Usually, dog ramps are made of aluminium or plastic. Both materials are lightweight and easy to fold and unfold. However, the ramp should be sturdy enough to endure the weight of your pet, which is why you should check the materials first and see if they’ll work for your dog. If you have a smaller dog breed or a puppy, it’s good to invest in a plastic ramp. For larger and heavier dogs aluminium is a better choice. Heavy-duty ramps are a better choice if you’re going to use the ramp frequently. https://lifestyletrendsofaustralia.wordpress.com/2023/04/18/folding-dog-ramps-buying-guide/
