We built Whistle with family, friends, and pet sitters in mind, so there is no limit to the number of people that may be a part of the experience.

However, there is a limit to the number of people that may be assigned as owners and pair with Whistle Activity Monitor for presence data. This is limited to six people. Click here for more information on Whistle's presence feature.

You can also add friends and follow other dogs through our Whistle Community Board.

As an owner, there is no limit to how many pets you can have, although each pet will need its own Whistle.
