You take one side of a tree. Your dog takes the other. One more step and the leash catches, usually just as your dog finds the most interesting smell on the block. You do not need to turn every walk into strict heelwork to avoid this. A little route planning and a practiced turn can make the whole exchange easier.
First, stop moving. Pulling harder from the opposite side does not create a clear path back. Keep hold of the leash, look at where it runs, and make the simplest safe route available.
Stop and undo the route, not the dog
If you can safely step around to your dog's side of the tree, that may be the easiest reset. Keep your dog close enough that neither of you needs to step into the road or across another person's path. Otherwise, encourage your dog to retrace the route they just took, using a familiar turn cue or a treat to guide them.
Let the leash slacken as your dog comes back around. Do not jerk it against the trunk or drag your dog sideways. Dogs Trust's loose-lead guidance favors calm pauses and rewards, not leash jerks. If the line is caught low around a leg, stop the walk and calmly free it while keeping your dog secured. Do not try to solve a tangle by letting go in an open area.
There is no need to make your dog figure it out under pressure. Help with the easy route, reward when they reach you, and carry on. If your dog is excited by something beyond the tree, move away from that distraction once the line is clear rather than turning the reset into a struggle.
Teach an easy go-around away from traffic
Pick a quiet, open space and one wide, stable obstacle. Start with you and your dog on the same side. Guide your dog a small part of the way around with a treat held near their nose, then back toward you. Keep the leash loose and the movement easy. Reward when they follow the route.
The American Kennel Club's walking-games guide describes using a food lure to teach going around tree trunks, then adding a verbal cue and gradually reducing the lure. Use that as a small training game, not a test in a live tangle. Begin with a short arc before trying a full turn, and avoid narrow gaps or anything the leash could snag on.
Once the movement is familiar, add a short cue such as "around" as your dog follows it. Over later repetitions, use a smaller hand gesture, then reward after the turn. Practice both directions separately. Blue Cross's training guidance explains why timing matters: the reward should follow the action you want repeated.
Prevent the next knot without ending the sniff
As you approach a post or tree, choose the same side before the leash splits around it. Give your dog enough room to sniff without letting the line cross a walkway. You can move with them around a tree where there is safe space, or invite them back before you continue.
A fixed-length leash makes the available space more predictable on a busy sidewalk. AKC's retractable-leash guidance specifically warns about tangles around tree trunks and fire hydrants. This is a reason to choose equipment for the setting, not a claim that one leash solves training by itself. Check local leash-length rules too.
Keep the practice short. If your dog stops following the cue, go back to an easier place or use management for the rest of the walk. The RSPCA recommends short, regular loose-lead sessions and rewards for staying nearby. A few easy turns are more useful than repeating the same difficult loop until both of you are frustrated.
Sniffing is still part of the walk. Build a simple pattern: explore where there is room, come around when asked, then explore again.

These steps apply reward-based training guidance to an everyday handling task. Keep control of your dog and choose space over a difficult repetition. Local leash and waste rules vary.
