Ultra-lightweight and breathable purple harness, size 1, recyclable packaging. - Brand: coralpina - Size: 1 (chest 33cm / 13in) - Features: Ultra-lightweight, breathable, reflective material - Color: Purple - Packaging: Recyclable Thank you for looking. I only tried it on after purchase. I was looking for a harness that wouldn't put a strain on my dog's neck after he developed a neck hernia, and I found this one. I bought it based on the size, but it was a little tight on my Chihuahua (3kg), so I think it would be a good size for puppies or dogs in the 2kg range.
