Adjustable and Comfortable Design: Features a 5 cm adjustable leather strap, ensuring a perfect fit for pets of all sizes. Harness the Power of Nature: The friction between fur and amber releases aromatic terpenes that naturally repel fleas and ticks, while static electricity prevents parasites from clinging to fur. Stylish and Functional Gift for Pet Lovers: These necklaces look adorable on dogs and cats, making them a thoughtful and practical gift for any pet owner. Certified Authentic Baltic Amber: All products in our store are made with real Baltic amber and are certified for guaranteed authenticity. How to choose size?To ensure a proper fit, measure your dog's top neck by gently wrapping a soft tape measure around it, leaving enough room for two fingers to fit comfortably. The collar includes an amber chain and a 2 inch leather extension, with the measurement ranging from 8-10 inch, with 8 inch being the amber chain and 2 inch being the leather extension. *Please note that the color of your amber collar may vary slightly from the photo, as each piece of amber is unique.
