Non-service dogs must be in a kennel
Chicago O'Hare International Airport is a very animal-friendly airport, with four pet potty areas that are easily accessible. Three of these areas are outdoors, located outside Terminals 1, 2, and 5, and one indoor pet relief area can be found in the Rotunda area of Terminal 3. However, non-service dogs must be kept in a kennel or crate at all times, except when going through security or using the relief areas. This rule is always in place and can be enforced at any time, so it is best to keep your dog in a kennel to avoid missing your flight or being fined.
If your dog is travelling as cargo, you will need to pick them up and drop them off at the designated cargo facility for your airline. O'Hare's cargo facilities are located within the same road loop, and while there is no shuttle service, the area is easily accessible by road. If your dog is travelling as checked baggage, you will check them in at the airline counter and pick them up in the excess baggage section of your arrival terminal, usually at baggage claim in Terminal 5.
It is important to note that each airline has different requirements and rules for pet transport, so you must notify your airline in advance if you plan to travel with your dog. Some airlines have restrictions on the number of pets per flight, and larger dogs that are not service animals will likely be transported in the cargo hold. Most major airlines allow small dogs to accompany passengers in the cabin, usually with a weight limit of 15 to 20 pounds, as long as they are secured in a TSA-approved travel crate.
Before travelling with your dog, it is essential to ensure they are up to date on all medications and vaccinations and any other requirements for your destination country, such as blood tests, microchips, permits, or health certificates. Additionally, acclimating your dog to their travel crate several weeks or months in advance can help reduce their stress during air travel.

Airlines have different pet rules
While O'Hare Airport in Chicago is considered a very animal-friendly airport, with four pet potty areas, the general rule is that animals are not allowed inside the buildings unless they are service dogs. Therefore, if you are waiting to pick someone up from the airport, it is advised that you do so outside.
Now, when it comes to air travel with pets, each airline has its own set of rules and regulations. For example, American Airlines does not accept pets that have been sedated or tranquilized, whereas United Airlines allows trained service animals and emotional support animals with proper documentation.
Additionally, some airlines have restrictions on the number of pets allowed per flight, so it is essential to notify your airline in advance if you plan to travel with your pet. Most major airlines allow small dogs to accompany passengers in the cabin, provided they weigh no more than 15 to 20 pounds and are secured in a TSA-approved travel crate. However, larger dogs that are not service animals will likely need to travel in the cargo hold, and some may even need to travel as cargo on a separate flight.
Furthermore, certain countries have specific requirements for pet entry, such as microchipping and vaccinations, and it is the owner's responsibility to be aware of these regulations. It is also important to ensure your pet is healthy and up to date with any necessary medications and shots before travelling.
Overall, while O'Hare Airport accommodates pets with its designated relief areas, the policies for travelling with pets vary across different airlines, and it is crucial to understand these policies to ensure a smooth travel experience for both owners and their furry companions.

There are various factors to consider when deciding whether to transport your dog as cargo. Firstly, air travel can be stressful for dogs, and they may find it traumatic to be confined in a loud, dark and cramped space for long periods.
