Easy to setup and clean

This waterproof dog seat cover fits perfectly as a back seat extender, providing ample space for dogs. The scratch proof material is durable and the anti slip design keeps it securely in place. It’s easy to clean and protects the seats from dirt, fur and messes. A practical and well designed solution for car rides with pets.

Completely waterproof cover

The car seat cover is waterproof, it completely protects my backseat from muddy paws, hair, drool, and scratches. The full-coverage setup, including side flaps, ensures that both the seat and doors are well-protected, keeping my car clean and free from damage. The material feels durable yet comfortable, and the anti-slip backing keeps everything securely in place, even during longer trips. The mesh viewing window allows my dog to see me while reducing his anxiety, and the zippers on both sides make it easy to interact with him. The three storage pockets are incredibly handy for keeping his toys, leash, and treats organized. Installation was easy, and when not in use, it folds up compactly for easy storage.

Very sturdy

This folds up nicely for travel purposes. Blocks dogs from jumping into the front row as well as helped our dogs with no getting car sick as much. Great product for all your fur babies.

great car seat cover

This dog seat cover is great! It’s incredibly sturdy and holds up perfectly, even with my 103lb dog. The installation is very easy, and it stays firmly in place in the car. The material is great with waterproof, scratch-proof, which makes it super reliable and easy to clean. I’m extremely satisfied with this car seat cover

Has carrying case

I have had the soft bottom ones previously but this one is now my favorite. It is extremely durable. The carrying case is what ultimately sold me on it because I was irritated with my old one just taking up space in my trunk. I would recommend this cover to anyone that travels with pets.
