DIY Construction Worker Dog Costume - Rafferty's 31 Days of Dog Costumes for big dogs -

Rafferty’s DIY construction worker dog costume is adorable and so easy to put together with just two items. With many size options on the market, his costume will work for even the biggest of dogs!


Let’s get to work!


Construction Worker Dog Costume Supplies


Safety Vest

Safety first! Safety vests come in lots of colors and designs. Find one that works best for your dog. This one is a good option.


Hard Hat

Every construction worker must have a hard hat! For our dog costume, the smaller the hat, the better. Try this toddler hat.


Even with a small hard hat, you’ll likely need to secure it to your dog’s head. Try using hot glue to attach the hat to a headband.



You can stop with just a vest and hard hat, or you can add more accessories to take this dog costume to the next level.

Toy Tools

Some toy tools will really add to this costume. Hang a hammer or saw around your dog’s neck for more authenticity. This set of toy tools would work well.


Dump Truck

If you’re really committed to this costume, and your dog is ok with it, you can get this remote-controlled kids ride-on dump truck construction vehicle. Have your dog ride in it or just walk beside it, and you’ll be sure to turn heads!

Our construction worker dog costume is part of Rafferty’s 31 Days of Dog Costumes, costumes that you can DIY, designed for big dogs. Find more dog costume ideas here.

PS: As always, please be sure to put the safety and comfort of your dog first. Ensure the clothing isn’t too tight or binding. Dogs can overheat quickly, so if the weather is too warm, don’t dress up your dog. And watch your pup for signs of stress. Some dogs will make it obvious if they hate the costume, but others might give more subtle clues like yawning, panting and pinned back ears. Remember, a funny Instagram photo isn’t worth making your dog miserable, or worse.
