The backseat extender for dogs covers both the back seat and the gap between the front row, transforming the rear space into a cozy car mattress. Unlike standard car seat covers for dogs, this hard bottom dog seat cover is broader in the middle part. In case of sudden stops or emergencies, the back seat extender acts as a barrier, preventing dogs from falling out of the back seat protector. The dog back seat extender platform can support up to 280 Ibs, ensuring your dogs travel in comfort and safety.
