Common Causes of Digestive Problems in Dogs

Dietary Indiscretion

Dogs often eat things they should not, including garbage, spoiled food, table scraps, plastic, toys, or toxic substances. This is one of the most common reasons for stomach upset in dogs.

Sudden food changes can also irritate the digestive system and cause vomiting or diarrhea.

Food Allergies and Sensitivities

Some dogs develop digestive issues after eating certain proteins, grains, or ingredients. Food intolerance may cause:

• Chronic diarrhea
• Vomiting
• Gas
• Itchy skin
• Ear infections
• Loose stool

A hypoallergenic or limited-ingredient diet may help dogs with food sensitivities.

Stress and Anxiety

Stress diarrhea is very common in dogs. Boarding, traveling, loud noises, separation anxiety, or routine changes may trigger digestive upset.

Dogs experiencing stress-related digestive problems often develop loose stool, gas, or appetite loss.

Gastroenteritis in Dogs

Gastroenteritis refers to inflammation of the stomach and intestines. It commonly causes vomiting, diarrhea, abdominal pain, and dehydration.

Possible causes include:

• Viral infections
• Bacterial infections
• Parasites
• Toxins
• Spoiled food
• Sudden diet changes

Mild cases may improve with supportive care, while severe cases require veterinary treatment.

Constipation in Dogs

Constipation occurs when stool becomes difficult to pass. Dogs may strain frequently or produce hard, dry feces.

Common causes include:

• Lack of fiber
• Dehydration
• Bone consumption
• Poor diet
• Intestinal obstruction
• Lack of exercise

Adding fiber, increasing hydration, and improving diet quality often helps mild constipation.

Pancreatitis in Dogs

Pancreatitis is inflammation of the pancreas and can become very serious. Fatty foods and table scraps are common triggers.

Symptoms include:

• Vomiting
• Severe abdominal pain
• Diarrhea
• Loss of appetite
• Weakness

Many dogs with pancreatitis require hospitalization, IV fluids, and pain management.

Intestinal Blockages

Intestinal obstruction happens when a dog swallows something that blocks the digestive tract.

Common foreign objects include:

• Socks
• Toys
• Bones
• Corn cobs
• Plastic items
• Fabric

Signs of blockage include repeated vomiting, abdominal pain, bloating, dehydration, and inability to keep food down. Surgery is often necessary.

Gastric Dilatation and Volvulus (Bloat)

Bloat, also called GDV, is a life-threatening emergency where the stomach twists and traps gas inside.

Symptoms include:

• Swollen abdomen
• Restlessness
• Excessive drooling
• Dry heaving
• Difficulty breathing
• Collapse

Large deep-chested breeds like Great Danes and German Shepherds are at higher risk. Immediate emergency surgery is required.

Diagnosing Dog Digestive Problems

Veterinarians diagnose digestive disorders using several methods depending on symptoms and severity.

Diagnostic tests may include:

• Physical examination
• Stool testing
• Bloodwork
• X-rays
• Ultrasound
• Endoscopy
• Food elimination trials

Accurate diagnosis is important because many digestive conditions share similar symptoms.

Best Treatment for Dog Digestive Problems

Treatment depends on the underlying cause and severity of symptoms.

Common treatments include:

• Bland diet
• Fluid therapy
• Anti-nausea medication
• Probiotics
• Deworming medication
• Prescription diets
• Surgery for blockages or GDV
• Fiber supplements
• Digestive enzymes

Dogs with mild stomach upset may recover within a few days, while chronic digestive diseases require long-term management.

What to Feed a Dog With Digestive Problems

Dogs with sensitive stomachs often benefit from highly digestible foods that reduce irritation and support gut health.

Good options include:

• Boiled chicken and rice
• Pumpkin
• Low-fat diets
• Prescription gastrointestinal food
• Probiotic supplements
• Limited-ingredient diets
• Fiber-rich dog food
