Rear support or full support?

Four questions about how your dog actually moves, and a straight answer at the end. Most owners need a rear cart. Some do not.

Question 1

Can your dog hold their own weight on their front legs?

Watch on a floor with grip, over a couple of days rather than one moment. A dog who slips on tile will look worse than they are.

Question 2

Can they push themselves up from lying down?

Using the front legs to lift the chest, even if the back end needs help.

Question 3

Where is the weakness?

If you are unsure, this is the question worth asking your vet before buying anything.

Question 4

Is the condition expected to progress?

Ask your vet if you do not know. It changes whether a convertible frame is worth the extra.

Based on your answers

A rear support cart

Two wheels, carrying the back end, with your dog's front legs doing the walking and steering. This is what most owners need, it is lighter, it turns more easily, and dogs learn it faster.

  • Lighter frame, so less for a tired dog to push
  • Turns in a hallway, which a four wheel frame often will not
  • Most dogs are moving confidently within a few days
  • Many models take a front attachment later if things change

A full support cart

Four wheels, carrying both ends. It is heavier and needs more room to turn, and it exists because some dogs genuinely cannot carry themselves at the front either.

  • Supports the chest as well as the hind quarters
  • The right answer when the front legs are failing too
  • Needs more space and more patience to learn
  • Worth discussing with your vet or rehab professional first
This is equipment guidance, not a diagnosis. If your dog's movement has changed suddenly, or they seem to be in pain, speak to your vet before ordering anything.

Side by side

The honest comparison.

Including the parts that are less convenient, because a cart your dog will not use is not a saving.

Still not sure?

Send a short video of your dog walking on a non slip floor, side on, and a note on what has changed. We will tell you which type we would be looking at, and say so if the honest answer is neither yet.
