What Causes Soft Dog Poop?

First, soft stool in dogs is any poop that does not have a consistent, firm texture and is difficult to pick up. We’ve all been there – trying to pick up mushy or soft stool with a waste bag. It isn’t pleasant, right? Maybe it looks like a smooth ice cream consistency, which could become serious if it progresses to a liquid form like diarrhea.

Some of the more common reasons for if your dog has soft stool include:

  • Dietary indiscretions: From an abrupt change in dog food to eating inappropriate or greasy food, diet plays an important role forming your dog’s stool.
  • Allergens and food sensitivities: Anything that causes your dog’s immune system to react can manifest in their gut. This includes known and unknown food and environmental allergens.
  • Parasites or infection: Worms can cause GI distress, so your veterinarian should screen your dog’s fecal sample during wellness examinations.
  • Stress and anxiety: This includes everything from stress during travel to arguing in the family, loud sounds, and separation anxiety.
  • Medical conditions: If your dog has irritable bowel disease (IBD) or any other ongoing digestive condition, you may see soft poop.
  • Side effects from medications: Medications, including antibiotics or over-the-counter supplements, can cause mushy, soft poop.
  • Ingestion of a foreign object: Even the most astute pet parent may not realize their dog ate a sock, child’s toy, or any number of things. This can become very dangerous very quickly.

Anytime you are uncertain as to why your dog’s bowel movements are irregular, it’s best to call the veterinarian. At the very least, they may want you to drop off a stool sample.

Why Is My Puppy Poop Soft?

Just like their adult counterparts, puppies may occasionally have soft stools. If it is associated with vomiting, lethargy, or any other out-of-the-ordinary symptoms, it’s best to see the veterinarian.

When puppies begin the weaning process from their mother’s milk, their digestive systems are in a period of change. Soft stool in puppies is common at this time. Certain vaccinations, medications, or supplements can cause soft stool, as can too many treats.

Puppies often don’t know their limits when it comes to food. They will eat and often have a ravenous appetite. Too much of a good thing can lead to a dietary bad thing in the form of improperly formed poop or diarrhea.

Everything from an infection to worms, food sensitivities, and stress can alter the state of your puppy’s GI tract. Some puppies may develop giardia or environmental stressors that cause changes in their stool.

What Your Dog’s Poop Is Telling You

You’ll want to examine your dog’s poop from time to time, especially if it becomes soft. Here are key factors to watch for, followed by a list of our top picks for supplements that can help soft dog poop.

Color: The ideal poop color is brown. If your dog has yellow poop, green poop, or anything out of the ordinary, this is abnormal. Blood in your dog’s stool is not normal.

Consistency: Hard poop generally indicates constipation or dehydration, but it can be from a lack of fiber in your dog’s diet. Firm and tubular is the normal. Veterinarians use a fecal scoring system for dogs, and they rank poop on a scale of one to seven. Most dogs should be pooping a “two” on the chart.

Odor: An unusual scent or strong odor may indicate diarrhea, internal bleeding, or something else.

Coating and Visual Inspection: If your dog’s poop is runny, has a mucus-like coating, or shows any signs of undigested food, hair, or flecks of white, rice-like material (likely worms), this is abnormal.

When To Call The Veterinarian About Dogs With Soft Poop

Although most cases of canine diarrhea or soft poop resolve in a matter or hours or days, dogs with consistently loose stool and/or other symptoms should be see a veterinarian.

According to Dr. Meredith Miller, associate clinical professor of small animal medicine at the Cornell Richard P. Riney Canine Health Center, “If a pet stops eating, is lethargic, the diarrhea is black or tarry in quality, there is associated vomiting, or the diarrhea doesn’t resolve in 48-72 hours then veterinary care should be sought.” 

The Overall Scoop on Soft Dog Poop

An abnormal bowel movement has a cause. As pet parents, we must put our detective hats on to determine why there is a change. Each dog is its own unique being, so what may cause soft poops in one dog may cause no reaction in another pooch.

Using a notebook or journal to log in your dog’s bowel movement patterns may be beneficial. Take your mobile along for walks and snap photos if you see any changes or abnormalities. If a veterinary visit is in order, you’ll have images and notes ready to help them in their overall assessment.

The bottom line to help keep dog poop well-formed is:

  • Stick to a diet that works for your dog
  • Limit table scraps and foods that contribute to digestive upset
  • Ask about side effects of any medications or supplements
  • Consider taking your own water along if traveling
  • Don’t allow your dog to drink or eat from other dogs’ bowls
  • Make sure your dog drinks enough and has access to cool, clean water

Regular veterinary checkups and fecal screening can help identify the cause of soft stools and help your dog get back on the road to regularity.
