The 15 Most ADORABLE Pet Halloween Costumes on Instagram

Happy Halloween! Now that the year's biggest costuming day is officially upon us, we're busy finalising spooky plans, putting together our last-minute outfits, and stalking Instagram to see what everyone else is wearing. But when we started scrolling through our feed, you can imagine our shock and awe when it wasn't the human costumes we ended up squealing about, but those donned by our furry little friends.

From Tuna the chihuahua to Biddy the hedgehog, these little guys in their best Halloween garb is the stuff pet dreams are made of. (See what we did there?)

If you're in the mood for a full-on cutefest, keep scrolling to enjoy these photos as much as we did!
