I'm selling these because my dog didn't like trying them on. They fit my 2.5kg Maltese perfectly. I bought a different size because my dog's front paws are a bit large. The surface of the shoes is mesh, making them lightweight and breathable. They have two buckles, so they fit securely and won't come off even when running. - - Color: Black - Sizes: 35, 40 - Type: Dog shoes - Features: Securely fastened with two straps Thank you for looking.
