Back in 2019, I had purchased a leash made by Ruffwear and Franklin (my sweet fur child) had managed to get loose from it a few times. Obviously that’s not something any pet parent wants to happen with their leash; I contacted Ruffwear and they handled it SO well and then sent me the Knot-a-Leash as a replacement at zero cost to me. After 4 years, I just got a second one for cleaner/dressed up endeavors but the original is still working!
