Our large ramp is designed for the couch or for the bed (please check the heights of the large v the highset ramp to see which size ramp would be better suited to your needs). We also recommend our large ramp to anyone who has more than one dog, or has a Frenchie or Bulldog for example. There is also the option to strengthen these ramps so that they can be used by larger dogs (if you require this please contact us directly to discuss). The length of the ramp is 1m long and 32cm wide.The ramp has 3 heights: 40cm, 45cm and 50cm. All our ramps can lay flat for easy storage. All our ramps are made with high grade marine carpet to prevent slippage and give your dog the best grip when going up and down the ramp.
