LIKER Lumi 5 is a ball for puppies and small dogs from the Ukrainian company COLLAR with a photoluminescent cord that glows in the dark. The ball is 5 cm across and the cord 30 cm long. The cord glows for up to 60 minutes, so play can continue into the evening. According to the manufacturer, LIKER's material combines the qualities of rubber, plastic, nylon and cotton: it's light, springy, gives under the teeth without hurting teeth or gums, and floats. The colour is orange.
Why a ball on a cord
A cord makes play easier and safer: you can sling the ball a long way, and in tug games your hand stays a safe distance from your dog's teeth. The rubberised cord doesn't cut your palm. It helps get a dog excited, adds intensity to training and suits fetch and tug games. For ideas on keeping a dog busy, see how to keep your dog busy indoors in bad weather.

Charging the cord
The photoluminescent cord charges from light: hold it in the sun or under a bright lamp before an evening walk. The glow lasts up to 60 minutes and gradually fades, so on long walks recharge it under a street light or your phone torch. To make your dog itself more visible, add a light-up tag or collar — more in walking your dog in the dark.
Lumi 5 or Lumi 7
The 5 cm Lumi 5 is designed for puppies and small breeds — Chihuahuas, toy terriers, Yorkies, Jack Russells. Bigger dogs have the 7 cm version: LIKER Lumi 7. A ball should be big enough that your dog can't swallow it, yet easy to grip.
Playing safely
Play together and put the ball away afterwards — interest lasts longer, and your dog won't chew it out of boredom. The manufacturer recommends hiding LIKER after play. Check the ball and cord regularly and replace the toy if pieces are chewed off. Make sure your dog doesn't swallow the ball or any part of it.

For puppies

Care
Wash the ball in warm soapy water after outdoor play — the material cleans easily. Dry at room temperature. Don't leave the toy in the sun for long or near a heater.

Verdict
The LIKER Lumi 5 is a light, soft 5 cm ball with a photoluminescent cord that glows for up to 60 minutes, floats and is kind to your dog's teeth.
