any of these symptoms, contact your veterinarian to ensure it’s nothing serious or to obtain treatment.

We mentioned that a popcorn odor is common and normal, but if you notice the smell is getting worse, you should also check for the following symptoms on their paw pads:

  • Cracked toenails
  • Flaky skin
  • Hair loss
  • Limping or preferring to walk on other legs

A pungent odor could mean that they have an infection in their nail bed, an injured toenail, a foreign body (like grass awn), or an overgrowth of microbes on the paw pads that can lead to a fungal infection.

Can You Stop Dogs’ Feet From Smelling Like Popcorn?

While a popcorn smell isn’t a sign of poor health, we appreciate that not every pet parents want this aroma. If this sounds like you, here are some ways to eradicate the smell and keep their paws clean and healthy:

  • Wash your pet often, paying close attention to their paws and in-between the paw pads.
  • Keep their feet dry (use a towel if they’re exposed to water) to prevent harmful bacteria from growing.
  • Trim long fur accumulated on their paws and feet.
  • Wash their feet after they’ve walked in muddy, dirty, or wet environments.
  • Invest in pet boots to make them less susceptible to injuries or if they have a cut that’s not healed yet.


What causes the popcorn-like smell in a dog’s feet?

One common explanation is that it is related to the presence of bacteria on a dog’s paw pads. Specifically, some types of bacteria can produce a compound called S-methyl thioesters, which has a scent that is often described as similar to popcorn or corn chips. In some cases, the odor may also be related to the accumulation of sweat or other debris on a dog’s paws.

Is a popcorn-like odor from a dog’s feet always normal?

While some dogs may naturally have a slight popcorn-like scent to their feet, it is important to note that persistent or unusually strong odors may be a sign of an underlying health issue.

For example, if a dog has an infection or other issue with their skin or paws, it may produce a more intense or unpleasant odor. In general, it’s a good idea to keep an eye (and nose) on your dog’s feet and speak with a veterinarian if you notice any concerning changes.

Can I get rid of the popcorn odor from my dog’s feet?

If you find the popcorn-like smell from your dog’s feet unpleasant or concerning, there are a few steps you can take to try to mitigate it. Regularly washing your dog’s feet with a gentle, pet-safe shampoo can help remove any buildup of bacteria or debris that may be contributing to the odor.

Additionally, drying your dog’s feet thoroughly after baths, walks, or outdoor play can help reduce the risk of moisture buildup that can lead to bacterial growth. If you are concerned about your dog’s foot odor or notice any other symptoms or changes in their behavior, it’s always best to consult with a veterinarian for personalized advice and guidance.


Popcorn odor isn’t usually anything to be concerned about, as it’s a result of healthy bacteria living in your pet’s paw pads. However, take proper care to keep your pet’s feet healthy to prevent infections by regularly washing them and drying them after they’re exposed to dirt, mud or water.
