Count what you are holding on a normal walk. Lead in one hand. Phone in the other, because you are on the last ten minutes of a podcast. Treats in a coat pocket, which means treat crumbs in a coat pocket for the rest of the winter. Poo bags in a different pocket, or more likely in the pocket of the other coat, the one hanging in the hall. Keys somewhere. And then the dog spots a squirrel and you need a hand you do not have.
Most people solve this by buying a bigger coat. It works until April. A dog walking bag solves it properly, and once you have walked with one for a fortnight you will not go back. This guide covers how to choose one, what to look for in the spec, and the more useful question that nobody writes about: what genuinely deserves to go inside it.
The short answer
For most UK owners, a crossbody or bum bag in water resistant fabric, roughly 24cm wide, with two or three separate compartments and a strap that adjusts properly, is the right shape. Look for a strap that extends past about 130cm so it can be worn either way, and a lining in a bright colour so you can find your keys in the dark. You do not need a rucksack unless you are walking all day.
Why a dog walking bag beats coat pockets
Three reasons, and only the first is obvious.
Both hands stay free. The moment that matters is not the calm part of the walk, it is the recall, the sudden pull, the other dog coming round the corner. Fumbling a phone into a pocket while a lead tightens is how leads get dropped.
The kit stops living in the wrong coat. This is the real win. Once poo bags, treats and a spare lead clip live in a bag that goes on the hook by the door, they are on every walk, in every season, regardless of what you are wearing. Nothing gets forgotten because nothing gets moved.
Treats stay separate from everything else. Liver in a pocket with a phone is a decision you make once.
The four bag shapes, and who each suits
Crossbody or bum bag. The default, and the right answer for the vast majority of daily walks. Small enough to forget you are wearing it, big enough for the real list. Worn round the waist when you want everything to hand, or over the shoulder when you would rather it sat out of the way.
Treat pouch. A dedicated training pouch with a wide opening. Excellent while you are actively training, less good as an everyday bag because it holds treats and almost nothing else.
Small rucksack. Right for a full day out, a beach trip or a walk where you are carrying water and a coat. Overkill for the twenty minutes before work, and it takes the weight off your hips and puts it on your shoulders, which you feel on a long walk.
Lead-mounted pouch. Clips to the lead itself. Genuinely neat for poo bags and one or two treats. Not a replacement for a bag, because the weight ends up on the lead and therefore, eventually, on the dog.
What to look for in the spec
Walking bags are one of those categories where the spec sheet actually predicts whether you will still be using it in a year.
Water resistance. Non-negotiable in Britain. You are not looking for submersible, you are looking for a fabric that shrugs off drizzle, wet grass and a shake from a dog standing slightly too close. A nylon outer does this well. Nothing that soaks up water and stays damp in a hallway.
Compartments, plural. One big pocket is a bag of loose objects. Two or three compartments is a system. The dividing line is whether treats can be reached without moving your keys.
Strap length that genuinely adjusts. The single most common failure. A strap that only just reaches when you are in a t-shirt will not go round a winter coat. Look for a strap that extends to at least 130cm, which is what makes a bag work as both a bum bag and a shoulder bag.
A bright lining. This sounds like a detail and is not. From late October you will be doing at least one walk a day in the dark, and finding a black key fob inside a black bag by torchlight is a small daily irritation with an easy fix.
Hardware that will not seize. Zips are what fail. Metal hardware, and a zip pull big enough to work with cold hands or gloves on.
Size, honestly assessed. Around 24cm wide by 21cm tall by 8.5cm deep takes a phone, a roll of poo bags, a treat pouch, keys and a folded spare lead. That is enough. Bigger bags get filled with things you then carry for a year without using.
The two we stock
Worth saying plainly, since it catches people out: these are bags for you, not for the dog to wear.
Dobbybags The PEBBLE Crossbody Dog Walking Bag in Grey is £34.99. Water resistant 290T nylon outer in soft grey, 210D polyester lining in bright blue, silver zinc hardware. It measures 24cm wide, 21cm tall and 8.5cm deep, with multiple compartments and an included treat pouch, and the strap runs fully out to 136cm so it works round the waist or across the body. The grey is the understated one, and the flash of blue inside is the bit that makes finding things easy.
Dobbybags The OG Crossbody Dog Walking Bag in Black is also £34.99 and is the original in the range. Same dimensions, same 136cm strap, same water resistant nylon, but black outside with a neon yellow lining, which is the more emphatic answer to the finding-things-in-the-dark problem.
Both are made by Dobbybags, a British brand based in Bracknell built around the idea that walks are better with your hands free. Choose on colour and lining, because the rest of the spec is identical.
What actually earns a pocket
Here is the part that matters more than the bag. A walking bag is only useful if what is in it is genuinely used. This is the list we would defend.
Poo bags, more than you think. Keep a full roll in the bag and never rely on the two in your coat. The one walk you run out on will be the one where it matters.
Treats worth having. Not the everyday biscuit, the good stuff, kept for recall. A treat that is only slightly better than the grass is not a recall reward.
Your phone. Not for the podcast. For the photograph of the injury, the call to the vet, the map when you have taken a wrong turn in the dark.
A spare lead or a slip lead. Weighs almost nothing. Covers a broken clip, a dog who needs help, or a stranger's loose dog that you end up walking to a gate.
A small torch or a clip light. From late October onward this earns its place daily. A head torch is better still if you are walking off-road.
A folded cloth or small towel. For paws before the car, for a cut, for the fox poo emergency. It will get used far more than you expect. If that last one is a regular event on your route, our guide to getting fox poo off a dog is the companion piece to this one.
Water in summer, and on long walks year round. A collapsible bowl folds flat.
What does not earn a pocket: a second toy, a full first aid kit for a twenty minute road walk, and anything you have carried for a month without touching.
Bag or hands-free lead?
People often assume these compete. They do not, they solve different halves of the same problem. A bag frees your hands from carrying kit. A hands-free lead frees your hands from the dog.
Together they are the full solution, and the combination is what makes a walk with a pushchair, a coffee or a second dog actually workable. Our Timeless Hands-Free Dog Lead in handmade leather is £49.99 and is the piece that goes round your waist or across the body while the bag takes the kit. If you prefer a conventional lead in hand, the Timeless Dog City Lead is £44.99 and is the shorter, more controlled option for pavements and towns.
If you are still working out lead length and width for your dog, we go through it properly in How to Choose a Dog Lead.
A note on carriers, which are a different thing
A dog walking bag is worn by you and holds kit. A dog carrier is worn by you and holds the dog. They get confused constantly online because the search terms overlap. If what you actually want is to carry a small dog, that is a separate purchase with entirely different criteria around ventilation, structure and weight limits, and we cover it in Best Dog Carriers and Travel Bags.
Looking after it
Wipe the nylon outer with a damp cloth and let it air dry. We would keep it to spot cleaning rather than putting it through the machine, because a wash cycle strips the water resistant finish faster than anything a walk will do to it. Empty it out once a month. Every walking bag in Britain accumulates a fossil layer of crumbs, one glove and a receipt.
Frequently asked questions
What size dog walking bag do I need?
Around 24cm by 21cm by 8.5cm is the sweet spot for daily walks. That takes a phone, a full roll of poo bags, treats, keys and a folded spare lead. Anything larger tends to get filled with things you never use.
Is a crossbody bag or a bum bag better for dog walking?
Whichever you prefer on the day, which is why a strap that extends fully to around 136cm matters. Round the waist keeps everything closest to hand for training. Across the body is more comfortable on a long walk and easier over a winter coat.
Are dog walking bags waterproof?
Most, including ours, are water resistant rather than waterproof. That covers rain, wet grass and a shake from a soaking dog. It does not cover being dropped in a river, so keep anything critical in a small sealed pouch inside.
Can I use a normal bum bag instead?
You can, and plenty of people do. The differences that show up over a season are the water resistant fabric, the separate treat compartment, and a strap long enough to go over a coat. A festival bum bag will do a summer, then let you down in November.
How do I clean a dog walking bag?
Wipe the outer with a damp cloth and air dry it. Avoid the washing machine, which degrades the water resistant finish. Turn the compartments out and shake the crumbs into the bin once a month.
Do I still need pockets if I have a hands-free lead?
Yes. A hands-free lead deals with the dog, not with the kit. The two together are what actually make a walk feel easy.
What should I carry on an autumn or winter dog walk?
Poo bags, high-value treats, phone, spare lead, a light, and a folded cloth for paws and mud. Add water on longer walks. Everything else is optional.
Where to start
If you are buying one thing this autumn, make it the bag rather than another coat. It is the piece that quietly fixes the routine rather than the weather.
Both Dobbybags are in Walkies alongside the leads, collars and harnesses, and if the rest of the season needs sorting, The Autumn Walk Kit covers what else genuinely earns its place. Free UK delivery on orders over £30.
