Slinky Dog has always been the loyal, stretchy sidekick in Toy Story, and turning your little ones into him is pure magic.

Watching them toddle together, joined by a coiled slinky, feels like playtime has come to life.

It’s the kind of costume that isn’t just about Halloween, it’s about making a memory you’ll laugh about for years.

Materials Needed

• 2 brown baby/toddler costumes or brown fabric onesies (size appropriate)
• 2 green felt pieces (6" × 6") for collars
• 2 pairs of felt dog ears (about 4" long each)
• 2 pairs of tan felt booties (to look like paws)
• 1 large plastic slinky (20-24" long when stretched lightly)
• Hot glue gun and glue sticks
• Elastic bands (½" wide)
• Brown felt (½ yard) for body covers if you’re making DIY tunics

Step-by-step Guide

Step 1: Dress both children in brown onesies or tunics to create the dog body. Then add tan felt booties to mimic paws.

Step 2: Attach green felt collars around their necklines with safety pins or fabric glue. This small touch helps them look instantly like Slinky Dog.

Step 3: Add floppy felt ears to their hoods or hats. You now secure with hot glue or sew them in place for durability.

Step 4: Take your plastic slinky and stretch it to a safe, comfortable length between the two kids.

Next, attach each end to the back of their costumes using elastic bands sewn or glued onto the fabric.

Step 5: Make sure the slinky isn’t stretched too tight, it should bounce playfully but not restrict movement.

Step 6: Let your little Slinky Dog duo waddle together, and prepare for all the awws you’ll hear!

Note:

This works best for siblings or friends close in age so they can walk comfortably side by side.

For extra detail, you could paint their faces with a dog nose and whiskers.
