Getting Started – IMPORTANT TIPS

We created the Walkin’ Wheels dog wheelchair in the hope that you will adjust the cart, put it on your dog, and in a few moments watch him or her running and playing again. It can happen that way, but doesn’t always. A wheelchair, though, can be a major adjustment for a dog. On the one hand, the frustration of painfully dragging an immobile back end is suddenly gone. Freedom! On the other, there’s a strange device following the dog around, sometimes making odd noises and getting caught on furniture and doorways.

  • Be calm, quiet, and slow when putting on the cart for the first time. Lots of stroking and reassurance is needed here. Treats help, too.
  • Let the dog get used to the harnesses before attaching it to the cart. It may take a few minutes or a few hours for him or her to get used to the harnesses.
  • Keep in control of the dog’s movement at first. When the dog takes his first step in the wheelchair it will not only feel unfamiliar, but it may also make a clicking sound. In some cases, if the dog is startled, he’ll move quickly and the mysterious sound will follow. This can be very disturbing to an animal (or a person, for that matter). We recommend that you hold him while he begins to move. If the dog does ‘freak out’ then disconnect the harness from the cart immediately and try again later.
  • Keep the dog in a clear area at first and keep him on a short leash. If you are going to use the cart indoors, be prepared for some scraping and scratching damage on walls, door frames, table legs and more.
  • Limit his time in the cart. Until your dog gets used to the Walkin’ Wheels dog wheelchair, limit the amount of time spent in it. Try limiting cart time to 10 minutes each session until he or she feels comfortable. The dog should not stay in the cart all day. The Walkin’ Wheels dog wheelchair is designed to allow your dog to get exercise and physical therapy.
  • If the dog moves backwards when you put him in the cart, this is normal – the dog is simply trying to sit down. Make sure the leg rings or rear harness is holding the back end of the dog up high. If he does not move at all, check for harness comfort and encourage him with treats.

After you’ve had a chance to use it, please fill in the survey at It helps us improve the Walkin’ Wheels dog wheelchair.

After the first few uses, check for chafing or sores from the harness.

  • Watch the “Fitting your dog” video. It has some important tips on how to put on and adjust the cart, The Video can be found on the web at .

Step – By – Step

These step-by-step instructions each have corresponding chapters in this manual.

  1. Unpack Cart. Insert wheels and side rails. The notches on the knuckles are on top of the cart. (see Figure 1). The silver-color side rails and leg struts are inserted in the blue frame. Use the snap-buttons to snap it into place. See “Adjusting the size with snap buttons,”
  2. Adjust the cart to the approximate measurements of the dog. See the section on measuring your pet.
  3. Put the Front Harness on the dog. Red Strap goes on the bottom, Base of the “T” shaped neoprene faces forward. Adjust the front harness as needed. Each of the straps have a neoprene & Velcro comfort sleeve which can be cut, if needed, and wrapped around the strap.

There are alternate methods, changing the order of 4,5,6 to suit your dog.

  1. Attach the Leg Rings to the Cart or Put the (optional) Rear Harness on the dog.
  2. Put the rear legs in the leg rings or ttach the (optional) Rear Harness to the cart.
  3. Attach the Front Harness (with the dog in it) to the cart.
  4. Make any necessary final adjustments.
  5. Install the Allen-wrench set screws to reduce rattling noise (optional).
  6. Allow the dog to get used to the cart with short trips in the cart. Stay with the dog at all times, preferably on a leash. Some dogs adapt quickly, others take time

Adjusting the Cart

Opening/Locking the Legs – Folding Flat

The black plastic pieces that connect the legs to the frame are called “knuckles” (see figure 1). Dials on the side knuckles (called “Dial Caps”) can be turned to loosen the legs and allow them to open and close.

To open the legs, turn the dial caps so that the teeth on the inside of the knuckle separate and you can move the leg freely.

Do not unscrew the dial cap all the way off, although if you do, just push down a little to compress the spring inside, and screw the dial cap back on.

There are raised markers on the top of the knuckle and the top of the leg; One on the cart-side of the knuckle and two on the leg-side. Line up the raised marks so that the mark on the cart is between the marks on the leg. See Figure 4. In the case of active dogs, you can angle the wheels back further. This is discussed in the section titled “How to tell if the Cart is Adjusted Properly.”

Opening the cart

Adjusting the size with snap buttons.

Note: Make sure the set-screws (figure 4) are loosened or removed before adjusting.

This is called a SNAP BUTTON. Push it in with your fingertip to change the size. Note that, in some cases, the snap button will be behind the knuckle and your fingertip won’t fit. In this case, use the back end of a pen, or any thin, blunt object to release i

Figure 2 – Snap Button Adjustment

Figure 3 – Snap Button behind the knuckle

Snap buttons are used to adjust the height, length, and width of the cart. Optional: Once the cart is adjusted properly, use the included Allen wrench and to insert and tighten the set-screws. There are six set-screw holes on the cart. Although they are not necessary for sturdiness, they keep the cart from rattling.

Set Screw

In some cases, we have included an extra set of siderails and back connector. This is in case you need additional width or length. If these were not included in your purchase, they can be purchased separately on our website.

Width and Length Extenders

Some carts are shipped with both long and short width and length extenders. If your shipment did not include these additional parts then they were not needed according to your measurements. They may, though, be ordered separately.

1 – Short (6 inch) Width Connector snaps into the back of the wheelchair for dogs less than 9 ½” wide. For width measurement, see measurement “C” on the following measurement chart.

2 – Short (15 inch) Length Extenders snap in the sides of the wheelchair for dogs less than 19″ in length. For length measurement, see measurement “A” on the following measurement chart.

3 – Long (9 inch) Width Connector snaps into the back of the cart for dogs greater than 9 ½ inches wide.

4 – Long (26 inch) Length Extenders snap into the sides of the cart for dogs greater than 18″ long.

Sizing the Cart

Adjusting the Length.

Insert the length extenders into the cart frame. The black end-cap of the length extender is in the front. The front harness clip is on the outside.

Push the snap button in to allow the length extender to slide into the cart frame. You’ll need to depress the snap button at each hole. When the snap button is behind the black knuckle, use the back of a ball-point pen or the included Allen wrench to reach the snap button.

Adding Stability

Later, when the all of the silver pieces are adjusted to the correct length, you’ll tighten up the cart using the Allen wrench and two set screws. The set screws are not necessary for stability; they just keep the cart from rattling.

Adjusting the width

Use the snap buttons on the width connector to adjust the cart to the proper width. There should be about ½ inch of space on either side of the dog at the black plastic knuckle.

The width extender shown below is the ‘small’ extender shown at its smallest position. The larger width extender does not allow the cart to close all the way.

Width Extender

Adjusting the height

Height is determined by the size of the wheel or tire on the strut, (there are different sizes). Depending on your order, you may have received 4″, 8″, 12″ or 16″ wheels attached to 6″, 9″, 12″, or 15″ struts.

The cart is shipped flat. Open up the leg by turning the black knuckle counter clockwise, so that the two notches are in the middle of other notch.

Slide the strut with the wheel into the leg slot with the wheel facing outwards. Dog’s legs should be just touching the floor. Your dog can use both legs to develop muscle.  If rear legs are weak or paralyzed, you will want to put the feet into the stirrups so they are not dragging on the ground.

Optional – Lock in the strut wheel with the provided set screws using the Allen key.  Screw locations are found at the ends of the frame next to push button.

Hold the front harness with the one padded strap aligned with the front of the animal and one padded strap aligned with the top of the animal.  The buckle clips on the side should be pointed back. Neoprene shield (the base of the “T” shape) should point forward.

Unbuckle bottom strap and fit remaining loop around the pet’s head.

Re-buckle the bottom strap (RED) around the animal’s chest, in back of the animal’s front legs.

Tighten straps to fit snugly on animal so that the inside padding is aligned with the pet’s shoulders.

Rear Support: Leg Rings or the Rear Harness

Two types or rear harnessing systems are available; the Leg Rings and the Rear Harness.

Leg Rings

To install the leg rings, simply clip the plastic connectors onto the cart. Adjust the straps so that the leg rings are tight to make a secure seat for the dog. The leg rings should not hang down much. When the dog is in the leg rings, the knuckle should be at the mid-hip level. See the section on fitting the dog later in this manual.

The rubber tubing can be shortened if necessary with scissors. Avoid cutting the strap inside.  Make sure that the dog is able to pee and poop freely.


The Velcro wrapper can be moved forward or back to avoid putting pressure on the dog’s genitals. In addition, the Velcro can be wrapped loosely so that there is a space between the rings. Adjust for best comfort and fit

The leg rings that come with your Walkin’ Wheels work great used as a lifting harness. The excess strapping can be Velco together to make handles on each side.



To avoid having to lift the dog you may clip the back clip on first, move the dog into place, bring the front of the straps through the dog’s legs and clip.

The Lifting handles can be attached to the harness clips for help lifting the dog when not in the cart. Use one or both handles based on your comfort and the comfort of the dog.

Clip-On Leg Ring Support System

It’s easier than ever to get your dog in and out of the Walkin’ Wheels dog wheelchair with our clip-on leg ring support system. With these, the leg rings clip on to the dog, then the dog’s back end can be attached to the cart with minimal, or no lifting at all.

Rear Harness:

To attach the Rear Harness to the animal, put the rear harness on the floor.

Put the animal’s rear legs through the leg-holes. There is no Front or Back to the harness. Reinforcement strapping is on the bottom side.

Pull up the harness like a pair of shorts and clip the back-strap(s) to hold the harness on the dog. Back straps may be crossed.

The four plastic clips hanging at the side are for attaching the harness to the cart. They can also be used to attach the optional lifting straps.

Un-clip the cart clip

Position the animal with its hips lined up to the plastic knuckle section of the cart.

Loop the harness clip over the cart frame and lock it into the peg.

Customizing the harness for comfort and elimination

The harness is made of Neoprene so that it can be safely cut with scissors to avoid the animal’s genitals allowing them to pee and poop when in the cart. It will not fray at the edges. Remove the harness from the dog before cutting it, and make sure not to cut the reinforcement strap material.

Cutting Excess Strap

Note that the straps can be cut if there is excess. After cutting, you can seal the end of the strap by briefly touching it with the flame of a lighter. This will melt the end and keep it from fraying.

Attaching foot straps (Stirrups)

If feet are dragging or knuckling under, use stirrups.

Place the animal’s hind legs in the foot straps so that the foot rests about 2 inches above the ground and tighten to a snug fit.

Belly Strap (Optional)

Some animals will need additional support under their belly. You can tell if they need additional support if the dog’s spine bows downward, or if dog is elderly or overweight. See the illustration in Figure 9, 10 and 11.

To put the belly strap on the cart you can either (photos below).

a)    place the siderail through the looped opening in the strap or

b)    undo the tri-clip and loop the strap over the siderail, then feed the strap back through the clip

The purpose of the rope is to prevent the belly strap from sliding backwards toward the rear of the dog.

If your Belly Belt is equipped with Velcro (Photo to Left) on one side, loop the strap over the railing and attach the Velcro under the dog’s belly. A rubber band can be used to secure excess strap if needed.

The belly strap is looped around the side rail from the inside, through the rope, then back through the clip. The rope looped around the front clip and is used to prevent the belly strap from sliding backwards underneath the dog. Cut and tie it if desired.

How to tell if the Cart is Adjusted Properly

When the cart is adjusted properly, the animal stands in a ‘natural’ position. Here’s what to check. Refer to the figure below.

A – Knuckle at the hips. If you were to draw an imaginary line from one knuckle to the other, the line would pass right through the dog’s hips… where the bone of the leg meets the bones of the body. If not, tighten harness and/or adjust length. Allow 1″ on each side between dog and black knuckle.

B – Front Support loop at the shoulder. The loop on the front harness that the bar goes through should be at the shoulder. Adjust the straps so that the loop is held firmly against the shoulder. Then clip into cart.

C – The dogs back needs to be straight or arched UP (slight hunch). In this photo the dog’s back is arched down a little. This is NOT correct and this dog needs the Belly Strap.

D – The back legs need to be just touching, or just off the ground, depending on the health of the back legs. If the dog wants to use his back legs, then allow his feet to touch lightly. This is often adjusted by tightening the straps that hold the harness to the frame – this brings the dog’s seat up. (Take the dog out of the harness before adjusting.) If the height of the harness cannot be changed, then lengthen the leg struts.  Consider boots if the feet drag. Use the stirrups if the dog cannot use his back legs or the feet are dragging on the ground.

E – The horizontal bar needs to be level.

For active dogs with strong front legs, the wheels can be adjusted to angle back.

Large Dog Modification

To accommodate very large dogs we make a small modification to the Walkin’ Wheels dog wheelchair that moves the animal forward in the cart.

This modification involves:\

1 – Moving the knuckle forward 2 inches

2 – Moving the front peg (to which the harness attaches) from the blue frame to the silver extender.

This moves the dog forward and spreads out the saddle for better support of larger dogs.

If you need to significantly adjust the silver extender for longer or shorter dogs, the front peg can be moved into one of the four holes provided in the silver extender. Use the special “Peg Sized” allen wrench provided.

If necessary, should you need to use the cart on a smaller dog, the peg can be put back into the smaller dog front peg position.
