Alert when a llama stops following caravan

Its almost impossible to tell when a llama stops following the caravan, especially if its the last llama (#10) in line behind the leader with the lead. Theres a bunch of llamas in front of it so you cant just turn around and see it, and it gets confusing having to recount overlapping animals, many of which look the same. Going in circles is inefficient and only exposes the rest of the caravan to new obstacles when you go back to check if you lost a llama.

All of this could be avoided if there was a sound effect like a specific yelp that llamas make to notify you that they can't continue following the caravan because of some obstacle. This sound has to be loud enough to hear from the back to front of the caravan where the player is holding the lead.

Edit \/

Alternate solution: if one llama gets stuck, all of the llamas stop in the caravan, including the first one that is tied to a lead, alerting the player that something went wrong. To make sure the player realizes this, a sound for leads breaking/dropping would be an effective notification if the player kept walking while the llamas were stopped. \/

There is a post about a sound effect for currently held leads breaking, which I think is a needed addition as well (https://feedback.minecraft.net/hc/en-us/community/posts/360043049791-String-Lead-Sounds), but please realize that this post is a different request than just leads and deals with the function of llama caravans exclusively.
