Hi everyone. I am looking to take my Vizsla out backpacking. We own a Ruffwear Approach backpack. It is a fine product. well constructed. the problem is the nylon straps. the coarse material is murder on her skin. Has anyone found a solution? I hired a seamstress to relocate the straps. She even built removable fleece sleeves to cover the abrasive straps at the contact points, and still we come home with nasty welts. I have been unable to ever use a nylon harness for this same reason. What am I missing? Im desperate to find a solution. thank you in advance!
