How to put it together
- 1
Measure your dog's neck circumference and back length to ensure you select the correct cape size.
- 2
Secure the red cape around your dog's neck using the built-in hook-and-loop fastener, ensuring it is snug but comfortable.
- 3
Adjust the cape so the yellow and red 'S' shield sits centered on your dog's back and does not drag on the ground.
- 4
Slip the gold collar onto your dog's neck, making sure you can easily fit two fingers underneath for safety.
- 5
Attach the circular gold dog tag to the collar's D-ring so it hangs visibly at the front.
- 6
Give your dog a treat and let them walk around indoors to get used to the feel of the cape before going outside.
Makeup & hair
Keep your dog's natural coat clean and brushed. No makeup, hair dye, or styling products are needed for this classic canine look.
