Step 1: You Will Need

Here is what you'll need to create this hilarious doggie costume!

  • 2 1/2 yards of furry brown material
  • 16 pieces of black felt (8X10)
  • Large dog harness (I found mine used for 5 dollars)
  • 9 plastic garbage bags
  • Large bag of material filling/stuffing
  • Scissors
  • Strong craft wire
  • Wire cutters
  • Needle nose pliers
  • Hot glue gun/glue sticks

Step 2: Make the Abdomin

Stuff one of the plastic bags, until it is full. Close it with hot glue. Cut out a circle of fabric, and glue it over and around the stuffed bag. Set aside.

Step 3: Make Legs

Make each leg, 8 total using the following steps:

  • Cut 8 pieces of wire three feet in length
  • Stuff a plastic bag 1/3 of the way full
  • Glue shut
  • Add fur to the bag
  • Stick the wire through the bag leaving 4 inches at the top
  • Fill one sheet of black felt with a small amount of stuffing, forming a tube. Secure tube with glue.
  • Feed that tube throguh the wire, below the furry part, and secure with hot glue
  • Add a 4 inch strip of fur below the black felt
  • Add another piece of black felt below that (no stuffing in this one)
  • Repeat process 8 times

Step 4: Cover Harness in Fur

Cut a piece of fur to the outline of the harness. Hot glue fur to the harness, covering it completely.

Step 5: Add Legs to Harness

One by one, feed the top 4 inches of wire through the harness, space apart like spider legs.

  • The wire is sharp enough to poke through, without a hole being pre-cut.
  • Feed wire through
  • Use needle nose pliers to twist wire to secure it
  • Then stick wire into the leg, and sucure the leg to the harness with hot glue
  • You want the wire to be hidden in the leg, so that is can't touch your dog
  • Comfort and Safety for your animal above all!!!!

Step 6: Add Abdomin

When all the legs are attached, add the abdomen!

I used only hot glue, but you could stitch it with fishing line for added strength if you wish.

Step 7: Be a Big Hit!

We went as a Family Circus, and our Giant Spider was the hit of the party! And trick or treating was an absolute scream! Nothing like seeing a 100 lb Spider running down the street on All Hallows Eve! Have a blast this Halloween including your furry family member on all the fun!

    I can honestly say that he loved it! It was comfy, and he has a blast! But not all dogs would like being dressed up for sure. You just need to know your pet.
