Food refusal is a symptom, not a personality diagnosis.

Separate interest in food from the ability to chew and swallow it.

Do not keep changing foods for days while other concerning signs are developing.

What this can look like, and what to do next.

Break 'not eating' into observable steps

Does your dog approach the food, sniff, lick, take a piece, chew, swallow, and return? A dog who wants food but drops it has a different problem from one who turns away, lip-licks, drools, or appears nauseated.

Record the last normal meal

Write the time and amount of the last normal meal, every food or treat offered since, water intake, vomiting, stool, urination, medication, and behavior. Include table food and hand-feeding so the clinic sees the full intake.

Look for pain and access problems

Dental pain, neck or back pain, difficulty standing at the bowl, sliding feet, or trouble lowering the head can change eating. A stable mat, reachable bowl, and quiet space may help, but persistent appetite change still needs veterinary guidance.

Medication timing can matter

Some medications affect appetite or cause gastrointestinal signs; others should not be stopped abruptly. Call the prescribing clinic with the exact drug, dose, last administration, and current symptoms rather than changing the plan yourself.

Avoid the endless food carousel

Repeatedly offering rich or unfamiliar food can create diarrhea, obscure intake, or complicate a prescribed diet. Ask the clinic what is safe to offer and whether an exam is needed before trying appetite stimulants, antacids, or supplements.

Make the plan measurable

Ask what the veterinarian suspects, what must be ruled out, what minimum intake is expected, how hydration will be assessed, and when lack of improvement becomes urgent. Weighing food before and after can make follow-up more precise.

When to call sooner

  • Your dog cannot swallow, repeatedly retches, has a swollen abdomen, or struggles to breathe
  • Repeated vomiting, black or bloody stool, marked weakness, collapse, or severe pain
  • A dog with diabetes or another time-sensitive disease misses food or medication
  • Appetite loss persists, especially with weight loss, thirst change, dental signs, or new medication

Keep going.
