If you walk or run with your dog, one simple answer to "where does my phone go?" is your upper arm. With the leash in one hand, a phone in the other leaves you without a free hand; an armband keeps the phone with you while both hands stay available for the leash and your dog. When you want to use the phone, stop somewhere safe first, with your dog settled beside you.
This post is only about the phone. How far, how fast and how often your dog should run is a separate question for you and your vet.

Why is holding a phone and a leash together so awkward?
Count the jobs your hands already have on a dog walk. One holds the leash. There may be a waste bag to carry, a few treats, a water bottle for your dog and a door key. Add a phone and something has to give: it gets squeezed against the leash handle, swapped from hand to hand, or pushed into a pocket where you can't see it.
A hand wrapped around a phone isn't free to shorten the leash, open a bag or give a good scratch behind the ears. That isn't a statistic, just an everyday juggling act you may already know well. If you're curious about phone-in-hand running more generally, we covered it in is it safe to run holding your phone in your hand?
Where can your phone go so your hands stay free?
There's more than one good answer, and the right one depends on your clothes, your phone and how you like to move:
- A secure pocket can be enough if you don't need to see the screen and the phone sits comfortably while you move.
- A running belt keeps the phone at your waist. If you use a waist-worn leash, check that the belt and the leash attachment don't crowd each other.
- An armband keeps the phone on your upper arm, away from both your hands and your waist.
Our complete guide to carrying your phone while running compares these in more detail. Here, we'll stay with the armband, because it answers the dog-walk question directly: the phone comes along and your hands don't hold it.
How does an armband help on a dog walk?
The LULURUN running armband keeps your phone on your upper arm, so neither hand has to hold it. Its open silicone holder grips the phone at its corners, and no pouch or plastic window sits over the screen.

A snug fit helps minimize bounce; some movement is normal. Before you head out, try a few easy steps, with or without your dog, and adjust the strap so it feels snug without pinching.
The mount rotates a full 360°, so you can adjust how your phone sits on your arm. You might prefer wearing the band on the arm that isn't holding the leash so the leash hand can move freely; try both sides and keep whichever feels natural.
Bags and treats still need a home. A pocket or a bag dispenser on the leash handle can take care of those, so the armband can simply do its one job: carrying your phone.
When should you check or detach your phone?
Pause first. Before reading a message, changing a track or snapping a photo of your happy walking buddy, stop somewhere safe and out of the way, with your dog settled beside you and the leash still in your hand.
The detachable mount uses a 90° twist lock, so your phone can come off while the band stays on your arm. Detach only while you're stopped, and check the mount is securely locked again before you set off.
None of this makes a walk risk-free. It simply keeps your hands on the leash while you're moving and saves the phone for the moments you've chosen to stop. For a closer look at how the mount works, read our twist-lock guide.
What should you check before your first walk with it?
- Your arm: LULURUN states an upper-arm fit of 10–16 inches (25–41 cm). Measure where you plan to wear the band, above the elbow.
- Your phone and case: The stated phone range is 5.0–6.9 inches with slim or clear cases. Thick, rugged and MagSafe wallet cases are not compatible.
- The holder: Seat your phone, check that each corner is held securely, and check the mount is locked.
- The weather: The armband is sweat resistant, not waterproof, and its open holder does not shield your phone from water. On a wet day, plan another way to keep your phone dry.
Then clip on the leash, pick your favorite loop and enjoy the walk together.
