2025 Vet Guide: Why Is My Dog Always Hungry? Causes & Care 🐶🍽️

By Dr. Duncan Houston BVSc

Is your dog begging for food all the time? Persistent hunger—known as polyphagia—can result from multiple factors, from normal behaviors to serious health conditions. In this guide, I’ll help you understand causes, identify red flags, and implement effective feeding, behavioral, and medical strategies. 🌟

🔍 1. What Is Polyphagia?

Polyphagia is an abnormally strong, continuous appetite that persists even after eating. It may be normal in puppies, working dogs, or those on poor-quality food, but it can also signal deeper issues.

🧠 2. Common Causes of Increased Hunger

• Dietary & behavioral: Poor-quality food, underfeeding, learned begging, boredom, anxiety.
• Parasites & malabsorption: Worms, IBD, EPI , causing nutrients to pass unabsorbed.
• Endocrine disorders: Diabetes mellitus, Cushing’s disease, hyperthyroidism, insulinoma.
• Medications: Corticosteroids (e.g., prednisone) and anticonvulsants can boost appetite.
• Growth phases: High-calorie needs in puppies, pregnant/nursing dogs, or working breeds.
• Rare neurological causes: Central nervous system disorders or brain lesions.

⚠️ 3. When It’s More Than Just Begging

If constant hunger is paired with any of the following, see your vet:

• Weight loss despite increased appetite
• Excessive thirst and urination—suspect diabetes or Cushing’s
• Vomiting, diarrhea, or signs of malnutrition
• Hair loss, pot-belly, liver issues—common in endocrinopathies

🩺 4. Veterinary Diagnostics

Your vet may recommend:

• Comprehensive history: diet, medications, behavior patterns
• Fecal exam for parasites
• Bloodwork: glucose, cortisol, thyroid, pancreatic enzymes
• Urinalysis to check for diabetes or kidney disease
• Diagnostic imaging or enzyme assays for EPI, tumors, or GI disease

🍛 5. Care & Management Strategies

5.1 Nutritional Adjustments

• Switch to balanced, high-quality diets with appropriate caloric density
• Increase fiber to boost satiety—pumpkin, green beans, or vet-formulated diet
• Divide meals into 3–4 smaller feedings daily
• Use slow feeders or puzzle toys to prolong eating time and reduce gulping

5.2 Behavioral & Lifestyle Enrichment

• Offer mental stimulation—games, training, interactive toys
• Ensure regular exercise to manage weight and appetite
• Ignore begging to avoid reinforcing the behavior

5.3 Treating Underlying Conditions

• Diabetes: Insulin therapy, dietary control
• Cushing’s: Medications like trilostane or mitotane
• EPI: Pancreatic enzymes and B₁₂ supplementation
• Parasites: Deworming and supportive nutrition
• Neurologic/endocrine disorders: Specific treatments after diagnosis
