Dog first aid: what to do before you reach the vet
How to recognise an emergency in your dog, keep yourself and your dog safe, what to keep in a basic first-aid kit, and when to call the vet. First aid only buys time until your dog can be seen; it is never a replacement for veterinary treatment.

The short answer
If your dog is injured or suddenly unwell, stay calm, keep yourself safe and phone your vet straight away, or your vet's out-of-hours service if the practice is closed. Ring before you set off so the team can prepare. Breathing trouble, collapse, seizures, suspected poisoning, heatstroke, a swollen tummy with retching, heavy bleeding and road accidents are all emergencies. Never give human medicines, and don't try to treat serious problems at home.
Key considerations
- 01Save your vet's number and their out-of-hours number in your phone now, before you need them.
- 02Always phone ahead so the vet team knows you are coming and can tell you what to do on the way.
- 03A frightened or hurt dog may bite, even a gentle one. Protect yourself before you help.
- 04Never give your dog human painkillers or other human medicines. Some are poisonous to dogs.
Accidents and sudden illness happen, often at night or at weekends. Knowing what counts as an emergency, and what to do in the first few minutes, can make a real difference. First aid is about keeping your dog as safe and comfortable as possible until a vet can take over. It is not a replacement for veterinary treatment.
Be ready before anything happens
- Save the numbers. Put your vet practice's number and their out-of-hours service in your phone. Many practices use a separate out-of-hours clinic, so check where it is and how long it takes to get there.
- Know how you would travel. Think about how you would get your dog to the vet at night, and how you would carry them if they couldn't walk.
- Keep your dog's details handy. Note any medicines, conditions and their approximate weight.
- Consider insurance or savings. Emergency care can be expensive, and it helps to know in advance how you would pay.
Emergencies: call a vet straight away
Phone your vet, or the out-of-hours service, immediately if your dog:
- is struggling to breathe, is breathing noisily, or has pale, blue or grey gums
- has collapsed, can't stand or is very weak
- is having a seizure (fit), or has had more than one
- may have eaten something poisonous, such as chocolate, grapes, raisins, xylitol (found in some sugar-free foods), rat or slug bait, antifreeze or human medicines, even if they seem fine
- is panting heavily, drooling, wobbly or collapsing in warm weather, which can be heatstroke
- has a swollen, tight tummy and is retching without bringing anything up, which can be a sign of bloat, a life-threatening problem especially in large, deep-chested dogs
- is bleeding heavily or the bleeding won't stop
- has been hit by a vehicle, even if they seem unhurt
- has an eye injury, or an eye that looks suddenly cloudy, bulging or painful
- is straining to wee and producing little or nothing
- has repeated vomiting or diarrhoea, especially with blood, or seems in severe pain
If you are unsure whether it is an emergency, phone and ask. Vets would much rather hear from you early.
Keep yourself safe
A dog in pain or shock may bite, even a dog that has never bitten before. Approach slowly and speak calmly. Keep your face away from your dog's mouth. If your dog has been hit by a car, check that traffic is safe before you go to them.
A properly fitting basket muzzle can protect you while you move a dog in pain, but don't muzzle a dog that is struggling to breathe, vomiting or overheating. If you are not sure, ask the vet on the phone.
What to do while you get help
Bleeding
Press firmly on the wound with a clean pad or cloth and keep the pressure on while someone drives you to the vet. If blood soaks through, add more padding on top rather than removing the first layer.
Suspected poisoning
Phone your vet immediately. Tell them what your dog ate, how much and when, and take the packet or a photo of it with you. Don't try to make your dog sick unless a vet tells you to, as this can cause more harm. Animal PoisonLine, a 24-hour veterinary poisons service, also takes calls from owners, but your vet is the first call.
Heatstroke
Heatstroke can kill. Move your dog somewhere cool and shaded, start cooling them straight away by soaking them with tap water while keeping air moving over them, and phone your vet while you do it. Don't let them breathe in water. Keep cooling on the way to the vet if you can, for example with the car's air conditioning on.
Seizures
Keep your dog away from stairs, water and furniture they could fall from, and keep your hands away from their mouth. Dim the lights and keep the room quiet. Time the seizure and phone your vet. A seizure lasting more than a few minutes, or one fit following another, needs urgent care.
Moving an injured dog
Keep your dog as still as possible. Small dogs can be carried in a box or carrier. For a larger dog, use a blanket or a board as a stretcher, with one person at each end, keeping the back and neck as level as you can.
Never give human medicines
Human painkillers, including ibuprofen and paracetamol, and many other human medicines can poison dogs. Never give your dog any medicine that hasn't been prescribed for them by a vet, even if your dog seems to be in pain. Your vet can give pain relief that is safe for dogs.
A basic dog first-aid kit
Keep a kit at home and a smaller one in the car:
- your vet's number and the out-of-hours number, written down
- clean towels and a blanket
- non-stick wound dressings, cotton bandage and self-adhesive bandage
- sterile saline for rinsing dirt from wounds or eyes
- blunt-ended scissors
- a tick remover
- disposable gloves
- a spare lead and a basket muzzle your dog is used to
- a torch
A first-aid kit is for cleaning minor scrapes and protecting injuries on the way to the vet. If a wound is deep, bleeding, or your dog keeps licking it, get it checked.
Minor problems
For something that doesn't look urgent, such as a small graze, a mild limp or one episode of being sick in a dog that is otherwise bright and eating, keep a close eye on them and phone your vet for advice. Book an appointment if it hasn't improved within a day or so, or straight away if it gets worse.
Before you decide
- Do you know where your nearest out-of-hours vet is and how to get there?
- Do you have a way to move a large dog if it can't walk?
- Is your first-aid kit stocked and somewhere everyone at home can find it?
Questions readers ask
What should I do first if my dog is injured?
Stay calm, make sure you are safe, then phone your vet or their out-of-hours service. Tell them what happened and follow their advice on the way in.
Can I give my dog paracetamol or ibuprofen for pain?
No. Human painkillers can poison dogs. Never give your dog any human medicine. Contact your vet, who can provide pain relief that is safe for dogs.
My dog ate chocolate but seems fine. Should I wait?
No. Phone your vet straight away and tell them what kind of chocolate, how much and when. Signs of poisoning can take hours to appear, and early treatment is more effective.

What if my vet is closed?
Call your vet's usual number. Most practices give details of their out-of-hours service on their answerphone or website. Save that number in your phone now so you have it ready.
Should I take a first-aid course for dogs?
It can help you feel more confident in an emergency. Even so, first aid only buys time: your dog still needs to see a vet.
