I live in the city. With two medium sized dogs, that became obsessed "competitively" with sniffing pee and marking territory. Their previous leads were long enough to allow them to dart back and forth, under my feet at times, sniffing everything. Tired of being frustrated by this behaviour, I knew I needed to put them on a short leash. Literally! It was almost instant the improvement in their behaviour. The leads let me keep their heads up and focus on our walk. I have a few other products from RUFFWEAR, lasting for years now. The quality, and durability make them forever products.
