How are dogs transported on planes and what measures are taken to ensure their safety and comfort during the journey?

Dogs are typically transported on planes in special crates in the cargo hold or in the cabin with their owners. To ensure their safety and comfort, airlines have specific guidelines for pet travel, including proper crate size, ventilation, and temperature control. Some airlines also offer pet-friendly amenities, such as designated pet relief areas and trained staff to assist with pet care during the journey.
