Many dog owners enjoy having their dog along for the ride. But if you plan to leave your dog in the car while you shop, eat at a restaurant, pick up a prescription, or run another errand, it is important to understand the potential risks and plan ahead.

However, bringing your dog with you also creates an important responsibility: What happens to your dog when you arrive somewhere the dog cannot go inside?

Leaving a dog unattended in a vehicle—even for what seems like a few minutes—can become dangerous much faster than many people realize. Dog owners should also understand the difference between pet-friendly businesses and locations where ordinary pets generally do not belong.

Before You Take Your Dog, Think About the Entire Trip

Before putting your dog in the car, ask yourself:

Can my dog safely accompany me everywhere I plan to go?

If the answer is no, leaving your dog comfortably at home may be the better choice.

A trip to the park, a pet-friendly store, or an outdoor destination may be perfectly appropriate for your dog. A trip involving grocery shopping, eating inside a restaurant, medical appointments, or extended errands may not be.

Planning ahead prevents you from arriving at your destination and realizing your only options are taking your pet somewhere it should not be or leaving it unattended in the vehicle.

Why You Shouldn’t Leave Your Dog in the Car

The temperature inside a parked vehicle can rise rapidly, even when the outside temperature does not seem particularly hot.

Dogs do not regulate their body temperature the same way humans do. They primarily cool themselves through panting, and an enclosed, increasingly warm vehicle can quickly overwhelm their ability to stay cool.

Cracking the windows is not a reliable way to keep the vehicle at a safe temperature.

Heat-related illness can become life-threatening and may result in:

• Excessive panting or drooling
• Weakness or difficulty standing
• Confusion or disorientation
• Vomiting
• Rapid heart rate
• Collapse
• Seizures
• Organ damage
• Death

Puppies, senior dogs, overweight dogs, dogs with medical conditions, and short-nosed breeds such as Bulldogs, Pugs, and Boston Terriers can be particularly vulnerable to heat.

“I’ll Only Be Gone for Five Minutes”

Many owners leave their dog in the car believing they will only be gone for a few minutes.

You may intend to be gone for only five minutes, but circumstances can change.

The checkout line may be longer than expected. You may run into someone you know. The store may not have what you need. A prescription may not be ready. There may be a problem at the register.

Five minutes can easily become fifteen or twenty.

When your dog’s safety depends on exactly how quickly you return, an ordinary delay can become a serious problem.

What About Leaving the Air Conditioning Running?

Some owners leave their vehicle running with the air conditioning on while their dog remains inside. Certain newer vehicles also have climate-control or “dog mode” features.

These features can reduce risk, but they should not create a false sense of security.

Vehicles can malfunction. Engines can shut off. Climate-control systems can fail. Settings can be accidentally changed, and electronic systems are not infallible.

If you use a vehicle’s climate-control feature for your dog, understand exactly how the system operates and its limitations. Never assume that technology completely eliminates the risks of leaving an animal unattended.

Dogs and Grocery Stores

Unless your dog is a trained service animal that qualifies for public access under applicable law, your pet generally should not accompany you into a grocery store.

Grocery stores sell and handle food and are subject to health and sanitation requirements. A store allowing trained service animals does not mean it is required to allow ordinary pets.

The same principle applies to many restaurants and other establishments that prepare or serve food.

A dog being friendly, well-trained, small enough to carry, or riding in a shopping cart does not make the dog a service animal.

Leaving Your Dog in the Car: Service Dogs Are Different From Pets

The decision to leave your dog in the car can become especially complicated when considering public access, because service dogs and ordinary pets are treated differently under the law.

Under the Americans with Disabilities Act (ADA), a service animal is generally a dog that has been individually trained to perform work or tasks for a person with a disability.

Service dogs may have public-access rights in places where ordinary pets are not permitted, including many grocery stores and restaurants.

Emotional support, comfort, or companionship by itself does not give a dog the same public-access rights under the ADA.

Business owners and customers should also respect legitimate service-dog teams. Distracting, petting, calling to, feeding, or allowing another dog to approach a working service dog can interfere with the dog’s job.

Restaurants and Dogs

Ordinary pets generally should not be brought into indoor restaurant areas where pets are prohibited.

Some restaurants may legally allow pet dogs in designated outdoor seating or patio areas, depending on state and local regulations and the establishment’s policies.

Always check before bringing your dog.

Even at a dog-friendly patio, your dog should be capable of remaining calm around people, food, servers, children, and other dogs.

A dog-friendly location does not automatically mean every dog is ready for that environment.

Never Pretend Your Pet Is a Service Dog

Dog owners should never misrepresent a pet as a service animal simply to gain access to a business where pets are prohibited.

Service-dog access exists so people with disabilities can be accompanied by dogs specifically trained to perform disability-related work or tasks.

Misrepresenting an ordinary pet as a service dog can create problems for businesses and for people who genuinely depend on trained service dogs.

Responsible dog ownership includes respecting these boundaries.

Consider Your Dog’s Behavior Before Bringing Them Along

Temperature is not the only consideration.

Ask whether your dog is comfortable traveling and being around unfamiliar environments.

A dog that experiences severe separation anxiety, barrier frustration, territorial behavior, or reactivity may become extremely stressed when left alone in a parked vehicle.

Some dogs may:

• Bark continuously
• Scratch doors or windows
• Attempt to escape
• Become destructive
• React aggressively toward people approaching the vehicle
• Become increasingly anxious when their owner disappears

If your dog cannot remain calm and comfortable, leaving the dog in the vehicle is not an appropriate training solution.

Better Alternatives to Leaving Your Dog in the Car

Rather than leave your dog in the car while you run errands, consider whether your dog would be safer and more comfortable at home.

If your errands involve places your dog cannot safely or legally accompany you, consider another option.

Leave your dog safely at home, have another responsible adult remain with the dog, complete dog-friendly activities separately from shopping trips, use curbside pickup or drive-through services when available, or plan your errands before or after your dog’s outing.

Sometimes the most responsible decision is simply not bringing the dog along.

When You Do Take Your Dog With You

Dogs can benefit from appropriately planned trips to parks, walking trails, pet-friendly businesses, training locations, veterinary appointments, and other suitable destinations.

Your dog should be safely secured while the vehicle is moving using an appropriate restraint, carrier, or other safe transportation method.

Training your dog to calmly enter the vehicle, settle during travel, wait before exiting, and respond reliably around distractions can make outings safer and more enjoyable.

Responsible Dog Ownership Means Planning Ahead

Taking your dog with you should be enjoyable for both you and your dog. Before you leave your dog in the car during any stop, consider the temperature, how long you may be gone, your dog’s comfort, and whether there is a safer alternative.

Before leaving home, consider:

Where am I going?
Is my dog permitted there?
Will my dog be comfortable?
Could I have to leave my dog unattended?
What happens if my five-minute stop becomes twenty minutes?

If you cannot confidently provide a safe answer, your dog may be better off staying home.

A responsible dog owner does not simply ask, “Can I bring my dog?”

The better question is:

“Is bringing my dog the safest and most appropriate choice for my dog today?”
