If you've ever switched between a dog walking bum bag in summer and a crossbody bag in winter, you already know the frustration. The bag that's perfect for a quick training session at the park feels awkward over a thick jacket. The bag that carries everything beautifully for a long beach walk swings into your face the moment you crouch to pick up after your dog.
Here's the thing: the bum bag vs crossbody debate isn't really a debate at all. It's a false choice. You have different walks, different seasons, and different needs depending on the day. The real question isn't which style is better, it's whether your bag adapts to you, or you adapt to it.
What Bum Bags Do Brilliantly
Dog walking bum bags earn their loyal following for one core reason: they don't move. When you bend to pick up poop, crouch to greet a dog, or change direction quickly mid-walk, the bag stays locked at your hips. This stability is the single biggest functional advantage, and it's why professional dog trainers and walkers with reactive or in-training dogs consistently reach for them first.
Weight sits at your body's centre of gravity — your hips and lower back — so the bag doesn't shift or swing during movement. For training sessions where reward timing matters, this is everything. You can reach into a front-mounted bum bag mid-stride without breaking rhythm, delivering treats at exactly the right moment.
In summer, when shorts and a tee leave you with zero pocket space, a bum bag replaces your pockets entirely. Most dog owners describe forgetting the bag is even there once they're used to it.
Where Bum Bags Fall Short
The trade-offs become obvious as soon as the weather turns. Over a thick winter jacket, bum bags are fiddly to adjust, awkward to access, and uncomfortable to wear for any length of time. This is the number one reason dog owners switch styles seasonally.
Capacity is the other limitation. Most dog walking bum bags carry enough for treats, poop bags, phone, and keys — but not a full water bottle, towel, or spare lead. For walks under 30 minutes, this is fine. For longer adventures, you'll find yourself wishing for more space.
Hot weather brings its own problem: the bag presses directly against your body. In Australian conditions especially, a bag sitting against your stomach during a morning coastal walk can leave you with an uncomfortable sweat patch. Budget bum bags rarely include breathable mesh backing to help with this.
What Crossbody Bags Do Brilliantly
Dog walking crossbody bags are the most popular style for good reason. They carry more, layer beautifully over winter coats, and look stylish enough to wear from dog walk to café without a second thought, a genuine consideration for Australian dog owners who walk to the beach and then sit down for a flat white.
The diagonal strap sits easily over any jacket, with no waistband adjustment needed. This all-season versatility is the primary reason crossbody converts bum bag users every autumn. Greater capacity means you can fit everything a bum bag carries plus a slim water bottle, wipes, a small towel, or a spare lead, making crossbody the clear choice for longer walks.
The larger form factor also means better organisation. Multiple dedicated compartments keep treats separate from your phone, poop bags separate from valuables, and everything accessible without digging.
The One Problem Everyone Mentions
Every crossbody bag review eventually gets to the same complaint: the swinging. When you bend to pick up poop, reach to interact with a dog, or move quickly, the bag swings forward. This is cited again and again across forums, professional reviews, and dog trainer blogs as the defining drawback.
Professional dog walkers who work off-lead trails often dismiss crossbody bags entirely for this reason. One trainer put it bluntly: the bag ends up in the mud when you crouch down, or worse, swings into your dog's face when you bend over to greet them.
Treat access is also slower than with a bum bag. The bag sits at hip level rather than front and centre, requiring a longer reach. For casual neighbourhood walks this is negligible; for active training, the difference in timing matters.
The Pattern That Emerges
The most consistent finding across all the dog walking communities is that experienced owners don't choose one style — they switch. The pattern is nearly universal:
Bum bag in summer: fewer clothing layers, shorts provide no pockets, shorter walks in the heat, quick park sessions where training is the priority.
Crossbody in winter and for longer adventures: easier to wear over coats, more carrying capacity for wet weather gear, longer walks that demand more hydration and supplies.
This seasonal switching behaviour reveals what dog owners actually want: a bag that does both. Not two bags for different occasions, but one bag that adapts.
The Features That Actually Matter
Across hundreds of reviews and forum discussions, certain features surface consistently as non-negotiable, regardless of which style you prefer.
A built-in poop bag dispenser is the most universally valued feature. A pull-through slot that lets you grab a bag without opening anything else saves time on every single walk.
Quick-access treat storage that's easy to open, close, and clean makes training smoother. Fabric pouches that absorb treat residue and odours are the number one complaint from long-term bag owners.
A secure phone pocket large enough for modern phones, with an internal key clip so nothing falls out when you're reaching for bags or treats.
Water-resistant material is essential in Australia for rain, beach spray, and wet grass. A bag that can't handle getting splashed isn't fit for purpose.
Multiple organised compartments — at minimum three — to separate treat crumbs from valuables and keep everything accessible.
In Australian conditions specifically, a water bottle holder is near-essential. Summer walks without hydration aren't just uncomfortable; they're unsafe for you and your dog.
Why Choose When You Don't Have To
The research points to an obvious conclusion: the best dog walking bag isn't a bum bag or a crossbody. It's a bag that converts between both.
That's exactly how we designed the Amalfie Dog Walking Bag. A single adjustable strap lets you wear it at your waist like a bum bag for summer walks and training sessions, or lengthen it to a crossbody for winter layering and longer adventures. One bag, all year, every walk.
The crossbody-length strap also addresses the swinging problem. Worn at the right length and angle, the bag sits closer to your body and moves with you rather than against you.
Built for How Australians Actually Walk Their Dogs
Our fold-out mesh water bottle holder solves one of the top complaints about bum bags: limited capacity. It folds away when you don't need it, keeping the bag compact for quick walks, and pulls out when you do. This is the kind of design detail that separates a purpose-built dog walking bag from a generic fanny pack with a carabiner clipped on.
The quick-access front pocket keeps treats right where you need them. For owners who want a fully dedicated treat compartment, our Silicone Treat Pouch clips on and wipes clean — no more fabric pouches absorbing smells and crumbs.
Everything else dog owners tell us they need is already built in: poop bag dispenser, organised compartments, phone pocket, key storage, and splash-proof construction that handles beach spray and morning dew without a second thought.
The design is understated enough to go from the dog park to a café without looking like you've come from a training session. Because in Australia, that's exactly how most dog walks end.
Frequently Asked Questions
Is a bum bag or crossbody better for dog training?
Bum bags have the edge for active training sessions because they stay stable when you move and keep treats at the front of your body for faster access. However, a convertible bag worn at the waist gives you the same benefits with the flexibility to switch styles when you need to.
Why does my crossbody dog walking bag swing so much?
Most crossbody bags swing because the strap is too loose, allowing the bag to hang too low. Adjust so the bag sits between your ribcage and hip, close to your body. Wider straps also help distribute weight more evenly and reduce movement.
What should I carry in my dog walking bag?
The essentials are poop bags, treats, your phone, and keys. For longer walks, add a water bottle and collapsible bowl. In Australia's variable weather, it's worth keeping a small towel or wipes for muddy paws or unexpected beach detours.
Are dog walking bum bags comfortable in hot weather?
They can be, but cheap bum bags that press directly against your body without breathable backing will leave you sweaty. Look for bags with mesh panels or the option to wear them slightly away from your body as a crossbody in the hottest conditions.
Can I use a regular fanny pack for dog walking?
You can, but you'll miss features designed specifically for dog owners: poop bag dispensers, treat-accessible pockets, and compartments sized for the gear you actually carry. A purpose-built dog walking bag makes daily walks noticeably smoother.
