Me and my girfriend moved in to a new apartment few months back and she owns the terrier who is 5 yrs old now. I've never lived with a dog, I've owned a cat for 15 years so lots of stuff were pretty new to me. I had to learn many things which I applied with great success, there's still lot to learn but there is steady progress every few days.
The main issue we have at this point is that at night, and only at night, it's as if he's only waiting for an opportunity to bite me. We had few situations like this already like I would sit calmly on my chair, maybe on my laptop or phone and the dog would be either asleep or just laying down. As soon as I would make even the slightest noise or movement, for example closing the laptop or getting up, there he is lunging at me.
During daytime he's pretty good, playful, submissive if told, quite normal behaviour.
Any idea what could be causing this behaviour?
