How to put it together

1
Measure your Frenchie's chest circumference at the widest part and their neck girth to ensure a proper fit, as they often require a size up due to their broad build.
2
Select a lightweight, front-walking or cape-style costume that does not restrict their airway or cover their snout.
3
Introduce the costume slowly in a calm environment, letting your dog sniff the fabric and rewarding them with treats.
4
Gently slip your dog's front paws through the leg holes of the costume, ensuring there is no tight pulling across the shoulders.
5
Secure any neck fasteners loosely, making sure you can easily fit two fingers between the fabric and your dog's neck.
6
Monitor your dog closely for any signs of overheating, stress, or restricted movement, and remove the costume immediately if they seem uncomfortable.

Keep dress-up sessions short and carry water to prevent your dog from overheating, especially in warmer weather.
