4Knines Hard Bottom Extender Car Seat Cover for Dogs - Regular

This a great product for a great price!! Fits my Durango perfectly and already tested out for waterproof with a throw up and a potty accident,, everything wiped off cleanly!!! No I need one for my 300.

I am so pleased with this seat extender for my dog. It is very sturdy and the door flaps are easy to undo to take my dog in and out. The latch hooks to keep it stable are the deal maker!

Fits nice in my 2015 gmc terrain. Have two medium dogs that love laying on it for car rides.
