The first part of the walk is easy. Then a truck passes, your dog turns, and the lead goes tight in the direction of home. They may be frightened, tired, hot, sore, or simply ready to finish. You cannot tell from pulling alone.
Check for limping, heavy panting, sore paws, heat, or a sudden change in pace. Stop in a safe place and offer water if appropriate. If your dog seems unwell, cannot walk normally, or this is a new pattern, seek veterinary advice. Don't insist on finishing the route just to prove they can.
Read the turning point
Note where they begin to pull. Is it near traffic, a particular dog, a noisy building site, or after a long distance? Try shorter walks that turn back before the hard point. Give time to sniff and choose a quiet route. If your dog relaxes once away from a specific place, that is a clue about what needs changing.
Practice loose-lead walking in a low-pressure area, rewarding your dog for moving with you while the lead is slack. Don't turn the urgent trip home into a stop-and-start lesson if your dog is scared or uncomfortable. Training a calmer response to a trigger can come later, at a distance where they can still eat and move freely.
A dog who pulls home is not making a case against every walk. They may be showing you exactly where today's walk stopped working.
