Any tips for walking multiple dogs?

It's always awkward at first when you add dogs to the mix that aren't used to walking together. I find that the best solution is time. After a couple days of really awkward walks, the dogs get into the rhythm a bit more. For my own dogs I've taught them some basic commands to help untangle which work with mixed results. Mine know "back up," "wait," and "go around." Sometimes that will prevent or undo a tangle, but occasionally it ends in a bigger knot.

I also will use clips to attach the leashes of my good walkers (no pulling, no darting around) to my belt or belt loops, which allows me to go hands-free for those dogs and focus my hands on keeping the more energetic dogs' leashes straight.

Leash splitters (aka couplers or dual lead adapters) can be useful if you're dealing with dogs of similar size and energy. If the dogs are mismatched, you run the risk of one dragging the other around, but if the dogs are both mellow (or both hyper) and roughly the same size, they can work well to minimize the amount of tangle happening. The other time it might be useful is if you have a larger mellower dog paired with a smaller energetic dog, provided the size difference isn't too great and the larger dog doesn't mind the arrangement. Your mileage may vary.

This is an amazing question that I can't wait to read the other answers too! I usually do hikes instead of structured walks with that many dogs. When I do structured walks, I do a few things. First, if I'm doing structured walks around the neighborhood on roads, no dog gets more than a foot and a half of slack, so they're all walking by my side. If they start pulling, I'll take up a bit of the slack and pull up to get them to slow down (no tugging, just a slow, gradual pull). The other thing I can think of is using carabiners to either hook leashes together while you hold on in the middle or you can use a carabiner to loop the handle of a leash around a tree and hook it to itself to give you an extra hand to untangle while the tree holds the pup. Rover also has a blog post on this from last year here https://www.rover.com/blog/walk-multi...

I walk our 4 small untrained dogs together using our own UTurn handle, three dogs on the handle and the best non-tangler on a separate 4th leash. You untangle any leash in seconds by turning/flipping the handle while walking or passing the 4th leash around the others. If you replace the 4th leash with a 2-way or 3-way coupler with a long main lead plus very short end leads you can walk 5 or 6. Walking so many (untrained or half-trained) dogs is only recommended if you can control them at all times (must be small and/or docile). Paul
