Pet travel is the process of traveling with or transporting pets. Pet carriers like cat carriers and dog crates confine and protect pets during travel.

Pets may experience stress and anxiety in unfamiliar situations or locations. Cats are especially stressed by change. Instead of travelling with their owner on vacation, pets can be boarded at kennels or kept at home with a friend or pet sitter. However, that also includes unfamiliar situations and locations. This is not an option when moving permanently.

Pets may travel in the aircraft cabin, checked baggage, or as cargo. However, airlines set their own policies regarding the travel of pets. Some major airlines have discontinued pet cargo and now allow only in-cabin travel. Most airlines also charge for emotional support animals. Pet Airways specialised in transporting pets but later ceased operations. In recent years, private-jet pet travel has gained momentum especially due to discounted flight sales. In such travels pets are allowed in the cabin with their owners, which reduces stress and trauma. However, unlike flying commercial airlines where ticket fees are paid one-off up-front, there may be extra costs involved in private jet flights with pets onboard, such as cleaning fees and de-icing fees. These costs may only be known post-flight.

The Humane Society of the United States recommends avoiding air travel if possible. Extreme temperatures and thin air have extra risk for brachycephalic animals such as bulldogs, Pekingese dogs, pugs and Persian cats. The United States Department of Transportation Air Travel Reports recorded 302 deaths, injuries and disappearances over 6 years with 35 deaths in 2011. At least two dogs died on United Airlines flights in 2012.

If pets escape, they can face danger, even if they escape on the ground. A cat named Jack escaped from his carrier in American Airlines' baggage handling at John F. Kennedy Airport, went missing for 61 days, and was eventually euthanized. Another cat escaped and was run over by a vehicle on the tarmac at Indira Gandhi International Airport in Delhi, India when traveling with Jet Airways.

In 2018, United Airlines admitted to forcing a passenger pet to be stowed away in an overhead bin, resulting in the animal's death. Only two days later, another dog aboard a United flight was mistakenly sent to Japan instead of its intended Kansas City destination. A similar incident occurred in March 2018 when Delta Air Lines sent a puppy to Salt Lake City instead of its intended Boise destination.

Pets riding in cars are safest contained in carriers tied with a seat belt. They are advised to be in the back seat or have the airbags turned off. Dog harnesses can restrain but the Center for Pet Safety found "a 100 percent failure rate to protect either the consumer or the dog". Unrestrained pets can interfere with driving and can be seriously injured in an accident, but no states require pets to be secured in cars.

Smaller domestic animals can be ambulated locally in a pet stroller pushed or pulled by a human; this may be especially useful for ill, lame, and elderly creatures. A pet stroller is similar in design to a baby stroller. The stroller may be enclosed with netting to prevent escape while allowing the pet to view, hear, and smell the ambient environment. Unlike a human infant, the animal is not immobilized in the stroller, but is free to move about within it.
