Dog Poisoning: Symptoms, Causes, First Aid

Poisoning in dogs is always an emergency. Symptoms: vomiting, trembling, diarrhea, seizures, pale gums, all the way to unconsciousness. Call your vet or an emergency clinic right away. Do not make your dog vomit. Give activated charcoal only if a vet or professional tells you to, and take the poison, packaging, vomit, or stool as a sample.

First aid in an emergency

What are charcoal tablets?

Charcoal tablets are made of medicinal charcoal, which is obtained from plant parts such as wood, peat, or coconut shells. Activated charcoal is highly porous like a sponge: the surface area of four grams of activated charcoal is about the size of a soccer field.

Because of this structure, activated charcoal binds toxins in the gastrointestinal tract and renders them harmless to the body. The bound substances are excreted in the stool (which turns black in the process: that's normal).

The faster activated charcoal contacts some poisons, the more useful it can be. It is not right for every toxin and never replaces veterinary care. Give it only if your vet or an emergency clinic tells you to.

Tip

Ask your vet ahead of time whether activated charcoal belongs in your dog first-aid kit and which emergency number to call. Keep your dog warm and pad the surroundings so it cannot hurt itself during seizures.

What the vet should know

Help the vet by giving them this information:

InformationWhy it matters
Which poison was ingested?Targeted treatment
Sample available? (incl. packaging)Identifying the toxin
When was the poison ingested?Time window for treatment
Which symptoms are present?Assessing severity
How much was ingested?Dose-dependent treatment

If possible, bring vomit or stool along as a sample.

Frequently Asked Questions

How do I recognize poisoning in my dog?

There are many different symptoms: vomiting, trembling, diarrhea, seizures, pale gums, all the way to unconsciousness. The more symptoms that appear at the same time, the more likely poisoning is.

How do I help my poisoned dog?

Call your vet or an emergency clinic right away. Have the poison, amount, timing, symptoms, and your dog's weight ready. Give activated charcoal only if they tell you to. Take the poison, packaging, vomit, or stool along as a sample.

How do I keep my dog from getting poisoned?

Keep all sources of danger out of your dog's reach. On walks, watch what your dog picks up. Train the "drop it" command.

Is poisoning in dogs fatal?

That depends on the poison, the dose, and how quickly treatment happens. Not every poisoning ends fatally, but it is always an emergency. The faster the vet treats it, the better the chances.

Should I make my dog vomit?

No! Forced vomiting can make things worse and waste valuable time. Leave that to the vet.
