This is a sled I created several years ago to run our dogs. I have deconstructed the dog sled and put it back together to create an instructable for the Snow Contest. Please vote in the contest.

I have made three of these dog sleds from stuff I was going to trash. Build time is 30-60 minutes. The sleds are featherweight, durable and will provide hours of fun..

Step 1: Alpha and Beta Sleds

On the first one I faced the chair forward and hitched up Daisy, our very fast dog. I think she might be a Lurcher or a cull from a sled dog breeder. My kids, the crash test dummies, called it the death sled after trying it out while sitting in the chair. They were laughing and screaming so hard they wouldn’t have felt a thing. You could add another spreader bar/ footstand in to allow for a safety driver in the rear.

I turned the chair around on the next two and found that offers much more control. You can hold the arms to stand on the spreader bar and sit on your knees up on the chair once you're cruising.

Step 2: Tools and Materials

Materials:
1 old plastic lawn chair
1 pair old skis
1x2” or 1x4” piece of wood 24" long

Hardware:
6ea. - #10 x 2” machine screws,
8ea.washers,
6ea. - #10 nuts,
2ea. – 1.5” drywall screws

I quickly built the 1st chair just using drywall screws but they eventually broke and/or loosened.

Tools:
Drill driver
3/8” drill bit
5/32” drill bit
Phillips head screwdriver
3/8” deep socket or wrench (or 3/8” wrench or nut driver)
Hot glue gun
Tape measure

Step 3: Bolt the Chair to the Skis

Line up the skis evenly, eyeball the center of gravity and position the chair on top of the skis in a comfortable position, center the legs on the skis. (I positioned the chair backwards so the sled driver can hold onto the arms of the chair)

Use a piece of 1x2” or 1x4” as a spreader bar/ footstand for the front chair legs as they are wider than the back ones.

Bolt the chair to the skis.

Step 4: Construction

Use 5/32” bit to drill through each rear leg of the chair and partially into the ski
Remove the chair and finish drilling the holes through the skis
Turn the skis over and use the 3/8” bit to drill a countersink hole for the head of each bolt.
Run a machine screw through the hole, making sure it doesn’t protrude. If it does, countersink a little deeper. You will seal the holes later with hot glue.
Place the chair onto these screws. This will help align everything square.

Measure the distance between the inner edges of the skis where the legs are attached.
Align the skis parallel (using the measurement you just took) beneath the other chair legs.

Drill a hole through the wooden spreader partially into the skis. Center the holes.
Remove chair and drill the rear holes just like you did the front holes.

Use two more machine screws, washers and nuts to secure the wooden spreader bar.
Attach washers and nuts and tighten down everything with wrench

Place the chair back onto the screws once again, add washers & nuts and hand tighten snug.

Drill 5/32" holes through the chair legs and the wooden footstand/spreader bar.
Insert machine screws with washers through these holes, add other washers, nuts and tighten everything down with the 3/8" wrench.

I used drywall screws to attach another 1x2” for a bigger footstand/spreader bar. If you use a 1x4” you won’t need this piece.

Step 5: Attach a Lead Rope

Turn the sled over and use a hot glue gun to fill in the countersunk holes. Cut off excess smooth with a razor blade.

Tie a rope through the slats on the back of the chair to attach a lead.

Step 6: Mush!

For a lead I used a skijoring lead which is just a poly rope with a bungie cord through it.

Attach your best canine friend and let her take you for a ride.

Give it a try. It is best to help the dog get running a bit by standing on the spreader bar and kicking. Use Fred Flintstone braking techniques to steer and stop. Once you get going it is a really fun ride.
