Signs Your Dog Ate Something Bad

If only our dogs can talk.

Unfortunately, they can't tell us they don't feel good, so it's up to us, pet parents, to spot the early warning signs that our dogs ate something bad.

Recognizing these signs means the world between a mild upset stomach and a life-threatening emergency.

Mild Symptoms (Early Warning Signs)

These symptoms might indicate your dog ate something that is upsetting their stomach but may not be immediately life-threatening:

  • Vomiting or diarrhea – Common reactions to mild irritants like spoiled food.
  • Excessive drooling or foaming at the mouth – A sign of nausea or irritation from toxins.
  • Loss of appetite – Your dog may refuse food or water due to stomach discomfort.
  • Mild lethargy or restlessness – They might act “off” or seem unusually tired.
  • Gagging, coughing, or choking – could indicate a foreign object stuck in the throat.
  • Pawing at the mouth or face rubbing – A sign of discomfort, especially if they ate something spicy, toxic, or irritating.

Severe Symptoms (Signs of Poisoning or Blockage)

If your dog shows any of these severe symptoms, seek veterinary care immediately:

  • Repeated vomiting or diarrhea (with blood) – Could indicate poisoning, intestinal damage, or internal bleeding.
  • Difficulty breathing – A potential sign of an allergic reaction or airway obstruction.
  • Abdominal bloating or pain – A sign of gastrointestinal distress, blockages, or bloat.
  • Tremors, seizures, or muscle weakness – Common in cases of poisoning (e.g., chocolate, xylitol, or certain plants).
  • Sudden collapse or unconsciousness – A medical emergency requiring immediate vet attention.
  • Jaundice (yellow gums or eyes) – Can indicate liver failure, often caused by ingesting toxins like xylitol or certain mushrooms.

Behavioral Changes to Watch For

Not all symptoms are physical—changes in your dog’s behavior can also signal distress:

  • Hiding or avoiding interaction – If your normally friendly dog suddenly hides, they may feel unwell.
  • Whimpering or excessive vocalization – Dogs often cry or whine when in pain or distress.
  • Unusual aggression or confusion – Certain toxins, like antifreeze or rodent poison, can cause neurological changes.
  • Excessive licking of the lips or air – A sign of nausea or discomfort in the stomach.

Dog Ate Something Bad: How Long Before the Signs Appear

Unfortunately, there's no specific timeframe for signs appearing after your dog ingested something bad—it can be as fast as 30 minutes or as late as several days.

This largely depends on the toxin that your dog ate.

Poisonous foods like grapes or xylitol can cause rapid reactions, while blockages from swallowed objects may take 12-24 hours to show signs.

Also, it's best not to wait for any signs or symptoms before contacting your veterinarian, especially if you saw what your dog ate.

Note every detail, like what they ate, the size or amount, and when it happened—these details are very important, and we'll discuss them later.

When to Act Fast

If your dog is experiencing any severe symptoms, don’t wait—seek emergency vet care.

The faster you act, the better your dog's chances of recovery.

If they’re choking, carefully remove the object from their mouth and call your vet.

Watch out for persistent vomiting, extreme lethargy, or abdominal pain and swelling—these could indicate an intestinal blockage.


IMPORTANT:

You can save these numbers on your phone or print/write them and post them somewhere you can easily check, along with your veterinarian's contact details.

What to Do If Your Dog Ate Something Bad

Don't panic. I know that's easier said than done, but panicking will only cloud your judgment and likely cause your dog distress.

Step 1: Identify What Your Dog Ate

The first thing to do is to identify what your dog ate.

If you witnessed it yourself, that's good. If not, there should be ways you can try to identify whatever your pup ate.

Check your home for missing food, packaging, chewed-up, or misplaced objects.

They're no smooth criminals, our dogs. They will likely leave a trail wherever they put their paws on.

If possible, try to determine how much they consumed.

If it's a plastic container, how much of the container is missing?

If it's chewed-up packaging, are all the contents missing or just some?

These will be important for the next step.

Step 2: Call Your Vet or Pet Poison Helpline

Immediately contact your dog's veterinarian or these helplines:

Provide your dog's details, such as breed, weight, age, what it ate and how much, and the signs and symptoms you're seeing.

Remember, for certain toxins like xylitol, you will only have minutes to spare before your dog becomes seriously ill—so act fast and call for help!

Step 3: To Induce Vomiting or Not?

In some cases, the veterinarian or even the poison hotline rescuers will instruct you to induce your dog to vomit.

If you have it on hand, they will likely ask you to give your dog a teaspoon of 3% hydrogen peroxide for every 20 lbs. of body weight.

Read the linked article below for more details on how to do this safely.

However, this is NOT always the case. Some ingested toxins, such as sharp objects or acid cleaners, will do more damage when vomited.

Step 4: Vet Treatment

Once your dog has received first aid, you'll still need to rush him to the vet for further assessment.

If you weren't successful in getting your dog to throw up at home, the vet will do it at the clinic if it is safe and necessary.

They will likely inject your dog with Apomorphine to induce vomiting.

In some cases, activated charcoal will also be administered to help absorb the toxins and prevent them from being absorbed by the body.

However, do not do it yourself at home—activated charcoal can be toxic to dogs when not given properly.

Your dog will also receive IV fluids to prevent dehydration.

If an object is stuck somewhere in the stomach, an endoscopy and/or surgery will likely be done.

Step 5: Monitor for Worsening Symptoms

At this point, your dog should have been attended to by the experts already.

Follow the treatments prescribed by the veterinarian strictly and bring your dog for scheduled follow-up check-ups.

Most importantly, monitor your dog for worsening symptoms, if any.

Watch out for persistent vomiting, lethargy, or difficulty breathing.

Return to the vet hospital immediately if you feel the treatment is not working and your dog is getting worse.
