Use a restraint made for vehicle travel on every ride, secure it as the manufacturer directs, and keep your puppy in the back seat. Choose a vehicle-specific harness, carrier, or crate that fits your puppy and can be secured properly in your vehicle; a walking harness, collar, or loose leash is not a substitute.
Choose a restraint that fits your puppy and your vehicle
There is no single restraint that is best for every puppy or car. Base your choice on your puppy’s size and fit, whether they chew or move around, their comfort with confinement, the vehicle’s layout, and how securely the restraint attaches. The Center for Pet Safety (CPS) recommends: “Use CPS Certified® harnesses, crates, or carriers whenever possible.” Check its current certified product list for the exact model and configuration; a general claim that a product is “crash-tested” does not identify a shared standard.
| Option | When it may suit your puppy | What to verify |
|---|---|---|
| Vehicle-specific car harness | Your puppy fits the maker’s size range and can wear the harness comfortably. | Use a harness designed for vehicle travel and connect it exactly as its maker specifies. Check whether the exact product and configuration appear on CPS’s list. Do not treat a walking harness or collar as crash protection. AAA explains vehicle restraint guidance. |
| Carrier | Your puppy is small enough to fit appropriately and is more comfortable contained. | Secure it as directed and assess its testing or certification status. A carrier described as a travel carrier is not automatically crash protective. The American Kennel Club’s puppy transportation guidance recommends securing a puppy in a carrier. |
| Crate | Your puppy can be accommodated in a properly sized crate that fits the vehicle. | Confirm how the crate is secured and, for cargo-area placement, verify anchor ratings and platform capacity with the vehicle manufacturer. Use strength-rated crate straps. CPS’s cargo-area advisory reports reduced crate excursion with proper anchoring in its 2015 study; that finding does not establish protection for an untested crate or anchor. |
AAA says there are no government standards or industry tests for pet restraints. Treat “crash-tested” as an incomplete marketing claim unless you can identify what was tested and whether the exact product is on a credible certification list. CPS certification is a voluntary independent program, not a universal government standard.
Set up the ride safely
- Fit the restraint before driving. Check that your puppy fits the chosen equipment and that every connection follows the manufacturer’s instructions.
- Use the back seat. Keep your puppy away from the front-seat airbag area. A loose puppy can interfere with the driver’s visibility and controls, and a restraint limits movement during sudden stops.
- Do not let your puppy ride loose or on a lap. A leash or walking harness alone is not a vehicle restraint. Avoid extension tethers and zipline-style products: CPS warns that the extra movement can increase risk during sudden deceleration and undermine claimed crash protection. See its extension-tether safety warning.
If the crate is in the cargo area
Ask the vehicle manufacturer whether the cargo anchors are strength-rated and what load they can support. Use strength-rated crate straps rather than elastic or rubber bungee cords. The load includes both the crate and the puppy, so a hook’s appearance alone does not show that it is adequate. CPS’s 2015 Crate Crashworthiness Study found that proper anchor straps significantly reduced crate excursion into the seatback or passenger compartment; the advisory does not give a numeric effect size.

Help your puppy get comfortable before a trip
- Start at home. Put the restraint where your puppy can investigate it. Reward calm approaches with praise and small treats, and keep practice sessions short.
- Practice getting into the car. Once your puppy is comfortable with the equipment, rehearse getting in and settling in the restraint before you need to leave.
- Take a brief practice drive. Begin without a planned trip so you are not rushed. Reward calm behavior; for longer journeys, acclimate ahead of time and plan breaks.
The AKC’s car-training guidance recommends gradual practice with treats and praise. This can help your puppy become familiar with travel, but it does not guarantee a particular behavioral outcome.

- Confirm that the restraint is intended for vehicle travel, fits your puppy, and is installed in the configuration its manufacturer specifies.
- For a CPS Certified option, check the current list for the exact product rather than relying on a brand name or broad advertising claim.
- For cargo-area crate use, confirm anchor ratings and capacity with the vehicle manufacturer.
- Verify local rules where you drive; requirements are not established as uniform across jurisdictions.
In a 2026 Florida Consumer Pulse survey conducted online August 5–13 among 201 dog owners, AAA Auto Club Group reported that one in four Florida dogs ride unrestrained in vehicles. AAA gave a maximum margin of error of ±6.9 percentage points, so this is a Florida survey result, not a national estimate. AAA Auto Club Group’s survey report.
