It can be alarming when your pup isn’t as hungry as usual. Stress or minor illness often causes a short dip, but sometimes it’s more serious, so watch closely.

Symptoms of loss of appetite in dogs

Signs your dog may not be eating enough:

  • Not eating as much as normal
  • Being unable to finish a meal
  • Not eating at all
  • Not interested in treats
  • Weight loss
  • Lethargy or decreased activity
  • Depressed or unusual behavior

When to see your vet

Call your vet if loss of appetite lasts more than a day or two, or comes with vomiting, diarrhea, lethargy, weight loss or behavior changes. Have puppies, seniors and dogs with health conditions checked sooner. This guide is general information, not a diagnosis.

Top reasons your dog won’t eat

The most common culprits, and what to do about each.

01

Illness

Like a cold for us, illness can dull appetite. Watch for:

  • Change in behavior
  • Stiffness or trouble walking or climbing steps
  • Excessive sleeping
  • Coughing, sneezing or difficulty breathing
  • Diarrhea or nausea
  • Red or cloudy eyes

See any of these? Take your dog to the vet.

02

Medication

New prescriptions, including antibiotics, can upset the stomach. Warming the food or hand feeding may help.

No better in a day or two? Contact your vet.

03

Dental problems

Sore teeth or gums make chewing hurt, even when you can’t spot a problem.

No better in a day or two? Have your vet check teeth and gums.

04

Recent vaccination

A dip in appetite after vaccines isn’t uncommon, and is usually minor and short-lived.

Lasts over a day or two, or other symptoms? Call your vet.

05

Travel and new places

Moves, trips and long car rides can stress dogs or cause motion sickness. Appetite usually returns soon.

Ask your vet before giving any motion-sickness medication.

06

Absence of owner

Some dogs only skip meals when you’re gone. If they eat normally when you’re home, it’s usually fine.

Going days without eating? Contact your vet.

07

Behavior

Some dogs are fussy or hold out for table scraps. Unfamiliar dogs or people can put them off food.

Rule out other causes first.

08

Time of day

Many dogs prefer certain mealtimes. Try different times and see what works.

09

Food preferences

New food, or a changed recipe? Check the expiration date, and switch gradually over one to two weeks.

10

Old age

Appetite often dips as dogs slow down and smell and taste dull. Once your vet rules out other causes, more walks can help.

What to do when your dog is not eating

A brief dip with no other signs is probably nothing to worry about. If it lasts more than a day or two, or other symptoms appear, call your vet.

For more help with fussy dogs, see our guide on how to get your dog to eat.

If your dog is sick

Follow your vet’s feeding plan. With your vet’s okay, these can make a meal more appealing:

  • Warm the food slightly before serving
  • Try hand feeding
  • Add warm water to dry food to soften it
  • Add a little plain, low-sodium broth with no onion or garlic
  • Offer dry food if your dog usually eats wet, or wet if they usually eat dry

If it’s a behavior issue

Once sickness is ruled out, these habits help:

  • Feed at the same times every day; two meals a day is a good routine
  • Cut back on people food and treats
  • Get some exercise in to work up an appetite
  • Feed alone, away from other dogs and noise
  • Make mealtime a training session and reward a trick
  • Try a different food your dog finds tastier
