★The first photo is from the online shop listing. There is no instruction manual. --------------------------------------------------- Thank you for viewing. This is a harness for medium to large dogs. I used it for morning and evening walks for a full year. I am selling it because I bought a new one. There are no major tears, but there are some areas that are rubbed due to the nylon material, and there is hair on the Velcro parts, but the adhesive strength is still good. The buckle parts are not broken and fasten securely. The manufacturer recommends using it for 6 months to 1 year. Hand-washed. 【Manufacturer's Description】 Ideal for medium and large dogs that tend to pull. This harness reduces the burden with its balancer. Made of soft material, so it's gentle on your dog. ■Target: Neck circumference 420mm～540mm, Chest circumference 600mm～760mm, Large dogs up to 30kg in weight ■Product size: Width 250mm x Depth 90mm x Height 260mm ■Material: Nylon Harness Dog harness Large dog Medium dog
