Shock in Dogs: Keep Them Warm, Still and Level

Shock kills quietly, after the loud thing has already happened. And the human first aid instinct, raising the legs, is wrong for dogs.

Shock is what follows the dramatic event: the road accident, the fall, the dog fight, the serious bleed, the severe allergic reaction. The noise is over, the dog is quiet, and something much more dangerous is now underway.

It means the body can no longer get enough blood and oxygen to its organs. It kills through organ failure rather than anything you can see, which is exactly why it gets underestimated in the moments after an accident.

What to do

1. Keep the dog warm, quiet and still. Wrap it in a blanket, speak softly, and keep people and other animals from crowding it.
2. If it is unconscious, keep the head level with the body.
3. Muzzle it if it is in pain, but never if it is vomiting or unconscious.
4. Ring the vet and go, telling them what caused it so they can prepare fluids, oxygen and theatre.
5. Drive smoothly, keeping the dog warm and the head level.

The mistake carried over from human first aid

Do not raise the hind legs.

Most of us were taught, somewhere, that you elevate the legs of someone in shock to send blood back to the heart. Dogs are built differently, and raising the back end presses the abdominal contents against the diaphragm and makes breathing harder for an animal that is already struggling to oxygenate.

Head level with the body. That is the veterinary position, and it is worth deliberately unlearning the other one.

Two more things not to do

Do not give food or water, however thirsty the dog looks. An anaesthetic is very likely at the other end, and a dog with reduced consciousness can inhale what you give it.

Do not over-warm it. A blanket, yes. A hot water bottle, hairdryer or heat pad, no. Active heat opens the blood vessels at the skin and pulls blood away from the organs that need it most, which is the opposite of what you are trying to achieve.

And do not wait to see whether the dog rallies. A dog that looks slightly better after five minutes can be in kidney failure two hours later.

What shock looks like

• A weak, fast, thready pulse, sometimes hard to find at all
• Shallow, rapid breathing, or panting that will not settle
• Pale, white, grey or muddy gums
• Cold ears, paws and tail
• Dazed eyes, a slow blink, a vacant stare
• Trembling, or weakness so severe the dog cannot stand
• Collapse, or only a partial response to your voice

Here is a check worth knowing. Press a finger on the gum until it blanches, then let go. The colour should come back within about two seconds. If it takes noticeably longer, circulation is failing and that is a genuine finding you can report on the phone.

A distended, tight belly alongside these signs points towards bloat as the cause.

Do not get distracted by measurements

If your dog has been hit by a car, has fallen, has been in a fight or has lost a lot of blood, assume shock and travel. Do not delay to take a temperature, count a pulse rate or gather numbers. The vet will do all of that properly in a few minutes' time.

The one thing worth doing on the way is telling them what happened, because shock is always secondary to something, and knowing whether they are preparing for a haemorrhage, a fracture or an allergic reaction changes what is waiting for you when the doors open.

Lift a badly injured dog on a board or a taut blanket rather than by the scruff or the legs, keeping the spine as neutral as you can.
