These bandanas are such lovely quality - the material is silky, and doesn't tug on my dog's soft puppy fur. I tried the Kathrine bundle in size Large for the summery colors, and my dog has gotten so many compliments on them already. My pup is still young (12 weeks, 24 pounds) but the bandana's arms are long enough that they should fit her for several more months. One minor comment is that the silky material can often come loose/undone unless the bandana is double-knotted and tied very tightly. Otherwise, they are awesome and I look forward to trying more from Remy+Roo in the future!
