Size Information
Exact product dimensions: 52 in (length) × 25 in (width). Hard-bottom insert provides firm, even support across the full area.
Best for: Provides full coverage for most truck rear openings and many SUVs. Ideal for medium to large dogs (examples: Labrador, Golden Retriever, Boxer) and a comfortable platform for dogs that like to stretch out. As a general guide, this size is suitable for dogs up to about ~80 lbs depending on how they lie down.
How to confirm this fits your vehicle and dog:
- Measure the flat area you want to cover in your vehicle: available length (side-to-side) should be at least 52 in and available depth (front-to-back) should be at least 25 in.
- Measure your dog from the tip of the nose to the base of the tail (or from chest to rump); if that length is less than 52 in your dog can lie fully stretched out. For dogs that curl, allow extra room for comfort.
- If your vehicle’s rear opening is narrower than 52 in, the extender will not cover the full span — it still may work as partial coverage but won’t provide full platform support.
Quick check: If your truck or SUV rear seat area measures at least 52 in × 25 in, this extender will fit and provide a firm, waterproof surface for medium-to-large dogs. Removeable cover makes cleaning simple.
