Why is there only personalized ringtones in my cool dog, but no ringtones?

If it is necessary to set the cool dog's music as ringtone, you can download songs in the cool dog app first, and then add the local songs of your mobile phone to the ringtone settings in the mobile phone settings. If it is an iphone, you need to connect the data cable to the computer to complete the operation of adding ringtones to the computer. If it is necessary to set the ringtone as a ringtone, you can make the music downloaded from Cool Dog into a ringtone and upload it to migu music for China Mobile to take effect!
