My Dog Ate Something Toxic: The First Five Minutes

The moment to act is the moment you find the wrapper, not the moment your dog looks ill. With the worst poisons, those are days apart.

This is the general playbook for the moment you realise your dog may have eaten something it should not have, whatever that something turns out to be.

Everything else in this section deals with a specific substance. This page is about the first ten minutes, before you know which one you are dealing with, and it rests on a single principle that runs against instinct.

Act on the suspicion, not the symptoms.

Why waiting is the trap

It is completely reasonable to want to see whether your dog actually becomes unwell before troubling anyone. With poisons it is the wrong instinct, because many of the worst ones do nothing visible for hours or days while damage accumulates underneath.

Xylitol crashes blood sugar in fifteen minutes but the liver damage comes later. Anticoagulant rat poison causes no signs for several days. Cholecalciferol takes out the kidneys over two or three. Paracetamol, grapes and onions all work on a delay.

By the time those dogs look ill, the treatable window has usually closed. So treat vomiting, wobbliness or drooling as confirmation that an exposure happened, not as your signal to act. The signal to act is the chewed wrapper, the missing pills, the empty bait tray, and a dog that appears completely fine.

That moment, with no symptoms at all, is the single highest-leverage point in the whole business.

What to do

1. Get your dog away from the substance. If there is still some in its mouth, tempt it to drop it with a treat rather than putting your fingers in. Wipe any residue off the fur and paws so it cannot lick more off itself.
2. Ring your vet or a poison line straight away. In the UK, the Animal PoisonLine. In the US, the ASPCA Animal Poison Control Center or the Pet Poison Helpline.
3. Gather four things: what it was, roughly how much, when, and what your dog weighs. Keep the packaging, the wrapper or the remains.
4. Do what they tell you, and go in if they say so.

The rule about making your dog sick

Do not induce vomiting at home unless a vet or a poison line specifically tells you to.

There are three reasons, and they are all good ones. With corrosives like bleach and detergents, whatever burned on the way down burns again coming back up. With a dog that is drowsy, wobbly or seizing, vomit goes into the lungs. And with some substances, bringing it back up achieves nothing while delaying the treatment that would have worked.

Never use salt water to make a dog vomit. It is a folk remedy that causes salt poisoning in its own right.

Signs that confirm an exposure

• Vomiting, drooling, retching or pawing at the mouth
• Wobbliness, weakness, staggering
• Tremors, twitching or seizures
• Collapse or unresponsiveness
• Pale gums, which can mean internal bleeding, or unusually bright red gums
• Bleeding from anywhere, including hours or days later
• Drinking and urinating much more than usual, or suddenly not urinating at all
• Hiding, flatness, vocalising, or unusual aggression

Two minutes of preparation

Put your vet's number and an animal poison line into your phone now, under names you will find while panicking. The minutes people lose hunting for a number are real minutes.

And do a circuit of the house once, thinking like a dog. Human medicines, sugar-free gum, chocolate, rat bait, antifreeze in the garage, slug pellets in the shed. Most poisonings are not exotic. They happen because something ordinary was at nose height on an ordinary afternoon.
