Dog Extreme Police No. 1, 35–45 cm is a black nylon dog harness from the Police series by the Ukrainian company COLLAR. It's made of strong, hard-wearing nylon with a soft lining inside to prevent chafing on walks. The harness is adjustable, fastens with sturdy buckles that release with one movement, and has reflective inserts so drivers can see your dog better after dark.
Harness or collar
A collar presses on the throat and neck when the dog pulls, while a harness spreads the load across the chest and shoulders. That's why harnesses are often chosen for dogs that pull, small and short-nosed breeds with sensitive windpipes, puppies and active walks. A collar is still handy for an ID tag and short outings. A detailed comparison is in how to choose a harness or collar for your dog.

How to choose the size
Measure your dog's chest just behind the front legs at the widest point, and the neck at its base. The name of harness No. 1 gives a chest of 35–45 cm — usually small breeds and medium-breed puppies. If your dog is bigger, look for larger numbers in the same series. A well-fitted harness doesn't slide to one side or rub under the front legs, and two fingers slip easily under the straps. If your dog is between sizes, choose the larger and tighten the straps.
Putting it on and getting used to it
Undo the buckles, put the harness on so the lead ring sits on the back, fasten the buckles and tighten the straps. For the first few days, let your dog wear it at home with praise and treats so it gets used to it quickly. A step-by-step guide is in how to put a harness on a dog. For evening walks you can add a light-up tag or collar to the reflective inserts — tips in walking your dog in the dark.
Caring for the harness
A nylon harness is easy to hand-wash in warm soapy water, especially after muddy walks. Dry it laid out flat, away from radiators, so the nylon doesn't warp. Check the buckles and stitching from time to time: if the plastic cracks or seams come undone, replace the harness so it doesn't come apart on a walk.
Who it suits
Small-breed dogs and medium-breed adolescents with a 35–45 cm chest that walk around town, including in the evening. More models are in the dog harnesses section.
Verdict
Dog Extreme Police No. 1 is a sturdy nylon harness with soft lining, quick buckles and reflective inserts. It's comfortable for daily walks and looks smart. The key is measuring correctly: the product page confuses chest and neck sizes and mentions large dogs.
