Dog Hit by Car: Emergency Steps and Hidden Injuries

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

A road accident is terrifying. Calm, careful action can make a huge difference.

Safety first

Check for traffic before approaching, and turn on hazard lights if you are in a vehicle. An injured dog may snap or run in panic. Speak softly and approach from the side.

Quick assessment

• Breathing: is he breathing, and how hard
• Gum color: pale, white, blue or bright red
• Bleeding: location and severity
• Consciousness: responsive or dazed
• Obvious fractures or wounds
• Pain and abnormal posture

If your dog is not breathing and has no heartbeat, begin CPR. See dog CPR and rescue breathing.

Immediate steps

1. Call the nearest emergency vet so they can prepare, and head there.
2. Muzzle gently if your dog is conscious, not vomiting and not struggling to breathe.
3. Control severe bleeding with firm pressure. See dog wounds and cuts.
4. Keep your dog warm with a blanket to reduce shock.
5. Move him carefully: slide a flat board, blanket or coat under him and lift with a helper, keeping the head and spine in a straight line.
6. Do not give food, water or medication.
7. Drive safely, with someone to monitor your dog.

Hidden injuries

• Lung contusions and pneumothorax causing breathing trouble
• Internal bleeding, often from the spleen or liver
• Bladder or diaphragm rupture
• Fractures, pelvis, spine and limbs
• Head trauma and concussion
• Heart rhythm problems
• Road rash and degloving wounds

Signs may appear hours later. A dog that seems fine still needs an exam, X-rays and monitoring.

What the vet will do

The clinic stabilizes with oxygen, fluids and pain relief, then assesses with exams, X-rays, ultrasound and bloodwork. Surgery may be needed for fractures or internal injuries. Dogs are usually observed for at least 24 hours.

Recovery

Healing depends on injuries and can take weeks to months. Follow rest and rehab instructions, manage pain and attend rechecks. See dog stitches and incision care.

Costs and planning

Emergency trauma care can be expensive. Ask for estimates, discuss options and consider insurance in advance. See dog emergency vet costs and dog pet insurance guide.

Prevention

• Keep dogs on leash near roads
• Secure fences and gates
• Train a solid recall. See recall training guide
• Microchip and ID your dog. See dog microchipping
• Use reflective gear at night
• Never let your dog roam

Common mistakes

• Moving the dog roughly
• Waiting to see if he is okay
• Giving food or water
• Assuming no injuries means no problem

Troubleshooting

• My dog ran off after impact: search calmly and call your vet.
• My dog seems fine hours later: still book an exam.
• My dog is vomiting after the accident: go to the vet immediately.

A simple plan

1. Check safety.
2. Call the vet.
3. Move gently.
4. Go to the clinic.

Real-life examples

A terrier hit by a slow car has a broken pelvis found on X-ray. A shepherd with no visible injuries is found to have bleeding in the abdomen. A lab recovers after surgery and rehab. Early exams save lives.

Stay prepared

Keep your emergency clinic's number and route handy.

Shock and what to expect

Shock causes pale gums, rapid breathing, a weak pulse and cold limbs, and it can be life-threatening even without obvious bleeding. Keep your dog lying down, covered with a blanket and handled gently. Do not give anything by mouth, and drive straight to the clinic.

Questions to ask your vet

Ask which tests are needed, what injuries have been found, what the likely cost is, how long monitoring will last and what home care involves. Ask about warning signs after discharge, such as difficulty breathing, vomiting and reluctance to walk.

The takeaway

Move gently, go to the vet immediately and expect an exam even if your dog seems fine.
