I have an 18 moth old Staffy X who I have had for just over a year. I moved house 3 weeks ago and he has suddenly started barking. He's never been a noisy dog and he doesn't bark all the time, only when it's dark outside. He tends to growl for about a minute then goes to the back door and barks. When I let him out for his last toilet before bed, he barks outside. When he comes back in he is quiet, but when I go uo to bed, he barks again for a couple of minutes and goes to sleep.
Does anyone know what might be causing it? I have been checking outside and there hasn't been anyone in the garden. My sister has joked about mum coming back as a ghost!
He's as regular as clock work with the barking and doesn't bark at any other point during the day....help!
