Using this pet jumper is easy. Just slip it over your pet's head and adjust it to fit comfortably. Make sure not to pull it too tight around the neck. When it comes to maintenance, you can machine wash it in cold water on a gentle cycle. Avoid using bleach as it may damage the white skull design. Hang it to dry instead of using a dryer to keep its shape. Also, check the size chart before purchasing to ensure the best fit for your pet.
