This is a set of Dr. Pettle's S-size harness and leash. - Brand: Dr. Pettle - Size: S - Color: Gray - Condition: Used Thank you for viewing. I bought this because I was attracted to the fact that it puts less strain on dogs, but unfortunately, it didn't fit my dog's neck, so I'm selling it. I've used it about 10 times, and since it's a puppy, there are some bite marks, so it shows signs of use. Please understand this before purchasing. Thank you very much.
