Why Is My Dog's Poop Cold?

As a dog owner, you know that monitoring your pup’s bathroom habits provides important clues about their health and well-being. So when you notice your dog’s poop feeling cold to the touch, it’s only natural to wonder if something might be off.

While there are a few potential causes for your dog’s frigid feces, in most cases there is a simple explanation. By understanding what factors influence your dog’s digestive process and waste temperature, you can get peace of mind or identify when it’s time to call the vet.

Key Reasons Your Dog’s Poop Might Be Cold

There are a few main reasons why your dog’s poop may be coming out cold:

  • Environmental temperature – Poop sitting out in cold weather will cool down to the ambient temperature.
  • Age – Older dogs tend to have lower body temperatures which can translate to colder poop.
  • Illness – Certain viruses or gastrointestinal issues can cause a drop in body temp and colder poop.
  • Medications – Some drugs may lower body temp as a side effect, also leading to colder poop.
  • Diet – Foods or treats that are cold or frozen prior to eating can result in cooler stools.
  • Dehydration – Lack of fluids can cause constipation and overly firm, cold poop.

If your dog’s poop is persistently cold, it’s a good idea to talk to your vet, as it could signal an underlying health problem. But in most cases, temporary colder poop is nothing to worry about.

Why Temperature Matters in Your Dog’s Digestion

To understand why your dog’s poop temperature might fluctuate, it helps to first look at how digestion affects their normal body temperature.

The average body temperature for dogs ranges from 101-102.5°F. This is slightly warmer than humans, who average around 98.6°F.

This extra warmth is due in part to your dog’s faster metabolism. All of the chemical activity that converts food and nutrients into fuel generates heat as a byproduct.

Your dog’s gut flora – the beneficial bacteria in their digestive tract – also plays a role in metabolism and body temperature regulation.

When your dog’s digestive system is functioning properly, their stools should exit the body at close to that 101-102.5°F range.

But certain factors can cause the poop to either heat up or cool down outside the body before you scoop it.

Why Your Dog’s Poop Temperature Changes Outside the Body

Once your dog poops, the temperature of the feces will start changing based on the surrounding environmental temperature.

On a hot day, the poop can warm up and feel hot to the touch. On a cold day, it cools down rapidly.

Here are some specific scenarios where your dog’s poop may register as cold:

  • Long exposure to cold weather – You didn’t pick up poop immediately in below freezing temps.
  • Eating cold foods – Your dog ate frozen kibble or treats which cooled down their digestive process.
  • Drinking icy water – Consuming very cold water affects body temp and exits colder.
  • Pooping in snow – Direct contact with snow will chill poop much faster.
  • Very old poop – If you find poop that’s been sitting for a while, it will be cold.
  • Contact with cold ground – The ground can draw heat out of poop in winter.

So if you notice cooler poop on a regular basis, take note of the weather, your yard conditions, and your dog’s diet and water to pinpoint an external cause.

When Colder Poop Means an Internal Issue

While cooling from environmental factors is the most common reason for cold dog poop, sometimes consistently cold stools point to an internal health problem.

Lower Body Temperature

Dogs with chronically cold poop may have a lower-than-normal body temperature overall. Reasons for this include:

  • Age – Older dogs’ metabolism slows, decreasing body heat.
  • Poor circulation – Certain heart or vessel conditions reduce blood flow.
  • Hypothyroidism – Thyroid issues can lower metabolism.
  • Anemia – Low iron reduces the oxygen in the blood.
  • Sedentary lifestyle – Lack of exercise causes sluggish metabolism.


Some temporary illnesses can slightly lower a dog’s temperature and affect poop:

  • Viral infection – Fevers from flu viruses raise then lower temp.
  • Urinary tract infection – UTIs may cause fever then low-grade fever.
  • Gastroenteritis – Digestive infections can cause hypothermia.

More serious gastrointestinal conditions may also be accompanied by consistently cold poop:

  • Inflammatory bowel disease (IBD) – Chronic inflammation affects digestion.
  • Intestinal parasites – Worms disrupt nutrient absorption.
  • Intestinal obstruction – Blockages prevent proper digestion.

Medication Side Effects

Check with your vet if your dog is on any medication that lists lowered body temperature as a side effect. Common culprits include:

  • Antibiotics – Anti-infectives like aminoglycosides can cause hypothermia.
  • Pain relievers – Opioids and NSAIDs may alter body temperature regulation.
  • Chemotherapy – Cancer drugs impact rapidly dividing cell growth.
  • Anesthesia – Used for surgery, it may take time to wear off.


Without adequate fluids, your dog’s poop can become dehydrated and overly hard and dense. The lack of moisture causes it to feel abnormally cold.

Look for other signs of dehydration like lethargy, sunken eyes, dry gums and skin, and excessive thirst. Encourage water intake if you notice these symptoms.

When To Worry About Cold Dog Poop

As a general rule of thumb, you should contact your vet if you notice:

  • Your dog’s poop is consistently and abnormally cold
  • The cold poop corresponds with other signs of illness
  • Your dog’s poop temperature doesn’t fluctuate normally

Some examples of times to seek medical advice:

✔️ Your older dog’s poop is always cold, and they seem low energy. This could indicate a problem like hypothyroidism lowering their metabolism.

✔️ Your dog is on medication and their poop gets progressively colder over time. There may be a dosage issue to adjust.

✔️ Your dog has gastroenteritis and their poop remains cold after their fever breaks. This points to lingering gastrointestinal inflammation.

✔️ Your dog is drinking more but their poop is hard, dry, and cold. They may have a kidney issue causing dehydration.

✔️ Your dog’s poop suddenly becomes extremely cold. This abnormal change may signify a blockage or other digestive emergency.

While once in a while, cold poop is no big deal, ongoing frigid stools or drastic temperature changes warrant a call to the vet. They can run tests to pinpoint the underlying cause, especially if other symptoms are present.

The Scoop on Healthy Dog Poop

To provide a full picture of healthy dog poop, let’s cover some key qualities to look for:

Normal Color

  • Brown – Shades of brown are considered normal
  • Black – Can indicate blood in the upper GI tract
  • Yellow – This may be a sign of liver or pancreatic trouble
  • Green – This could mean quickly passing or absorbing too many nutrients from grass
  • White – Suggests a lack of bile needed to digest fats

Ideal Consistency

  • Firm but not hard – Retains shape but breaks apart easily
  • Soft serve ice cream – Smoother but not runny texture
  • Log shape – Evidence of healthy muscle contractions

Expected Temperature

  • Warm – Should feel close to your dog’s 101-102.5°F body temp
  • Hot – Can indicate dehydration or prolonged exposure to hot ambient temperatures
  • Cold – Most often due to environmental factors, not always a concern


  • 1-2 times a day – Adult dogs often poop after meals
  • Immediately after eating – Puppies may need to poop more frequently
  • Straining or difficulty – Could indicate constipation or obstruction


  • Digested food – Look for recognizable veggie pieces, seeds, etc.
  • Bile – Liquid that aids digestion, greenish-brown tint
  • Mucus – Small amounts of jelly-like coating are normal but excess may warrant a vet visit
  • Parasites – Worm segments or eggs could be present

Keep these benchmarks in mind as you monitor your pup’s pooping patterns. While variation from the norm is common, substantial or consistent changes deserve a trip to the vet.

Tips for Dealing With Cold Dog Poop

If you determine that the environment or diet is causing those chilly dog droppings, try these tips to lessen the impact:

  • Pick up poop soon after your dog goes to prevent excessive cooling. Set reminders if needed.
  • In winter, put your dog in a jacket or booties before potty breaks to keep their body warmer.
  • Microwave cold kibble or treats for 10-15 seconds to gently warm them before feeding.
  • Add warm water to your dog’s kibble to bring the food closer to their body temperature.
  • Insulate outdoor water bowls or use plastic bottles filled with warm water in winter.
  • Switch from cold tile to carpeted floors in your home during winter months.

With small adjustments like these, you can help moderate the temperature of what goes in your dog to what comes out!

When In Doubt, Ask Your Vet

While perfectly natural fluctuations in your dog’s poop temperature are nothing to fret about, significant or persistent cold stools warrant a trip to the vet.

Some key points:

  • Long term changes – Ongoing cold poop marks a clear deviation.
  • Accompanying symptoms – Consider other factors like appetite changes, lethargy, etc.
  • Medication side effects – Note if cold poop correlates with a new prescription.
  • Age and condition – Senior and unwell dogs are more prone to low body temperatures.

Don’t hesitate to call or visit your vet if your Spidey senses tell you something may be amiss. They can help decipher whether your dog’s frosty feces is due to health or environment.

With a little vigilance and common sense, that brisk brown deposit in the yard is no cause for alarm. Focus instead on all the warmth and unconditional love you get in return from a happy, healthy companion by your side!

Frequently Asked Questions

Is it normal for my dog’s poop to be cold?

It’s generally normal for dog poop that has been sitting out in cold weather to feel cold to the touch. The poop that exits your dog’s body should be near their body temperature of 101-102.5°F. If the poop consistently feels cold regardless of environmental factors, it could signal an underlying health issue.

What causes a dog’s poop to be excessively cold?

Excessively cold dog poop can be caused by: low environmental temperatures, internal conditions lowering body temperatures like hypothyroidism or anemia, viral illnesses, medication side effects, dehydration, or gastrointestinal problems like bowel obstruction or inflammatory bowel disease.

My older dog’s poop is always cold – should I be worried?

If your older dog has chronically cold poop, it may be due to their age-related decrease in metabolism and body heat. However, you should still mention it to your vet, as conditions like hypothyroidism could cause abnormally low body temperature leading to consistently cold poop.

My dog pooped out some yellowish mucus – what does that mean?

Small amounts of jelly-like mucus coating your dog’s poop is normal. But yellowish or excessive mucus could indicate irritation or inflammation in the colon or intestines. Contact your vet if it happens frequently, especially if you notice any straining, diarrhea, or other symptoms.

How soon after eating does a puppy need to poop?

Puppies generally need to poop within 15 to 30 minutes after eating. Their digestive system moves food through at a faster rate than adult dogs. This is normal, but contact your vet if you notice very loose stool or diarrhea associated with the frequent puppy pooping.


The temperature of your dog’s poop can act as an important health indicator alongside other stool qualities like color, texture, and contents. In most cases, finding cold poop simply means it was exposed to low ambient temperatures before you scooped it up. But if their poop is consistently and abnormally cold, don’t ignore it – talk to your vet to rule out potential illnesses or medication side effects. With a little vigilance and common sense, you can rest easy knowing changes in your dog’s digestive system won’t go unnoticed. Focus instead on providing them with good nutrition, proper exercise, love, and regular potty breaks – the perfect recipe for your dog to thrive!
