Dog carriers are portable containers designed to transport dogs safely and comfortably. They come in various styles, including soft-sided, hard-sided, and backpack carriers, catering to different sizes and breeds of dogs. Many carriers feature ventilation openings, padded interiors, and secure closures to ensure the pet's safety during travel. These carriers are popular for trips to the vet, air travel, or simply for taking dogs on outings. Some models are designed to fit under airline seats, while others are suitable for car travel. Choosing the right carrier depends on the dog's size, temperament, and the intended use, ensuring a pleasant experience for both the pet and owner.
