How Does a Dog Act When They Are Poisoned: Recognizing the Warning Signs

Have you ever had that sinking feeling when your furry friend starts acting weird out of nowhere? As dog parents, we’re always on high alert when our pups show unusual behavior. One of the scariest scenarios is potential poisoning. I’ve researched extensively on this topic, and today I’m sharing what you need to know about how dogs act when they’ve been poisoned.

The Telltale Signs Your Dog Has Been Poisoned

Dogs are naturally curious creatures who explore the world with their mouths. Unfortunately this curiosity can sometimes lead them into trouble. When a dog has consumed something toxic, their behavior can change dramatically and suddenly. Here are the most common symptoms you might notice

Physical Symptoms

• Vomiting – Often one of the first signs
• Diarrhea – May contain blood or appear discolored
• Pale or yellowish gums – Indicates potential organ problems
• Excessive thirst or urination
• Drooling – Especially if the toxin caused oral irritation
• Bloody urine
• Nosebleeds
• Excessive bruising or bleeding

Behavioral Symptoms

• Lethargy or weakness – Your normally active dog seems tired or uninterested
• Unsteady gait – Stumbling or appearing drunk
• Agitation – Unusual restlessness or anxiety
• Seizures, tremors, or convulsions
• Collapse – In severe cases
• Abnormal heart rhythm
• Inability to urinate

Dr. Jerry Klein, Chief Veterinarian for the American Kennel Club, explains that depending on the toxin, “dogs may show a reaction within minutes.” However, with some poisons like rodenticides, “it can take several days for symptoms to appear.”

Common Household Poisons That Affect Dogs

Most poisoning cases happen right at home with items we might not even consider dangerous. According to veterinarians, these are the most common culprits:

Medications

• Over-the-counter pain relievers (Tylenol, ibuprofen, Advil, Aleve)
• Prescription medications
• Antidepressants
• Birth control pills
• Heart and blood pressure medications
• Cold medicine
• Herbal supplements and vitamins

Remember that “childproof containers” aren’t “dog-proof containers”!

Foods Toxic to Dogs

• Chocolate
• Grapes and raisins
• Onions and garlic
• Xylitol (found in sugar-free gum, some peanut butters, toothpastes, and candies)
• Marijuana and edibles containing THC

Household Products

• Cleaning products (bleach, window cleaner, bathroom cleaners)
• Antifreeze
• Paint thinner
• Pool chemicals
• Dishwashing detergent
• Fabric softener sheets

Outdoor Hazards

• Rodenticides (rat poison)
• Insecticides
• Fertilizers
• Weed killers
• Toxic plants (azaleas, rhododendrons, tulips, daffodils, sago palms)
• Cocoa mulch

Timing Matters: Quick vs. Delayed Symptoms

One tricky aspect of poisoning is that symptoms don’t always appear immediately. The timing of symptoms depends on:

1. Type of toxin – Some poisons act immediately, others take days
2. Amount consumed – Larger quantities generally cause faster reactions
3. Your dog’s size – Smaller dogs show symptoms more quickly
4. Your dog’s overall health – Dogs with existing conditions may react differently

What to Do If You Suspect Poisoning

If you think your dog has been poisoned, every minute counts! Here’s what to do:

1. Stay calm – Your dog needs you thinking clearly
2. Remove your dog from the source of poison
3. DO NOT try to induce vomiting unless specifically instructed by a vet (some substances cause more damage coming back up)
4. Contact your veterinarian immediately or an emergency vet hospital
5. If possible, bring the packaging or a sample of the suspected poison
6. Collect samples of vomit or diarrhea if present

Important Emergency Numbers to Save:

• Your regular vet’s phone number
• The nearest 24-hour emergency vet clinic
• Pet Poison Helpline: 855-764-7661 (they charge $59 per call)
• ASPCA Animal Poison Control Center: 888-426-4435 (available 24/7, consultation fee applies)
• AKC Vetline: A 24/7 service with access to trained pet care professionals ($99 for your dog’s lifetime)

How Vets Treat Poisoning in Dogs

Treatment depends on the specific poison and how quickly your dog gets to the vet. Common approaches include:

• Activated charcoal to absorb poison from the stomach
• Inducing vomiting (only when safe and appropriate)
• Gastric lavage (stomach pumping)
• IV fluids to help flush toxins
• Specific antidotes for certain poisons (like rodenticides or antifreeze)
• Medication to manage symptoms
• Hospitalization for monitoring and supportive care

Long-Term Effects of Poisoning

Even after initial treatment, some toxins can cause lasting damage:

• Anemia (when toxins damage red blood cells)
• Cardiovascular issues and irregular heartbeat
• Liver damage
• Kidney failure
• Neurological problems

Prevention: The Best Approach

We all know that preventing poisoning is way better than treating it. Here are some practical tips to keep your curious pup safe:

Inside Your Home

• Store medications (both human and pet) in sealed containers in high cabinets
• Keep food items like chocolate, grapes, and xylitol products out of reach
• Store cleaning products in secure locations
• Teach your dog the “leave it” command for emergencies
• Don’t take medications when your dog is nearby
• Be extra careful with marijuana products and edibles

In Your Yard

• Research plants before adding them to your garden
• Avoid cocoa mulch
• Store fertilizers, weed killers, and pesticides securely
• Wait until surfaces are completely dry after cleaning before allowing dogs access
• Keep garbage securely contained

Case Study: My Friend’s Experience

My friend Sarah had a terrifying experience when her Lab mix, Cooper, got into some rat poison in the garage. At first, she just noticed he seemed a bit tired and wasn’t eating well. By day two, Cooper started having bloody nose bleeds and was extremely weak.

When she rushed him to the emergency vet, blood tests showed his clotting ability was severely compromised. Thankfully, the vet was able to treat him with vitamin K and supportive care. Cooper made a full recovery, but Sarah learned a hard lesson about keeping potentially toxic substances completely out of reach.

The Rising Trend of Marijuana Poisoning

With marijuana legalization spreading across many states, veterinarians are seeing an alarming increase in cannabis toxicity cases in dogs. Dogs who ingest marijuana products may show:

• Lethargy
• Incoordination
• Dilated pupils
• Urinary incontinence
• Slow heart rate
• In severe cases, seizures

THC edibles are particularly dangerous since they’re often in forms (like brownies or cookies) that are already appealing to dogs. The combination of chocolate and THC can be especially dangerous.

Essential Oil Dangers

Another worrying trend is poisoning from essential oils. Many essential oils that we use for aromatherapy or cleaning can be toxic to dogs, especially:

• Tea tree oil
• Pennyroyal
• Wintergreen
• Pine oils
• Citrus oils

Dogs exposed to toxic essential oils might drool excessively, vomit, have tremors, or experience breathing difficulties.

Final Thoughts

When it comes to potential poisoning, it’s always better to be safe than sorry. If you notice unusual symptoms in your dog, don’t waste time wondering if it’s serious—contact your vet immediately. The faster your dog receives treatment, the better their chances of a full recovery.

I hope you never need this information, but keeping it in mind could literally save your dog’s life one day. Have you ever had a scary experience with your dog getting into something toxic? Share your story in the comments to help other pet parents stay vigilant!
