Frequently Asked Questions
How do I size a booster for my small dog?
Measure your dog’s length from chest to rump and compare to the booster’s internal floor dimensions. Also check the weight recommendation — if your dog is near the limit, choose the next size up to allow comfortable movement and prevent crowding.
Can my dog stay in a booster without a harness?
No. For safety, always attach the booster’s tether to a properly fitted dog harness (not a collar). The tether and harness together reduce the risk of neck injury in a sudden stop and keep your pet secure.
Are memory foam boosters worth it?
Memory foam is worth it for longer drives or dogs that need extra shock absorption. It provides superior comfort and reduces fatigue, but tends to be heavier and higher-priced than basic fleece-lined options. If you prefer easy washing, verify whether the foam is removable or only the cover is machine-washable.
