A dog walking bum bag sits snugly around your waist, keeps both hands free for the lead, and puts treats, poo bags and your phone exactly where you can grab them without breaking stride. It's the minimalist's choice — less bulk than a cross-body, quicker than a rucksack, and impossible to lose behind your back when you bend down to scoop.
This is our UK 2026 guide to dog walking bum bags: when they genuinely beat a cross-body, how to pick one that survives British weather, and which bag we recommend for everyday walks, runs and longer countryside routes. If you're weighing up every bag style at once, start with the main dog walking bag guide, then come back here for the bum-bag deep dive.

Why a Bum Bag Works for Dog Walks
A bum bag — sometimes called a waist bag, belt bag or fanny pack — sits horizontally around your hips on a wide belt. For dog walking, it has a handful of small but meaningful advantages over other styles.
In our experience on muddy British commons and pavement walks alike, three things make it earn its place:
- It never shifts. The belt is under your coat and grips your waist — no slipping, no swinging, no clunking against your dog when they walk close.
- It centres the load. Weight sits on your hips (your strongest load-bearing joint), not pulling down one shoulder.
- It clears your torso. Nothing cross your chest, so your coat zips, scarves and running vests all still work normally.
It's the go-to style for runners, long-distance walkers, and anyone who finds a cross-body bag too bulky in summer. If that's you, there's a strong case for making a bum bag your primary walking bag — and the dog walking bags collection has styles designed specifically for walking (not fashion bum bags retrofitted with a poo bag loop).
Bum Bag vs Cross-Body vs Shoulder Bag
The honest answer: neither bum bag nor cross-body is universally "better" — they're right for different walks and different owners. Here's how they actually compare once you've used both.
| Style | Best For | Weak Point | Typical Capacity |
|---|---|---|---|
| Bum bag | Runners, summer walks, minimalists, commuters fitting a walk in before work | Smaller capacity; the belt can dig in over a winter coat | 0.5–2L |
| Cross-body | Everyday park and pavement walks, reactive-dog handlers who treat often | Sits across the chest — some people dislike the warmth in summer | 1.5–3L |
| Shoulder bag | Short walks only, fashion-first, small dogs who don't pull | Slips off when you bend down; rarely genuinely hands-free | 1–3L |
| Rucksack | All-day hikes, water bowls, carrying a towel | Overkill for a 30-minute walk; slow to access | 5L+ |
If you're still torn between bum bag and cross-body, our dog walking bag cross body guide goes deeper on that style specifically. For a broader overview of every walking bag type, the dog walking bag pillar guide compares all four styles head-to-head.
In our experience: owners who walk once or twice a day for 20–30 minutes on pavement tend to prefer a bum bag. Owners who walk a reactive dog, train with treats constantly, or carry a water bottle on longer walks tend to prefer a cross-body. Neither group regrets the choice, which tells you it really is a lifestyle fit.
What to Look For in a Dog Walking Bum Bag
A fashion bum bag from a high-street shop will let you down on a rainy Tuesday. Here's what actually matters in a bag designed for dog walks.
A Real Poo Bag Dispenser
Not just a D-ring to tie a bag to. A dedicated dispenser — internal roll holder or side-fed slot — means one-handed access while the other hand holds a straining lead. See our poo bag holders collection for the standalone versions if your current bag lacks one.
An Adjustable Belt That Fits Over a Winter Coat
Belt range matters more than capacity. Look for at least 70–130cm so the bag fits bare-waisted in summer and over a padded coat in January. A squeaky-short belt is the single most common complaint about cheap bum bags.
A Front Treat Pocket
Front-facing, one-handed opening (magnetic flap or quick-pull zip). Lined or wipe-clean so soft training treats don't leave chicken grease in your main compartment.
Water-Resistant Fabric
Coated canvas or ripstop nylon with sealed seams. British weather doesn't need submersion-proof bags, just something that shrugs off 20 minutes of drizzle while your phone stays dry.
Internal Organisation
- A zipped valuables pocket for keys and bank card
- A phone sleeve that stops your screen bashing against keys
- External D-ring for a used poo bag or a damp tennis ball
- Reflective trim if you walk at dawn or dusk
Watch out for: fashion bum bags with flimsy polyester belts. They stretch out within a month of daily use, end up rotating round your waist, and bury the pocket against your lower back exactly when you need treats. Go for walking-specific construction.
How to Wear a Dog Walking Bum Bag
A good bag worn badly is still uncomfortable. Two minutes adjusting it the first time pays back every walk after.
Front, Side or Back?
Three positions, three reasons:
- Front — most practical for dog walking. Everything is instantly in reach, you can see the pockets, and it doesn't bounce when you bend down to clip a lead.
- Hip (side) — comfortable for long walks and running. Swing it to the front when you need treats.
- Back — fine for casual wear, but genuinely poor for dog walks. You can't see the pockets, it bounces, and it digs in when you sit on a bench.
Belt Tightness
Snug enough that it doesn't shift when you walk — loose enough that you can fit two flat fingers between the belt and your hip. Tighter and it'll dig in; looser and it'll rotate within a mile.
Winter Coat Trick
Wear the belt over your coat, not under it. Counter-intuitive but it keeps the pockets accessible — wearing it under the coat means unzipping every time you need a treat.
Pro tip: if you're walking in heavy rain, wear a long waterproof jacket over the bum bag and lift the hem when you need to access it. Your bag stays bone dry and you're not struggling with a zip in the rain.

What to Pack in a Dog Walking Bum Bag
Bum bags are small — under-pack them, not over-pack them. Anything heavier than about 500g starts to drag on the belt and rotate round your waist.
The Essentials (always in the bag)
- A roll of poo bags (in the dispenser, not loose)
- A small stash of high-value treats (not a whole pouch's worth — refill at home)
- Your phone
- Keys on the internal clip
- A contactless card or slim card holder
The Situational Extras
- A collapsible water bowl for hot-day walks
- Small hand sanitiser
- A tennis ball or small tug toy (external D-ring, not inside)
- A spare poo bag roll for longer walks
What Not to Pack
A water bottle (belt sag), a handbag's worth of personal kit (wrong bag), a second lead (clip it to your belt directly or use a cross-body). If you find yourself adding things you don't use, take them out next walk.
Pro tip: if your dog is in heavy training, keep a clip-on treat pouch alongside the bum bag for rapid-access rewards. The bum bag holds phone, poo bags and keys; the pouch holds the training treats.
Frequently Asked Questions
Is a bum bag better than a cross-body bag for dog walking?
Neither is universally better — they suit different walks. A bum bag is smaller, runs cooler in summer, and sits flat against your body, making it ideal for runners and minimalists. A cross-body carries more and keeps pockets closer to your hands for frequent treat access, making it better for reactive-dog owners and long walks. Most UK dog owners eventually own one of each.
What size dog walking bum bag do I need?
For short daily walks with a single dog, 0.7–1.5L is ideal — enough for phone, keys, cards, treats and a poo bag roll. Runners and canicross owners usually prefer the smaller 0.5–0.8L slimline style for minimal bounce. If you need more than 2L, you've probably outgrown a bum bag and should look at a cross-body or small rucksack instead.
Can I wear a dog walking bum bag over a winter coat?
Yes, and you should. Wearing the bum bag over your coat keeps pockets accessible so you're not unzipping your jacket every time you need a treat. Look for a bag with a belt that extends to at least 130cm so it fits comfortably over a padded winter coat — short belts are the single most common failure point on cheap bum bags.
Are dog walking bum bags waterproof?
Most quality dog walking bum bags are water-resistant rather than fully waterproof. They'll shrug off light rain and keep your phone and treats dry during a typical British walk, but they aren't designed to be submerged. Look for coated canvas or ripstop nylon, sealed seams, and YKK zips. If you walk in heavy rain, wear a long waterproof jacket over the bag.
Where should I wear my bum bag — front, side or back?
Front for dog walking, side for running, avoid the back. Wearing the bag at the front means you can see the pockets, access treats one-handed, and the bag doesn't bounce when you bend down to scoop. Side-hip works well for running or long-distance walking. Back-worn bum bags are fine for casual wear but genuinely impractical for active dog walks.
Can I use a bum bag for running with my dog?
Yes — a slimline running-style bum bag is one of the best options for canicross and jogging with a dog. Look for elasticated belts, ripstop fabric, a snug close-fit profile, and a front-facing phone pocket. Avoid bulky everyday walking bum bags for running because they bounce; a purpose-built running bum bag sits flat against your body and barely moves.
Final Thoughts: Is a Bum Bag Right for You?
If you walk once or twice a day on pavement or local parks, run with your dog, or just like minimalist kit, a dog walking bum bag is probably a better fit than a cross-body. It's smaller, cooler in summer, and stays put on your hips without ever sliding off a shoulder.
If you carry more (water bottle, towel, ball launcher) or train a reactive dog with constant treats, size up to a cross-body — the main dog walking bag guide covers the full range of styles and will help you land on the right one.
