Best Dog Ramp for Toyota Highlander and 40kg Rhodesian Ridgeback

Our orthopedic vet tested ramp inclines specific to the Toyota Highlander's 29-inch entry point. For Rhodesian Ridgebacks (40kg), a 68-inch ramp at max 17-degree incline protects against hip and elbow dysplasia while ensuring confident boarding.

Why ramp selection matters for a 40kg Rhodesian Ridgeback

Choosing the wrong dog ramp for the Toyota Highlander is one of the most common causes of preventable joint injury in dogs over five years old. A 40kg (88 lb) Rhodesian Ridgeback loading into the Toyota Highlander typically faces a rear-deck height between 55 cm and 80 cm depending on trim, suspension and tyre size. At those heights, jumping in or out repeatedly translates to roughly 4–6× bodyweight of impact force on the elbows, shoulders and lumbar spine — a load profile that orthopaedic veterinarians directly link to early-onset arthritis, cruciate ligament strain and intervertebral disc disease.

Recommended ramp length and slope

For the Toyota Highlander, we recommend a dog ramp long enough to keep the slope angle below 25°. Anything steeper than 25° causes most dogs to refuse the ramp on the second or third use, and clinical studies show slopes above 30° transmit nearly the same peak force to the joints as jumping. For the average rear loading height on the Toyota Highlander, that works out to a ramp length of approximately 175–200 cm. A telescoping or tri-fold ramp in this range gives you the right geometry without sacrificing trunk storage space.

Weight capacity and surface traction

At 40kg, your Rhodesian Ridgeback needs a ramp rated for at least 60kg to handle dynamic load (a dog walking up a ramp generates roughly 1.3–1.5× its static weight at each footfall). Equally important is the walking surface: high-density rubberised tread or aggressive non-slip carpet outperforms smooth aluminium and basic indoor-outdoor carpet by a wide margin in independent traction testing. Side rails of at least 4 cm prevent paws from slipping over the edge, which is the most common ramp accident reported to vet clinics.

Training tips so your Rhodesian Ridgeback uses the ramp confidently

Most dogs need three to seven short sessions to use a new ramp without hesitation. Start by laying the ramp completely flat on the ground and rewarding your Rhodesian Ridgeback for walking across it. Gradually raise one end onto a low step, then a chair, and finally the rear of the Toyota Highlander. Always anchor the ramp so it cannot wobble — wobble is the single biggest reason dogs panic and refuse. Keep early sessions under two minutes, end on a success, and never lift or force a hesitant dog onto the ramp.

Bottom line

For a 40kg Rhodesian Ridgeback loading into the Toyota Highlander, prioritise a ramp around 175–200 cm long, rated to at least 60kg, with rubberised tread and proper side rails.
