At Gilbert Queen Creek Emergency Veterinarian and Specialty Center, we see our fair share of urgent gastrointestinal cases. One of the most common reasons dog parents bring their pets to our ER, especially after hours, is diarrhea. It can come on suddenly, cause significant discomfort, and leave owners feeling uncertain about what to do next.
We’re often asked the same question:
“What can I safely feed my dog when they have diarrhea?”
Whether your pet is experiencing mild digestive upset or has more severe symptoms requiring medical intervention, feeding the right diet plays a crucial role in the recovery process. Below, our emergency and specialty team walks you through when to worry, how to support your dog at home, and what role nutrition plays in healing the gastrointestinal tract.
Why Dogs Get Diarrhea
Diarrhea isn’t a diagnosis, it’s a symptom. It can range from mild to severe, and while some causes are simple and short-lived, others may require advanced diagnostics and care.
Here are some of the most common causes we treat in the ER and specialty clinic:
- Dietary indiscretion: ingestion of trash, table scraps, spoiled food, or foreign material
- Abrupt food changes: switching to a new diet too quickly
- Stress colitis: often seen after boarding, travel, or loud events
- Intestinal parasites: including giardia, coccidia, hookworms, or roundworms
- Viral and bacterial infections: parvovirus, distemper, leptospirosis, or salmonella
- Food allergies or sensitivities
- Toxin ingestion: including human medications, plants, or chemicals
- Medication reactions: such as from antibiotics or NSAIDs
- Chronic GI diseases: like Inflammatory Bowel Disease (IBD), Exocrine Pancreatic Insufficiency (EPI), Addison’s disease, or liver disease
- Obstruction: from ingesting a foreign object (toys, bones, clothing)
If diarrhea is severe, bloody, accompanied by vomiting or lethargy, or continues for more than 24 hours, it may require immediate veterinary attention. At our ER, we’re equipped to triage and treat urgent and complex cases around the clock.
Step 1: Fasting – Is It Appropriate?
In healthy adult dogs with mild, non-complicated diarrhea (no vomiting, still drinking, and otherwise normal behavior), a brief fast of up to 12 hours may help settle the GI tract and reduce inflammation.
Fasting should be avoided in dogs who are:
- Puppies under 6 months
- Small or toy breeds prone to hypoglycemia
- Geriatric or chronically ill (e.g., diabetics, heart disease, or kidney issues)
- Already showing signs of dehydration or weakness
- Vomiting in addition to having diarrhea
Not sure if fasting is safe for your dog? Don’t guess, call our ER. A member of our triage team can help you determine whether home management is safe or if your dog needs to be seen.
Regardless of whether food is withheld, hydration is non-negotiable. Always make sure your dog has access to clean, fresh water.
Step 2: Introduce a Bland Diet
Once your dog’s stomach has had a break, or if fasting isn’t advised, it’s time to offer a bland, easily digestible diet. The goal is to minimize GI irritation while providing energy and nutrients for healing.
Here are the home-prepared diets we most commonly recommend:
1. Boiled Chicken and White Rice
- Use boneless, skinless chicken breast or thighs
- Boil thoroughly and shred into small pieces
- Combine with plain, cooked white rice in a 1:2 ratio (chicken to rice)
- Serve in small, measured amounts
2. Lean Ground Turkey and White Rice
- A good alternative for poultry-sensitive dogs
- Ensure it’s plain (no seasoning or oils) and fully cooked
- Drain any residual fat
3. Extra-Lean Ground Beef and Rice
- Only use 90% lean ground beef or leaner
- Cook thoroughly and drain fat completely
- Not suitable for dogs with pancreatitis or fat sensitivity
For mild cases, these home-prepared options are usually sufficient. However, for dogs with chronic GI conditions or more complex presentations, we may recommend a prescription veterinary diet, such as:
- Hill’s Prescription Diet i/d®
- Royal Canin Gastrointestinal Low Fat®
- Purina Pro Plan Veterinary Diets EN®
These diets are designed to reduce intestinal inflammation, support gut flora, and provide optimal nutrient absorption during recovery. If your dog is treated here at our clinic, we may start them on one of these diets immediately and send you home with continued feeding instructions.
Step 3: Feeding Frequency and Quantity
To avoid overwhelming the GI system, it’s best to feed small, frequent meals throughout the day.
Recommended feeding schedule:
- 4 to 6 small meals per day
- Start with approximately 1 tablespoon per 10 pounds of body weight per meal
- Gradually increase as stools normalize and tolerance improves
Once stools begin to return to normal (typically within 2–3 days), transition back to regular food over 5–7 days to prevent relapse:
- Days 1–2: 75% bland diet / 25% regular food
- Days 3–4: 50/50 blend
- Days 5–6: 25% bland / 75% regular
- Day 7: Return to 100% regular food
Transitioning too quickly is one of the most common causes of repeat episodes. If your dog is on a prescription diet, consult your veterinarian before making any changes.
Step 4: Keep a Close Eye on Hydration
Dehydration is a critical concern, especially in small dogs, puppies, and seniors. Diarrhea causes rapid loss of fluids and electrolytes.
Signs of dehydration include:
- Dry or tacky gums
- Sunken eyes
- Reduced skin elasticity
- Lethargy or weakness
- Decreased urination
At home, you can support hydration by:
- Offering water with ice chips
- Adding unflavored Pedialyte (only under veterinary guidance)
- Flavoring water with a small amount of low-sodium chicken broth
For dogs who are already dehydrated or unable to drink, we may administer subcutaneous or intravenous fluids during your ER visit to stabilize them and restore proper hydration.
Step 5: Add a Veterinary Probiotic
Diarrhea disrupts the balance of bacteria in the gut, which can slow down recovery and increase the risk of recurrence. That’s why we often recommend starting a dog-safe probiotic alongside dietary changes.
Our most trusted probiotic formulations include:
- Purina FortiFlora®
- Nutramax Proviable®
- Visbiome Vet®
These products contain beneficial strains that help reestablish a healthy microbiome, improve stool quality, and reduce inflammation in the intestines. Probiotics can be continued even after recovery to support long-term gut health.
Foods to Avoid During Recovery
While your dog’s GI tract is healing, it’s essential to avoid:
- High-fat or greasy foods (e.g., bacon, sausage, hamburger)
- Dairy products, even if tolerated in the past
- Human food seasoned with garlic, onion, or spices
- Store-bought treats or chews
- Raw diets or unregulated supplements
- High-fiber ingredients like canned pumpkin (which can worsen acute diarrhea early on)
Until your dog is back to normal, stick with bland, simple foods and avoid introducing anything new.
When to Bring Your Dog to Our Emergency Center
As a specialty and emergency facility, we often see dogs that initially tried home care but worsened. While some mild cases of diarrhea can be managed at home, please come in immediately if your dog shows any of the following:
- Diarrhea lasting longer than 24–36 hours
- Vomiting in combination with diarrhea
- Blood in the stool (bright red or black and tarry)
- Collapse, shaking, or signs of shock
- Refusal to eat or drink for more than 12 hours
- Known ingestion of a toxin, foreign object, or human medication
- Preexisting medical conditions like diabetes, kidney disease, or immunosuppression
Our team can perform diagnostic testing, including bloodwork, fecal exams, radiographs, ultrasound, and endoscopy to identify the underlying cause and initiate immediate treatment.
If Your Dog Has Chronic or Recurrent Diarrhea
When diarrhea becomes a frequent problem, it’s time to investigate more deeply. At Gilbert Queen Creek Emergency Veterinarian and Specialty Center, our internal medicine specialists and advanced diagnostics can help diagnose and manage chronic GI diseases, such as:
- Inflammatory Bowel Disease (IBD)
- Food allergies or intolerances
- Pancreatitis or EPI (Exocrine Pancreatic Insufficiency)
- Liver or kidney disorders
- Addison’s Disease
- Stress-related colitis
Through long-term dietary plans, medication, probiotics, and regular monitoring, we can help your dog find lasting relief.
