Now Axle, my gorgeous cattle dog, will be 3 this year and he is very well trained. Now, whenever he used to bark, we would say "No!" and he would stop. But lately, he will just keep going and going and going, and he won't listen! He has never done this before! It's really weird because he is barking at nothing! I go and have a look, and he is just sitting there, barking! And I say "No, Axle, stop!" and he just keeps going!
Any idea why he is suddenly not listening? It's the first time in 3 years that he hasn't listened! And it's getting very frustrating, especially at 2 o'clock in the morning!
