Ruffwear harnesses were recommended to me by the rescue organization, the Sato Project. Since then, I've used Ruffwear harnesses on 3 dogs (1 60 lb dog and 2 40 lb dogs). From active puppies to slower seniors, Ruffwear harnesses are safe and comfortable. The adjustable front range harness can grow with your dog and expand as they do. I would recommend Ruffwear Front Range® Dog Harnesses to any pup parents.
