I dont know if anyone can help but my sister has a nearly 3 year old golden cocker spaniel, who up until last week has always been very good at bedtime & in the morning however the last week or so he has been howling at night & early in the morning. It seems that if he wakes up during the night instead of going back to sleep as he always has done, he now howls & barks until someone gets up to him.
Just wondered if anyone could shed some light on why he maybe doing this?
