Dog carriers vary from all wire kennels with or without dividers to the airline approved pet carriers sized from cat sized to giant breed sized.
Choosing the right dog carrier depends on what you are wanting from it. There are advantages and disadvantages to several kinds and it depends on the size of your dog. Increasingly, those traveling with small dogs find a designer dog carrier such as a Sherpa is convenient and meets airline regulations for traveling in the cabin.
A small dog carrier can also be a good idea for your small dog in the car. Inside their carrier, seat belted into the passenger seat with the door towards you allows your dog to travel safely and be protected in case of an accident. A dog carrier is a good idea for large dogs in the vehicle too, with far too many tragic incidents of dogs surviving the accident then getting lost in the aftermath.
A pet carrier might be the harder plastic crates made for air travel or the wire crates. Some of these have a divider for larger crates, allowing two dogs in the crate but separated or keeping a large breed puppy in one end, allowing more room as the puppy grows.
These wire crates can be good in the home, with several types of covers available to help fit in the décor. These wire crates have several types of covers available from a wicker look to seasonal ones. The advantage to these wire crates is more ventilation and visibility, but they aren’t as strong to protect the dog as the solid dog crates are.
Less portable crates can be found appearing like an end table but with an area for a small dog bed and a wooden door if needed to put the dog in the crate. The most common as far as dog carriers however is the airline type crate and the wire crates.
The proper dog carrier should be large enough for your dog to stand up and turn around. Room for a soft bed and a few chew toys is good also to make it comfortable as well as giving a young dog something to do.
