2025 Vet Guide: Why Isn’t My Dog Eating? Causes & Solutions 🐶🍽️

By Dr. Duncan Houston BVSc

When a dog refuses food, it can be worrisome. Not eating (anorexia) or reduced appetite (hyporexia) can signal anything from mild stress or picky habits to serious health issues. This guide explores the causes, how to address them, when it’s urgent, and how Ask A Vet, Woopf, and Purrz tools can help your pup regain their appetite. 🍲

🔍 1. Defining the Problem

Anorexia: complete refusal to eat. Hyporexia: only eating small amounts.
Pseudo-anorexia: wants to eat but can’t due to pain or physical inability.

🩺 2. Medical Causes

• Gastrointestinal disease: parvovirus, upset stomach, obstructions, IBD, ulcers.
• Organ dysfunction: kidney/liver disease, pancreatitis, diabetic ketoacidosis.
• Dental issues: pain from periodontal disease, fractured teeth.
• Cancer: Tumors in the mouth or GI tract cause appetite loss.
• Pain/discomfort: arthritis, hip dysplasia, making eating difficult.
• Medication side effects or toxins.

😟 3. Behavioral & Environmental Factors

• Stress or anxiety due to new environments, people, pets, or travel.
• Picky eating from boredom, spoiled habits, or food fatigue.
• Changes in feeding routine: new bowl location or schedule.
• Aging and cognitive decline reduce appetite in seniors.

⚠️ 4. When to See the Vet

Signs that need prompt attention include:

• No eating for >2 days in adults; even shorter in puppies or diabetics.
• Accompanying symptoms: vomiting, diarrhea, lethargy, fever, dehydration.
• Painful behaviors, difficulty eating, and weight loss.
• Appetite loss in diabetic dogs—urgent risk of insulin imbalance.

🔬 5. Veterinary Diagnostics

• Physical exam, dental check, abdominal palpation
• Bloodwork, chemistry, urinalysis, and diabetic panels.
• Imaging: X-rays/ultrasound for obstructions, organ issues.
• GI testing: fecal exams, parvo, IBD; biopsies if needed.

🍛 6. At‑Home Management

• Entice with warmed food, broth, boiled chicken & rice.
• Offer high-value treats or hand-feed in a calm space.
• Switch bowls to a raised or non-slip version if needed.
• Slowly transition foods over several days to avoid GI upset.

💊 7. Veterinary‑Prescribed Appetite Aids

• Mirtazapine or Entyce® stimulates hunger.
• Anti-nausea meds (Cerenia®, ondansetron) help dogs who feel queasy.
• Acupuncture may reduce nausea and discomfort.

🛠️ 8. Tools & Support Systems

• Ask A Vet: Remote triage, prescription guidance, and on‑call vet support.
• Woopf: Meal reminders, medication alerts, and hydration tracking.
• Purrz: Appetite logging, symptom trends, and behavior triggers.
