IV a 10 month old golden retriever who barks at home and it's usually from about 830pm onwards, he seems to have gotten worse due to the dark nights. He tends to bark when looking out of the windows, like when lights go on or people walking past. He doesn't bark on walks or much during the day and never barks in his crate, it's just when something spooks him outside and its when we are home, not when he's on his own.
Any tips or advice on how to help stop him barking would be much appreciated as once he starts, he forgets to stop.
