If you walk a dog every day you get through poo bags quickly, and running out halfway round the park is the one thing you don't want. Buying in bulk means there is always a roll in your coat pocket, the car and the drawer by the door.

This pack holds 55 rolls of 20 bags, 1100 bags in total, plus a bone-shaped dispenser with a clip that hooks onto your dog's lead. Each bag measures 30 x 22cm and has a textured surface that makes it easier to open on a cold morning. Pull a bag from the dispenser, pick up, tie the open end and bin it; when the roll runs out, drop the next one in. Spare bags are handy around the house too, for nappies, wet clothes or the car bin.

• 1100 bags on 55 rolls
• 20 bags per roll
• Bag size: 30 x 22cm
• Bone-shaped dispenser with lead clip

• Pack weight about 1.1kg

Worth knowing: the maker describes these as degradable plastic bags but names no composting standard, so treat them as general waste and put them in a dog-waste or household bin, not on a compost heap. Keep the spare rolls somewhere cool and dry, out of direct sunlight.
