Our Dog Helmets For Small Medium Dogs are designed with ventilation and cooling in mind. The streamlined design features 14 air vents, which help to reduce wind drag and increase airflow. This keeps your pet cool and breathable, even during hot summer rides. The helmet is pet-friendly, with a high-density EPS foam interior. This lightweight material adds no extra pressure to your pet's head and effectively minimizes the risk of head injuries in case of accidents. Comfort and adjustability are key features of our helmet. It has quick release buckles with one-touch control, making it easy to put on and take off. The soft detachable sponge mat inside ensures long-lasting comfort, even during extended wear. Not only is our helmet functional, but it also has a cool look and adds a touch of fashion to your pet's outdoor activities. It is perfect for motorcycling, biking, and walking. Just like you put on your motorcycle helmet, don't forget to help your pets put on theirs. To ensure the correct fit, please measure the circumference of your dog's head with a fabric tape measure.
