At Johnson Ranch Animal Clinic, we know how stressful it is when your dog has diarrhea. Whether it’s a sudden upset or something that’s been building for a few days, it can leave you worried, cleaning up messes, and unsure what to do next. One of the most common questions we get is:
“What should I feed my dog when they have diarrhea?”
We’re here to help answer that question, clearly, compassionately, and thoroughly. Our team believes that pet care is a partnership, and we want you to feel empowered with the right information to care for your dog at home and know when to seek professional help.
Why Do Dogs Get Diarrhea?
Diarrhea is one of the most common concerns we see at Johnson Ranch. While it can be caused by something as simple as an upset stomach, it can also signal an underlying issue. Here are some of the top causes we see:
- Eating something unusual: trash, table scraps, spoiled food, bones, or other non-food items
- Sudden food changes: switching kibble or protein sources too quickly
- Stress or anxiety: travel, boarding, loud noises, or household changes
- Parasites: like giardia, hookworms, coccidia, or roundworms
- Bacterial or viral infections: including parvovirus, distemper, or salmonella
- Food allergies or sensitivities: sometimes to common proteins or grains
- Medication side effects: particularly antibiotics, NSAIDs, or supplements
- Underlying health issues: like pancreatitis, inflammatory bowel disease (IBD), Addison’s disease, or exocrine pancreatic insufficiency (EPI)
- Foreign body ingestion or toxin exposure
Mild diarrhea from diet changes or stress might pass in a day or two. But more serious or ongoing diarrhea should always be evaluated by a vet, especially if other symptoms appear.
Step 1: Should You Withhold Food?
If your dog is otherwise acting normally – alert, hydrated, and not vomiting, it’s sometimes helpful to withhold food for up to 12 hours. This brief fasting period allows the digestive system to rest and recover.
However, fasting is not recommended if your dog is:
- A puppy under six months
- A small breed (prone to low blood sugar)
- A senior dog or one with chronic conditions (like diabetes or kidney disease)
If you’re unsure whether fasting is appropriate for your dog, call us at Johnson Ranch. Our team is happy to walk you through the best plan for your pet’s age, breed, and medical history.
Even if you’re withholding food, always provide fresh, clean water to help prevent dehydration. You can also offer small ice cubes if your dog is hesitant to drink.
Step 2: Switch to a Bland Diet
After a rest period, or if your dog shouldn’t fast, it’s time to introduce a bland, easy-to-digest diet. These foods are gentle on the stomach and can help firm up stools while giving your pet the nutrients they need.
The Goals of a Bland Diet:
- Soothe the digestive tract
- Improve stool consistency
- Restore energy and hydration
- Support gut healing
Here are our most trusted bland diet options at Johnson Ranch:
1. Boiled Chicken and White Rice
- Use skinless, boneless chicken breast or thighs
- Boil until fully cooked, then shred
- Combine with plain white rice (not brown rice), in a 1:2 ratio of chicken to rice
- Avoid seasonings, oils, and broth
2. Boiled Ground Turkey and Rice
- An excellent alternative for dogs with chicken sensitivities
- Use lean ground turkey, cook thoroughly, and drain off any fat
3. Boiled Lean Ground Beef and Rice
- Choose extra-lean ground beef (at least 90%)
- Drain fat completely after cooking
- Works well for dogs who don’t tolerate poultry
4. Prescription Gastrointestinal Diets
If your dog’s diarrhea is more serious, persistent, or related to a chronic condition, we may recommend a prescription diet such as:
- Hill’s Prescription Diet i/d®
- Royal Canin Gastrointestinal Low Fat®
- Purina Pro Plan EN®
These formulas are designed to be highly digestible and support the gastrointestinal system. If needed, we can help you select the best one for your dog and provide samples or starter packs.
Step 3: How Much to Feed and When
When feeding your dog during recovery, small and frequent is key:
- Start with 4 to 6 small meals per day
- Offer 1 tablespoon per 10 pounds of body weight per meal to start
- Monitor stool quality and overall behavior closely
As your dog begins to improve, you’ll want to gradually transition back to their regular food over 5–7 days:
- Days 1–2: 75% bland diet / 25% regular food
- Days 3–4: 50% bland / 50% regular
- Days 5–6: 25% bland / 75% regular
- Day 7: Return to 100% regular food, assuming stools are firm
This slow transition helps avoid another episode of GI upset.
Step 4: Hydration Is Essential
Diarrhea leads to significant fluid and electrolyte loss. Dehydration can happen quickly, especially in smaller dogs, puppies, and seniors.
Signs of Dehydration:
- Dry, sticky gums
- Sunken eyes
- Lethargy or weakness
- Skin that doesn’t spring back when gently pinched
Make sure your dog has access to clean, cool water at all times. If needed, we may recommend:
- Unflavored Pedialyte (diluted, and with our guidance)
- Subcutaneous fluids, which we can provide in-clinic to support rehydration
- IV fluids for dogs who are severely dehydrated or unable to drink
Step 5: Add Probiotics for Gut Health
Diarrhea often disrupts your dog’s gut bacteria. Adding a dog-safe probiotic helps restore balance and supports faster recovery.
At Johnson Ranch, we recommend trusted, vet-approved options such as:
- Purina FortiFlora®
- Proviable® DC or KP
- Visbiome Vet®
We can help you choose the right probiotic and dosage based on your dog’s age, size, and condition.
Foods to Avoid While Your Dog Is Recovering
During recovery, certain foods can make symptoms worse or delay healing. Avoid:
- Fatty meats or scraps
- Cheese or other dairy products
- Seasoned or spicy foods
- Store-bought treats (especially with additives or dyes)
- High-fiber ingredients (like pumpkin) in early recovery stages
- Raw food diets or bones
Stick to plain, gentle ingredients until your vet gives the green light to reintroduce other foods.
When to Call Johnson Ranch Animal Clinic
Some cases of diarrhea can be treated at home but others need veterinary care. Call us right away if your dog experiences:
- Diarrhea lasting longer than 24–48 hours
- Vomiting along with diarrhea
- Blood in the stool (bright red or black/tarry)
- Lethargy, shaking, or collapsing

We’re here to help. Our clinic can run diagnostic tests like fecal exams, bloodwork, imaging, or dietary trials to determine the cause of diarrhea and get your dog back on track quickly.
What If It Keeps Happening?
If your dog has frequent or long-lasting diarrhea, it could signal an underlying condition that requires ongoing management. Common culprits include:
- Inflammatory Bowel Disease (IBD)
- Pancreatitis
- Addison’s disease
- Exocrine Pancreatic Insufficiency (EPI)
- Food allergies or intolerances
- Liver or kidney disease
