How to Choose

Pet Loader, pet steps are available is several different models. To help you choose the Pet Loader that will best suit you, consider the appropriate size for your dog, vehicle and use. The following information will help you with that choice in more detail.


Our pet stair models differ primarily in platform (step) material and width of the platform. Our Pet Loader Mini and Pet Loader Ultra Light Aluminum dog stair models are lighter and easier to handle. Pet Loader Light and XL have rugged plastic platforms, which are more rugged, and weigh more, these pet stair models are designed for the larger breeds.

Extension Height

Besides platform material, choose the number of steps 3, 4 or 5, that is right for for the height of your vehicle. Measure vehicle from the pavement to where your pet will enter the vehicle such as the cargo floor, seat, truck bed, etc. then see our height chart below. Keep in mind the opening width, especially for passenger door openings, as they tend to be more narrow.

Measuring for a Pet Ramp

Choosing a Loader Based on Dog Breed or Size

Many customers want to know which Pet Loader model is suited best by the dog breed or size. Here are some guidelines to help.

For small dogs, such as the toy breeds, Chihuahuas, Shih Tzu, Toy Poodles, Pugs, Pomeranians, and Maltese, the Pet Loader Mini works perfectly. The smaller platform of the Pet Loader Mini dog stairs will work for them in almost every situation.

For medium to large dogs, we recommend the Pet Loader Ultra Light or Pet Loader Light. The 16″ platform of the Pet Loader light will accommodate almost every breed, Labrador Retrievers, German Shepherds, Golden Retrievers, Bulldogs, Pointers, and Huskies. These breeds typically weight less than 150 pounds. For those that are over 150 pounds we recommend the Pet Loader XL.

For extra large dogs, referred to as the Great Breeds, we recommend the Pet Loader XL. These dogs include Mastiffs, Great Danes, Newfoundlands, Bernese Mountain Dogs, and Saint Bernards. These dogs because of their size and weight should be using the Pet Loader XL pet stairs, with its 18″ platform. All dogs that weigh over 150 pounds or that are built with a wider girth should use the wider, more rugged Pet Loader XL.

For other pets, if you have another pet in mind to use our pet stairs, keep our maximum weight allowances in mind. Pet Loader, pet stairs are made for pets only and not for human use.
