Puppy Diarrhea: What You Need to Know

By K9Reproduction.com Editorial Updated Sep. 7, 2022

Puppy diarrhea is a common issue that can range from mild to severe, potentially causing concern for any pet parent. Understanding the causes, symptoms, and treatment options for puppy diarrhea can help you ensure the health and well-being of your furry friend.

What to Do if Your Puppy Has Diarrhea

It's essential to determine when puppy diarrhea is an emergency. Immediate veterinary attention is necessary if you notice any of the following signs:

Large amounts of bright red blood or black stool
Liquid diarrhea
Vomiting more than once
Lethargy
Not eating or drinking
Weakness or collapse
Coughing, sneezing, or eye/nasal discharge
Tremors or seizures

If your puppy only has diarrhea but is otherwise active, eating, and drinking normally, you may be able to wait a day or two before seeing your regular veterinarian. However, contact your vet before making any dietary changes or administering over-the-counter medications.

Types of Puppy Diarrhea

Soft Stool

Soft stool is common in puppies and often a precursor to diarrhea. If the stool doesn’t contain blood and your puppy is otherwise healthy, there's usually no immediate concern. Contact your vet to discuss the symptoms and next steps.

Red Diarrhea (Diarrhea with Blood)

Diarrhea with blood can be alarming and may indicate colonic inflammation or a more severe condition like parvovirus or E. coli infection. If there is a slight amount of bright red blood, contact your vet. However, if the blood is significant or the diarrhea is black, seek immediate veterinary care.

Diarrhea with Mucus

Mucus in diarrhea is often due to colon inflammation. While a little mucus is not usually a concern, it’s best to consult your vet if you notice other symptoms.

Diarrhea with Vomiting

Diarrhea combined with vomiting can quickly lead to dehydration, a potentially life-threatening condition. Seek veterinary care as soon as possible.

Yellow Diarrhea

Yellow diarrhea can indicate hypermotility due to inflammation or be a result of a chicken and rice diet. If your puppy is otherwise healthy and the stool is becoming more formed, it's likely not a concern. Always consult your vet if you have any doubts.

Causes of Puppy Diarrhea

Bacterial Infection

Puppies have immature immune systems, making them susceptible to bacteria like E. coli, Salmonella, and Clostridium. These infections can cause severe gastrointestinal symptoms.

Viral Infections

Viruses such as parvovirus, distemper, coronavirus, and adenovirus can be fatal. These viruses cause severe diarrhea, vomiting, and other symptoms. Ensure your puppy is vaccinated to prevent these infections.

Internal Parasites

Common parasites include roundworms, hookworms, whipworms, tapeworms, Giardia, and Coccidia. They can cause diarrhea, weight loss, vomiting, and other symptoms. Regular deworming and fecal tests can help prevent these infections.

Stress

Stress from anxiety, fear, or changes in routine can lead to colitis, causing diarrhea. Minimize stress and provide a stable environment for your puppy.

Food Change or Intolerance

Abrupt dietary changes or food intolerances can cause diarrhea. Gradually introduce new foods and avoid giving your puppy human food to prevent gastrointestinal upset.

Toxin or Foreign Body Ingestion

Puppies are curious and may ingest toxins or foreign objects, leading to diarrhea. Monitor your puppy closely and keep harmful substances out of reach.

Diagnosing the Cause of Puppy Diarrhea

Your veterinarian will ask about symptoms, recent diet changes, vaccination status, and interactions with other dogs. They may perform tests such as:

Fecal ova, parasite, and Giardia testing: To check for parasites.
Fecal smear: To identify bacterial overgrowth.
Viral testing: Rapid tests for parvovirus and other viruses.
Bloodwork: To assess overall health.
Abdominal imaging: X-rays or ultrasound to check for obstructions.

Treating Puppy Diarrhea

Treatment depends on the cause of diarrhea:

Bacterial infections: Oral or intravenous antibiotics.
Viral infections: Supportive care, including fluids and medications.
Internal parasites: Anti-parasitic medications and probiotics.
Stress: Reduce stress and add fiber and probiotics to the diet.
Dietary issues: Remove the offending food, switch to a bland diet, and use probiotics.
Toxin/foreign object ingestion: Treat based on the specific toxin or object, possibly requiring surgery.
