Battle Pet Daily Tamer puts a familiar paw on the world map to mark where daily pet tamers are that you have not completed for the day.

From the tracking menu on the world map you can choose to selectively disable/enable:

• Pet Reward Dailies (green paw): These are dailies that reward a pet supply satchel, pet charm or token to buy pet supplies.
• Normal Dailies (blue paw): These are dailies that reward xp but no extra rewards.
• Legendary (orange paw): These are the legendary pets to battle in Tanaan Jungle or in Pandaria if you have picked up the Book of Fables quests.
• Completed Dailies (grey paw): These are the above dailies after they've been completed. It is off by default.
• On Flight Maps Too (flying boot): This setting will show paws on the flight map, so you can choose where to fly closest to a daily. It is off by default.
• Stable Masters (horseshoe): This setting will display a horseshoe on the zone map where stable masters are located. It is off by default.

Special note for Legion world quests:

• Paws do not yet show on the new Broken Isle flight map. This will require some further research. But it's not very pressing since you can zoom in and pan on this map.
• The locations of stable masters in the Broken Isles have not been gathered yet.
