* Car size: A small Smart car will hold far fewer dogs than a large SUV.
* Dog size: A Chihuahua takes up much less space than a Great Dane.
* Dog behavior: Are the dogs friendly and willing to sit close together? Are they prone to jumping around?
* Safety: It's crucial to prioritize safety. Dogs should be secured in crates or with harnesses and seatbelts to prevent injury during a sudden stop or accident.
Instead of focusing on the number, consider these factors:
* Is there enough space for each dog to stand up, turn around, and lie down comfortably?
* Are the dogs secured safely and comfortably?
* Are there any potential hazards in the car (e.g., loose objects, hot surfaces)?
Always remember, it's better to err on the side of caution. If you're unsure, it's best to transport your dogs in multiple trips or find a larger vehicle.
