Yes, dogs can be electrocuted. The most common cause in small animals is chewing on an electrical cord, though lightning, downed power lines, and faulty circuits can also cause electrical injury [1]. The result can range from a mild zap and a scared dog to cardiac arrest, so knowing what to look for and how to respond matters.

Quick Answer

Chewing electrical cords is the most common cause of electrical injury in small animals, and death usually results from cardiac or respiratory arrest [1].
Never touch a dog that is still in contact with a live wire. Cut power at the breaker or unplug the cord first, or you can be shocked too.
Signs include singe marks, burns in or around the mouth, collapse, trouble breathing, drooling, and seizures [1][2][3].
Electrical injury is always an emergency. A dog can look fine for minutes to hours and then develop breathing failure or seizures [2][3].
Even a dog that seems normal after a shock needs same-day veterinary evaluation.

What a Dog Electric Shock Looks Like

What is normal

A healthy dog breathes quietly and easily, has pink gums, stands and walks normally, and responds to you. Small amounts of clear drool are normal. A dog with a normal mouth may have some tartar or mild gum redness, but no burns, blackened tissue, or singed fur.

What an electric shock looks like

The signs of electrical injury vary with how much current passed through the body and where it entered. Common findings include:

Burns or singe marks. These often appear at the corners of the mouth, on the lips, or on the tongue after a dog chews a cord. In severe cases, burns can be deep, with blistered or ulcerated tissue and exposed muscle or bone [4].
Sudden collapse or a brief loss of consciousness. Mild cases may cause a temporary loss of consciousness [1].
Trouble breathing. A dog may stand with elbows out and neck stretched, pant, or breathe with obvious effort. This can signal fluid building up in the lungs, a known complication of electric shock [2].
Drooling, pawing at the mouth, or reluctance to eat. Mouth pain from burns is a common reason.
Seizures. Seizure activity can begin after the shock, sometimes hours later, and can be severe [3].
Muscle damage or fractures. Severe muscle contractions during a shock can break bones or damage muscle [1].

Some dogs show no burns at all. In one reported case, a dog tangled in an electric fence had no electrical burn injuries, yet later developed severe seizures [3]. That is why a normal-looking mouth does not rule out a serious injury.

Main Causes of Electric Shock in Dogs

Cause	Typical clues	How urgent
Chewed electrical cord	Chewing damage on a cord, burns at the mouth corners, dog found near an outlet	Emergency now
Electric fence contact	Dog tangled in fencing, no visible burns, drooling, collapse, seizures	Emergency now
Downed power line or outdoor wiring	Dog found outdoors near a downed line, may be unconscious	Emergency now, do not approach
Lightning strike	Dog found after a storm, often with collapse or sudden death	Emergency now
Faulty circuit or exposed wiring in the home	Dog found near a sparking outlet or damaged appliance	Emergency now

Cord chewing is the leading cause in small animals [1]. Puppies and young dogs are at higher risk because they explore with their mouths. A reported case involved a 3-month-old puppy who lost consciousness briefly after chewing a household cord, then developed serious breathing problems [2].

Electric fences are another risk, especially for dogs in rural areas or on farms. A dog can become entangled and stay in contact with the current for a long time. One dog was entangled for 1 to 2 hours and arrived at the emergency service unable to stand, with heavy drooling, panting, and a rapid heart rate [3].

Other household hazards that carry electrical or burn risk include batteries and small magnets. If your dog swallowed a battery, that is a separate emergency covered in My Dog Ate a Battery: Is This an Emergency?. Swallowed magnets are also dangerous and are discussed in Dog Ate a Magnet: Why It's an Emergency and What to Do.

Red Flags That Make It an Emergency

Call an emergency veterinary hospital right away if your dog has any of these:

You saw or suspect contact with a live electrical source, even if the dog seems fine.
Loss of consciousness, even briefly [1].
Trouble breathing, noisy breathing, or a stretched-out posture [2].
Seizures or twitching [3].
Burns, singe marks, or blackened tissue in the mouth or on the body [1][4].
Collapse, weakness, or inability to stand [3].
A very fast or very slow heart rate, or gums that are pale, blue, or white.
Drooling that will not stop, or refusal to eat or drink after a shock.

Breathing problems can worsen quickly. In the reported puppy case, oxygen support alone was not enough and the dog needed mechanical ventilation [2]. Seizures after electrocution can also be hard to control and may require intensive care [3]. Time matters.

Safe Things You Can Do at Home

Your first job is to protect yourself. Electricity travels through the dog and anything touching it, including water, metal, and you.

Cut the power first

Do not grab your dog if it may still be in contact with a live wire. Turn off the power at the breaker box or unplug the device if you can do so safely without touching the dog or the damaged cord. Only after the power is off should you touch your dog.

Then check and support your dog

Once the power is off:

Check breathing and pulse. If your dog is not breathing and has no pulse, start CPR. Our guide on Emergency First Aid for Dogs: Choking Burns Fractures and CPR Guide walks through the steps.
Keep your dog warm and calm. Wrap it in a towel or blanket and limit movement.
Do not put anything in the mouth. Do not apply ointments, butter, or human burn creams to mouth burns. Do not try to rinse the mouth if your dog is struggling, since that risks choking.
Do not give food, water, or any medication by mouth. A dog with breathing trouble or seizures should not eat or drink.
Call the emergency hospital while you are on the way. Tell them a possible electrocution happened so they can prepare.

If your dog has burns on the body from a heat source, cool the area with room-temperature water and cover it with a clean cloth. Do not use ice. More burn first aid steps are in the first aid guide linked above.

Watch for delayed signs

Signs can appear after a quiet period. Keep your dog quiet and watch breathing, gum color, and behavior closely during transport. If breathing gets worse, tell the veterinary team as soon as you arrive.

What the Veterinarian Will Check and Test

Your veterinarian will start with a full physical exam, including a careful look inside the mouth for burns and singe marks [1]. They will listen to the heart and lungs, check gum color, and assess neurologic status.

Testing depends on your dog's signs. Common steps include:

Oxygen and breathing support. A dog in respiratory distress may need oxygen by nasal catheter or, in severe cases, mechanical ventilation [2].
Chest imaging. X-rays or point-of-care ultrasound can show fluid in the lungs, a complication called pulmonary edema that has been reported after electrocution in dogs [2].
Heart monitoring. An ECG checks for rhythm problems. Electrical injury can cause dangerous heart rhythms, and death usually results from cardiac or respiratory arrest [1].
Blood work. This checks for muscle damage, organ changes, and electrolyte problems. Severe muscle contractions can cause muscle damage [1].
Seizure treatment. If seizures occur, the team may start antiseizure medication and escalate treatment if seizures do not stop [3].
Wound care. Burns are cleaned, protected, and managed. Deep burns may need more advanced care.

Supportive care is the mainstay for animals that survive the initial event [1]. Your veterinarian will tailor treatment to your dog's specific injuries and calculate any medication doses based on your dog's weight and health.

Prevention and Monitoring

Prevention is simple and highly effective.

Manage cords. Hide, cover, or unplug electrical cords when you are not using them. Cord protectors and cord concealers help. Puppies and chewers need the most supervision.
Unplug when away. If your dog is home alone and prone to chewing, unplug lamps, chargers, and small appliances in reach.
Check fences. If you have an electric fence, inspect it regularly and keep your dog away from the wire. Entanglement is the danger, not just a single zap [3].
Supervise outdoor time. Keep dogs away from downed lines after storms. Never let a dog approach a downed power line.
Watch after any shock. Even if your dog seems fine, keep it quiet and watch breathing, gum color, and behavior for the rest of the day. Call your veterinarian if anything changes.

If your dog has a habit of chewing cords, mention it at your next routine visit. Your veterinarian can help you build a plan and check for other chewing-related risks. For heat-related emergencies, see Dog Heat Stroke: How to Tell If It's an Emergency and Cool Your Dog Safely.

Limitations and When to Contact a Veterinarian

This article covers general information only. Every dog is different, and individual cases need a veterinarian who can examine your dog and run the right tests.

Emergency now: any contact with a live electrical source, loss of consciousness, breathing trouble, seizures, collapse, or burns in the mouth or on the body. Go to an emergency hospital immediately.
Same day: your dog chewed a cord but seems normal, has mild drooling, or has a small area of concern in the mouth. Call your veterinarian and expect to be seen the same day.
Routine visit: your dog is a known cord chewer and you want help with prevention, or you have questions about home safety. Bring it up at your next appointment.

Do not wait to see if signs develop on their own. Delayed breathing problems and seizures are well documented after electric shock in dogs [2][3].

Frequently Asked Questions

Can a dog survive being electrocuted?

Yes, many dogs survive with prompt care. Survival depends on how much current passed through the body and how quickly treatment starts. Supportive care is the main treatment for dogs that survive the initial event [1].

What happens if a dog gets electrocuted?

The current can disrupt the heart and breathing, causing cardiac or respiratory arrest, which is the usual cause of death [1]. Dogs that survive may have burns, breathing problems from lung fluid, seizures, or muscle and bone injuries [1][2][3].

Can dogs get electrocuted by a phone charger or low-voltage cord?

Any cord carrying household current can cause injury if a dog bites through it. The severity depends on the current, the path through the body, and how long contact lasts. Treat any chewed live cord as a possible electrocution and call your veterinarian.

How do I know if my dog chewed an electrical cord?

Look for chew marks, exposed wire, or a cord that no longer works. Check your dog's mouth for burns, singe marks, or drooling. A dog may also act scared, hide, or refuse food after a shock.

Can an electrical burn in a dog's mouth heal on its own?

Some minor burns heal with veterinary care, but mouth burns can be deeper than they look and can become infected. A veterinarian should examine any burn in or around the mouth. Deep burns may need ongoing wound care.
