What Happens to Dogs in Cargo During Layovers — and Is It Safe?

During layovers, dogs in cargo either remain inside the aircraft’s pressurized hold or are transferred to a climate-controlled animal holding facility at the airport — it depends on the airline, the layover length, and the airport. The cargo hold is temperature-controlled in flight (typically 50–70°F), but conditions become unpredictable on the ground. Tarmac temperatures, loading delays, and lack of direct human monitoring make layovers the highest-risk part of cargo travel for dogs. Below, we cover exactly what happens at each stage, the real safety risks, airline-specific policies, and a safer alternative for domestic pet transport.

What Does the Cargo Hold Look Like for Pets?

To better grasp the safety measures taken for dogs during layovers, it’s essential to understand how air travel works for pets and the conditions in cargo holds.

1. Pet-Friendly Airlines: Many airlines are pet-friendly, accommodating the needs of traveling animals. They follow strict guidelines and regulations to ensure the safety and comfort of pets in cargo holds during flights and layovers.
2. Cargo Holds: The cargo hold is a pressurized and temperature-controlled compartment within the aircraft, specifically designed to transport animals and other sensitive items. This environment is intended to keep pets comfortable and safe throughout the journey, including layovers.

How Airlines Keep Dogs Safe During Layovers

Airlines take various measures to ensure that pets are safe and comfortable during layovers. These measures include:

1. Temperature Control: Airlines maintain a consistent temperature in the cargo hold throughout the flight and layovers. This ensures that dogs don’t experience extreme temperature fluctuations, which could cause stress or health issues.
2. Ventilation: Adequate ventilation is provided in the cargo hold, allowing dogs to breathe comfortably during layovers. This is essential for their well-being and prevents respiratory issues.
3. Pet Handlers: Many airlines employ trained pet handlers responsible for monitoring and attending to pets’ needs during layovers. They ensure that dogs have access to water and are comfortable during the layover period.
4. Short Layovers: If possible, choosing flights with shorter layovers is advisable. This minimizes your dog’s time in the cargo hold and reduces the potential for stress.

How to Prepare Your Dog for a Flight with Layovers

To further ensure your dog’s safety and comfort during layovers, you can take specific steps to prepare them for air travel:

1. Health Check: Schedule a visit to your veterinarian before the trip to ensure that your dog is healthy and fit for air travel. Obtain a health certificate and ensure that your dog’s vaccinations are current.
2. Proper Crate: Invest in a sturdy, well-ventilated crate that meets airline requirements. The crate should be large enough for your dog to stand, turn around, and lie down comfortably.
3. Identification: Attach identification tags to your dog’s collar and crate. Include your name, address, phone number, and final destination. This will help airline staff locate and identify your dog during layovers.
4. Acclimate Your Dog: Before the trip, acclimate your dog to the crate by allowing them to spend time inside it. This will help them feel more comfortable during air travel and layovers.

What to Do If Your Dog Needs Special Care During Travel

In case your dog has special needs or requires extra care, consider the following:

1. Inform the Airline: Notify the airline about your dog’s specific needs and requirements, and discuss the available options to ensure their comfort during layovers.
2. Medications: If your dog requires medication, provide the necessary supplies and instructions to the pet handlers, ensuring that they can administer the medications during layovers if needed.
3. Choose Direct Flights: Flying a dog with special needs, it may be best to choose a direct flight to avoid layovers altogether. This minimizes the potential for stress and ensures that your dog’s needs are met throughout the journey.

4. Hire a Pet Travel Specialist: If you’re concerned about your dog’s well-being during layovers, consider hiring a pet travel specialist. These professionals can help coordinate and manage your pet’s travel arrangements, ensuring their safety and comfort at every step of the journey.

Are Dogs Safe Flying in Cargo? Risks and Statistics

Flying dogs in cargo is generally considered safe, but it does come with risks that pet owners should understand before booking a flight. In the United States, airlines are required by the U.S. Department of Transportation to report all animal incidents, including injuries, losses, and deaths. According to recent reports, millions of animals are transported by air each year, and the vast majority arrive safely. However, there are typically a few dozen reported incidents annually, which—while statistically low—can be concerning given the stakes.

The primary risks associated with cargo travel involve temperature fluctuations, stress, and handling during loading and unloading. Cargo holds on most commercial planes are pressurized and temperature-controlled, but pets may still be exposed to extreme weather conditions while on the ground. This is why many airlines enforce seasonal restrictions, limiting pet travel during very hot or cold months.

Certain dogs face higher risks than others. Brachycephalic (flat-faced) breeds, such as Bulldogs and Pugs, are more prone to breathing issues, which can be exacerbated by stress or reduced airflow. Because of this, many airlines have strict limitations or outright bans on these breeds in cargo.

Another factor is human error or logistics issues, such as delays, misrouting, or improper crate handling. While rare, these incidents do occur and are often the cause of reported problems. To reduce risk, pet owners should use airline-approved crates, choose direct flights whenever possible, and avoid peak heat or cold seasons. It’s also important to confirm the airline’s pet safety protocols in advance.

For those uncomfortable with cargo travel, ground transport services like CitizenShipper offer an alternative where dogs travel with a driver in a controlled environment. While slower, this option eliminates many of the risks associated with cargo and provides more direct oversight throughout the journey.

Cargo Hold Temperature and Conditions During Layovers

Airplane cargo holds used for pet transport are typically pressurized and temperature-controlled during flight, but conditions during layovers and ground handling are where the biggest concerns arise. While in the air, most major airlines maintain cargo hold temperatures similar to the cabin, generally between 45°F and 75°F, which is safe for healthy animals traveling in approved crates.

However, during layovers, pets may spend time on the ground while being transferred between planes. During these periods, they can be briefly exposed to outside temperatures, which may be much hotter or colder depending on the location and season. This is why many airlines enforce weather embargoes, restricting pet travel when temperatures exceed certain limits (often above 85°F or below 45°F).

Airline staff are trained to minimize exposure time and often transport pets in climate-controlled vehicles or holding areas when available. Still, delays, long layovers, or busy airport conditions can increase the amount of time a pet spends outside controlled environments.

To reduce risk, pet owners should book direct flights whenever possible, avoid peak summer and winter travel, and confirm airline-specific temperature policies before booking. For those concerned about extended layovers or temperature exposure, ground transport services provide a more consistent, climate-controlled alternative throughout the entire journey.

New CDC Rules for Flying Dogs into the United States

The CDC has recently passed new laws regarding flying with pets. These new rules are intended to limit rabies exposure in the United States. Due to these new rules, American Airlines has embargoed pets from flying into the United States from countries or territories considered “high risk” for rabies, or if the pet has been in a high-risk location within the past six months.

Frequently Asked Questions About Dogs in Cargo

To provide further clarity, we’ve compiled answers to some frequently asked questions about dogs in cargo during layovers.

Ground Transport: A Safer Alternative to Cargo Flights

While air cargo can be a necessary option—especially for international relocations—it’s not always the ideal choice for domestic pet travel. As outlined above, cargo transport introduces variables like temperature exposure, handling risks, and limited monitoring during transit. For many pet owners, particularly those traveling within the U.S., ground transport offers a safer, more controlled alternative that eliminates many of these concerns.

With ground transportation, pets travel in a climate-controlled vehicle alongside a dedicated driver, allowing for regular breaks, constant supervision, and a significantly less stressful experience overall. There’s no cargo hold, no long layovers, and no uncertainty about your pet’s condition during the journey.
