Choosing the perfect fit can make or break the look — and your dog’s comfort. One of the biggest misconceptions is thinking that a “Small”, “Medium” or “Large” costume automatically fits dogs of that size. But dog clothing works differently.

⭐ Start With the Chest Measurement

The most accurate way to pick a size is by measuring your dog’s chest girth. This single step helps avoid returns and ensures a comfortable fit.

Many dog pawrents assume a “small dog” needs a small costume — but broad-chested breeds like French Bulldogs often need a larger size, while long-bodied breeds like Dachshunds may fall in between.

That’s why fitting for chest measurement works better than weight, breed, or guess work.

⭐ If Between Sizes, Choose the Larger One

Costumes won’t stretch much, so if your dog sits between two sizes, always size up. A slightly looser fit is far more comfortable than something too tight.

⭐ Breed-Shape Tips

• Frenchies: Broad chest → usually need a size up

• Dachshunds: Long-bodied, wide chest → size up for comfort

• Cavoodles: Toy vs Mini vary greatly → often between sizes

• Toy Breeds: Chihuahuas, Pom Poms, Shih Tzus → smaller chest fits

“I bought XL for my Lab because her chest is 83cm — and that measurement helped me pick the right size.”

From classic dog Christmas costumes to playful accessories, here are the themes trending this year.

Santa Dog Costumes 

Always a bestseller. 

These are perfect for Christmas Day walks, family portraits and matching human outfits.

Elf Dog Costume

Bright, fun and bursting with personality. Ideal for active or cheeky pups.

Dog Reindeer Antlers

If your pup hates full outfits, dog reindeer antlers or christmas dog antlers offer instant festive vibes with zero effort.

Lightweight + Aussie-Summer Friendly Dress Ups

Because Christmas in Australia is generally warm, many dog pawrents may prefer:

• Dog christmas accessories

• Bandanas - Can be used for cooling.

• Dog christmas dress up styles that strap around the chest only

No one wants their pup freezing in fear, refusing to walk, or rolling around trying to escape the outfit. These steps help your dog feel confident and relaxed.

⭐ Step 1: Let Them Sniff First

Introduce the costume slowly. Let your dog:

• Sniff the fabric

• See it near their toys

• Associate it with treats

⭐ Step 2: Keep Try-Ons Short

Start with 20–30 seconds. Reward. Remove. Repeat later.
This teaches your dog that wearing the outfit leads to GOOD things.

⭐ Step 3: Use Distractions

Lick mats and yummy treats work wonders while strapping the outfit on.

⭐ Step 4: Choose comfortable dog costumes

If your pup struggles with full outfits, choose:

• Bandanas

• Headpieces

• Lightweight Costumes

• Simple dog christmas outfit accessories

⭐ Step 5: Avoid Forcing It

If your dog truly wants out, swap the outfit for a festive bandana — still cute for photos and more comfortable.

Dress them in comfort. Keep it festive. And let your gorgeous dog steal the Christmas spotlight.
