To prevent your Chihuahua from getting motion sickness and to keep your puppy or dog safe in the event of an accident, there are a few elements that you'll want the car seat to have:
1.
Easy to install.
While many owners keep their dog's car seat in place, if you need to move it in and out of the car, it should not be an inconvenience.
2. Raised.
These are also referred to as dog booster seats, and this is an important element to look for. The seat should be raised high enough that it gives your Chihuahua good line-of-sight.
3. Properly sized.
With the Chihuahua being the smallest toy dog that exists, you'll want the seat to be sized to his body. If it is too large, there will not be proper supporting structures around the dog.
4. Inner harness buckle.
Do not overlook this. The only way to keep a Chihuahua safe in the seat is to have him wearing a harness (more ahead) and then clip the inner buckle to the attachment on the harness. Never do a seat-to-collar connection; this can cause grave neck injury.
The harness & car seat combination:
If you don't have a harness for your Chihuahua, it may be time to strongly consider this. Not only is this needed in cars to secure a dog into the car seat, but a harness also helps prevent the terrible and devastating condition of collapsed trachea (common with toy breeds) that can occur when a dog is on leash and collar.
There are a few excellent harnesses that fit even the smallest Chihuahua puppies and dogs, are comfortable, and are very easy to put on.
A good one is
Funpet's Soft Mesh Dog Harness, which is designed for small dogs, puppies, and cats. It is made of breathable mesh and comes in 6 different colors.
