How to Recognize Diarrhea in Dogs

Diarrhea refers to loose, watery, or unusually frequent bowel movements. It can vary in consistency, color, and smell, depending on the cause. Some episodes resolve within a day, especially if linked to a minor dietary issue. However, others may signal something more serious.

Types of Diarrhea to Watch For

• Acute Diarrhea: Sudden onset, usually short-lived. Often caused by stress, dietary indiscretion, or parasites.
• Chronic Diarrhea: Persists for weeks or recurs often. Can stem from inflammatory bowel disease, food intolerances, or underlying health conditions.
• Small Bowel Diarrhea: Large amounts of loose stool, often less frequent.
• Large Bowel Diarrhea: Smaller amounts, increased frequency, and urgency. May include mucus or straining.

When is Dog Diarrhea an Emergency?

While many cases of dog diarrhea resolve on their own, some require immediate veterinary attention. So, when is dog diarrhea an emergency? The answer depends on your dog’s overall health, age, and the presence of other symptoms.

Red Flag Symptoms That Warrant Immediate Care

If your dog shows any of the following signs, call Veterinary Healthcare Associates at (863) 324-3340 or seek emergency veterinary care right away:

• Lethargy or weakness: If your dog seems unusually tired or unable to stay awake, it may signal dehydration or a systemic problem.
• Blood in stool: Bright red blood or dark, tarry stools can point to internal bleeding or serious gastrointestinal disease.
• Vomiting: When diarrhea and vomiting happen together, dehydration can set in quickly, especially in puppies and senior dogs.
• Fever: A rectal temperature above 103°F may indicate an infection or inflammation.
• Abdominal pain or bloating: Dogs in pain may whimper, guard their belly, or assume a prayer-like posture.
• Ongoing diarrhea for more than 24–48 hours: Especially concerning if there’s no food or water intake.
• Signs of dehydration: Dry gums, sunken eyes, and loss of skin elasticity are signs your dog may be dangerously dehydrated.

In these cases, waiting it out at home is not the right call. Fast action could prevent a serious health decline.

Common Causes of Dog Diarrhea

Understanding what might be behind your dog’s diarrhea can help you respond appropriately and know when to involve your vet.

Dietary Indiscretion

Dogs are notorious for eating things they shouldn’t. Garbage, spoiled food, or foreign objects can all cause stomach upset. While mild cases may resolve quickly, ingestion of toxic substances can become life-threatening.

Parasites and Infections

Worms, giardia, coccidia, and bacterial infections like salmonella can all trigger diarrhea. These are especially common in puppies and dogs in crowded environments such as shelters or boarding facilities.

Dietary Changes or Sensitivities

Sudden changes in diet or food intolerances can lead to gastrointestinal upset. If you recently introduced new food or treats, this could be the culprit.

Chronic Conditions

Long-term digestive issues may result from conditions like:

• Inflammatory bowel disease (IBD)
• Exocrine pancreatic insufficiency (EPI)
• Food allergies
• Liver or kidney disease
• Cancer

If your dog has been experiencing on-and-off diarrhea for weeks, diagnostic testing may be needed to pinpoint the underlying issue.

What to Do Before Heading to the Vet

If you suspect your dog’s diarrhea is an emergency, call Veterinary Healthcare Associates at (863) 324-3340 immediately. But while you prepare for the visit, there are a few things you can gather or observe that will help your veterinary team:

Bring a Sample if Possible

If you can, collect a fresh stool sample in a sealed plastic bag. This can help with testing for parasites, bacteria, or other abnormalities.

Make Notes on Symptoms

Document your dog’s symptoms and behavior, including:

• When the diarrhea began
• Stool consistency and color
• Frequency of bowel movements
• Any vomiting, lethargy, or other symptoms
• Diet and recent changes
• Access to potential toxins (e.g., trash, cleaning chemicals, medications)

These details can significantly speed up the diagnostic process.

How Diarrhea Can Affect Puppies, Seniors, and Small Breeds

Age and size can influence how dangerous diarrhea becomes. Young puppies, senior dogs, and toy breeds dehydrate quickly and often lack the reserves to handle prolonged gastrointestinal distress.

Why Puppies Are at Higher Risk

Puppies are still building their immune systems. Diarrhea caused by parasites or viruses like parvovirus can escalate rapidly. Because they’re small and fragile, dehydration or electrolyte imbalances can happen within hours.

Senior Dogs and Underlying Illnesses

Older dogs may have compromised organ function or other chronic conditions that make it harder for them to recover from fluid loss or infections.

Small Breed Concerns

Tiny dogs have lower body reserves and can spiral into dehydration or hypoglycemia faster than larger breeds. Always treat diarrhea in small dogs as potentially serious.

How Vets Diagnose the Cause of Diarrhea

Our veterinarians in Winter Haven take a thorough approach to diagnosing diarrhea, especially if it’s severe or persistent.

Diagnostic Steps

• Physical exam to check hydration status, abdominal pain, and temperature
• Fecal tests for parasites or bacteria
• Bloodwork to assess organ function and infection
• X-rays or ultrasound if a blockage or foreign object is suspected
• Diet trials or food allergy tests for chronic issues

Treatment depends on the diagnosis. Hospitalization for fluids, antibiotics, deworming medication, or diet changes may all be part of the care plan.

How to Support Your Dog After a Diarrhea Episode

If your dog has been treated for diarrhea, follow your veterinarian’s post-visit instructions closely to help them recover fully. Supportive measures often include:

• A temporary bland diet
• Gradual reintroduction of their regular food
• Medication to ease inflammation or restore gut balance
• Monitoring stool consistency and appetite
• Keeping water readily available

If symptoms return or worsen, contact Veterinary Healthcare Associates at (863) 324-3340 for follow-up care.
