Good to know
Several pets?
Activate each pendant separately, using the same phone number or email, so all your pets are in one account.
Camera won’t scan?
Find better light, wipe the pendant, and hold the phone 10–20 cm away. On some Android phones, use Google Lens.
The code didn’t arrive?
Check the number and wait a minute before trying again, or choose email instead and use the sign-in link. If the link isn’t in your inbox, check spam or promotions.
It says “This Tail-O ID isn’t available”?
