One is a plastic flight box for pets, the other is a wooden cage, and the other is a cage with a steel inner frame and wooden packaging on the outside (mainly suitable for large bulldogs, such as Tibetan mastiffs, etc.).

These three pet transport cages have their own advantages and disadvantages and are suitable for the following different situations:

　1. Plastic pet flight box

The advantages are that it is portable, lightweight, and detachable, which can reduce the space occupied when not in use. The disadvantage is that the strength is limited and is generally only used for medium and small dog breeds. It is easy to be damaged and pets may escape.

　2. Wooden cage

Advantages are strong, durable, safe and reliable. However, they are bulky, have high production costs, are relatively expensive on the market, and take up space. Generally suitable for medium-sized dog breeds and not easily damaged.

　3. Wooden reinforced steel structure cage

Advantages are strong, durable, safe and reliable, high production cost, high market price, and occupying space. Only suitable for aggressive dog breeds and large dog breeds, it is not easily damaged and can be reused many times.

Specifications of commercially available flight cases:

Currently, the most popular pet flight boxes on the market are made of plastic. The specifications are:

49*32*32cm; 59*40*38cm; 67*50*45cm; 79*56*57cm; 100*68*83cm, etc., among which the first three specifications are the most widely used. The latter two large sizes are less commonly used. Because wooden cages are safer for medium and large dogs.

Wooden cages and cages with wooden steel structures generally need to be customized. There are no mass-produced manufacturers on the market. The required specifications must be made in accordance with the requirements of the "Live Animal Rules".
