While there are many options available, most Service Dog handlers use one of the following two techniques:

1. Put a crate in the back of your SUV (or in the back seat of your car), and then have the dog jump up into the crate.
2. Have the dog wear his/her Service Dog vest (which has a handle on it), and string the seatbelt through the handle.

Either of these options keeps the dog safe and secure.
