Please check the Fit Guide before ordering.
Most back seats stop at the seat edge, leaving an open footwell below. Houndvia extends a hard-bottom platform over that space, giving your dog more room and a more stable place to ride.
More room. No open footwell. A more stable place to ride.
Houndvia uses a hard-bottom load-bearing structure to create firm support over the footwell, helping turn the rear seat into a larger, more stable platform for your dog.
Supports up to 270 lbs.
Larger dogs need more than just a seat. By extending usable space over the footwell, Houndvia gives them more room to stand, turn, stretch out, and settle in for the ride.
Built with road trips, longer drives, and everyday car travel in mind.
From weekend drives to longer road trips, Houndvia gives your dog a more comfortable place to settle in while helping keep the back seat ready for the journey.
More usable space means more room to stretch out after hikes, camping trips, and everyday adventures.
Helps protect the rear seat from spills, wet paws, and everyday travel mess.
Keeps airflow open between the front and rear cabin while allowing your dog to see forward.
Extended side panels help protect the rear doors from dirt, hair, and scratches.
Built-in storage and access points keep everyday travel essentials within reach.
Designed for most sedans, SUVs and pickup trucks. Vehicle interiors vary, so please check the product dimensions and your rear-seat setup before ordering.
