Product & Specifications: Professional Design - Does your dog get anxious during thunderstorms, fireworks, or other loud noises? Wir have conducted extensive experiments to develop these noise-cancelling headphones specifically designed for dogs, which can protect your furry friend from the effects of noise. Why Use Earmuffs for Dogs? - The structure of a dog's ear is very different from that of a human's. While humans can hear sound frequencies between 20Hz and 20,000Hz, dogs can hear frequencies between 15Hz and 50,000Hz, a much broader range. Therefore, dogs are much more sensitive to noise than humans. Protecting your dog's ears is more important than you may realize. Relieve Pet Anxiety - Does your dog sometimes get overly excited and then appear lethargic? This may be caused by noise. Our dog earmuffs are made of high-density soundproof cotton, and the adjustable elastic band has a wide range of adjustments. The part that contacts your dog's body is made of soft materials, ensuring your dog can wear it comfortably. 2 Different Colors and Adjustable - Our dog earmuffs come in 2 stylish colors: and Adjustable, Head Circumference of 17 to 24 inches. The earmuffs have space to fold your dog's long ears, but if their ears are too long, you can leave some of them outside and tighten the elastic band to achieve optimal noise-cancelling effects.
