The Ruffwear Front Range Harnesses are well designed, well made and tough enough that I never
ever have to worry about my dogs managing to get loose. Solid hardware and in a nice variety of colors too.
Once you get a handle on adjusting the straps to snuggly fit your pup for comfort and decide if you'd like your dog's leash attached to the back or front of the harness, nice to have options, you are good to go!
I highly recommended the Ruffwear Front Range Harness. Four paws up!!
