GUI Followers is a client-side mod which shows a list of all tamed non-sitting following mobs around the player. By default it also shows the health of the follower as a percentage, and how many blocks it is away from the player. Fully configurable! You'll never accidentally leave your wolf buddy behind.

Pets you don't want in the list can be hidden with a command, and will show up again once they sit down. Specific entities can also be ignored entirely via the config. The durability of a wolf's armour is shown as well, so you'll know when it needs to be repaired. The list can be moved, scaled and optionally coloured based on the follower's health.

Environment: Client

All available config options:

If enabled, shows the durability of a follower's armour (like wolf armour) in the GUI list.

wolfArmourFormat  default " [Armour <armour>%]"
The format of the armour string in the GUI. <armour> will be replaced by the percentage of durability left.

showFollowerDistance  default true
If enabled, shows the follower's distance in blocks to the player in the GUI list.

followerDistanceFormat  default " (<distance> blocks)"
The format of the distance string in the GUI. <distance> will be replaced by distance in blocks.

distanceToCheckForFollowersAround  default 50, min -1, max 300
The distance in blocks around the player where the mod checks for tamed, non-sitting followers to add to the list. A value of -1 disables this feature.

timeBetweenChecksInSeconds  default 2, min 0, max 3600
The time in seconds in between checking for tamed, non-sitting followers around the player.

entityTypesToIgnore  default "workers:*"
A comma-separated list of entity ids that are never shown in the follower list. Use '<modid>:*' to ignore every entity of a mod. By default contains the workers from the Villager Workers mod, which always follow.

followerListPosition  default "Left"
Where the follower list is shown at the top of the screen.

followerListHeightOffset  default 20, min 0, max 3000
The vertical offset (y coord) for the follower list. This determines how far down the list should be on the screen. Can be changed to prevent GUIs from overlapping.

followerListWidthOffset  default 0, min -3000, max 3000
The horizontal offset (x coord) for the follower list. A positive value moves the list to the right, a negative value to the left.

followerListTextScale  default 1.0, min 0.5, max 3.0
The size of the follower list text. 1.0 is the normal size.

drawTextShadow  default true
If the text displayed should have a shadow drawn below it.

colourFollowerByHealth  default false
If enabled, a follower's line changes colour based on its health, using followerHealthColours.

followerHealthColours  default "75:255,255,85;50:255,170,0;25:255,85,85"
A list of <health percentage>:<R>,<G>,<B> entries separated by a semicolon, with RGB values from 0 to 255. A follower at or below that health percentage is shown in that colour. Used when colourFollowerByHealth is enabled.

RGB  default "255,255,255"
The colour of the follower list text, as red, green and blue values from 0 to 255.

/guifollowers hide - Hides the pet you're looking at from the follower list, until it sits down again.
/guifollowers hide <name> - Hides all followers in the list with that name.
/guifollowers unhide - Shows all hidden followers in the list again.

The wolf named buddy shown in the GUI:

The wolf buddy is currently at 85% health. I did feel a little bad about testing this.

Sitting entities will not be added to the follower list.

Long distances are supported.

And last but not least, a GIF showing the feature:
