The van is actually a minibus and is very roomy. It has two sliding side doors as well as the two doors at the back. There are windows all around so natural light floods in.
There are sliding windows which allow for lots of ventilation in the summer. The van also has a good heating/cooling system so whatever the temperature, your pet will be comfortable.
All pets travel in crates as shown. There is also a portable shower available for mucky/muddy situations.
