Google has starting dogfooding Android 4.4.3, according to the buzz around the virtual water cooler. For those who think that we are talking about Alpo, or Snoopy's famous suppertime dance, it is actually a term that means the new OS build is getting tested internally at Mountain View. Currently, the testing is being done by 1% of Google employees who work outside the Android team, according to the most recent rumor.
Current "dogfooding" is limited to the Nexus 4, Nexus 5, Nexus 7, Nexus 7 (2013) and the Nexus 10. Google Play edition models and the Motorola Moto X will soon join the action.
Once the dogfooding expands to more than 1% of non-Android Google employees, and there are no major problems reported, it will be ready for the public to receive it via an OTA update. By the way, Google says that Android 4.4.3 contains "critical security and stability" fixes.
