Mystery dog next door barking

Woke up
Mystery dog next door barking
Made carrot cake
Mystery dog next door barking
Ate carrot cake with friends
Mystery dog next door still barking
Pottered in the garden
Mystery dog next door still barking
Went for a walk with Brammle and Murron - returned home
Mystery dog next door still barking
As I type
Mystery dog next door IS STILL BARKING.
