Overview

The GLENSLAVE S05 is a booster-style car seat for dogs up to 35 pounds, built with a memory foam and plush cushion, two safety belts, and a removable cover with storage pockets for gear on the go.

Sized for small to medium breeds, the seat elevates a dog to see out the window while two included safety leashes clip to a harness for the ride. The cushion and cover come off for washing, an important detail for a seat that collects fur and drool.

  • Rated for dogs up to 35 lbs
  • Machine or hand washable cushion and cover
  • Two adjustable safety belts included
  • Side storage pockets for leashes and gear

Who it's for

Owners of dogs under 35 pounds who want a car booster with washable padding and a built-in restraint, not a crash-tested carrier meant for larger breeds.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Detachable, washable cushion and cover
  • Two included safety belts
  • Storage pockets for leashes and supplies
  • Memory foam padding
What to check first
  • Weight capped at 35 pounds, unsuitable for larger dogs

Performance notes

The detachable cushion and cover are rated for machine or hand washing, which matters given the seat sits directly against a dog's coat on every trip. Two adjustable safety belts anchor to a harness rather than a collar, and side storage pockets hold leashes, bags or treats within reach of the driver.
