My 12/13 yo (rescue but has been with us for ten years) JRT has started barking at night....for an hour at this stage tonight. We all (young adult dc and i) get up for work at 6am so being awake from three isn't ideal.
We think she's maybe slipping in her old age (evidenced in other behaviour) but is there anything we can do about the barking at night? She has been out (at 3am), has water and her comfy bed. Occasionally the kids have brought her up to their rooms but she just barks there too.
She has plenty of walks and company during the day. This barking has been an issue for about 6 months. We put her to bed after a short walk at 11pm. This has been her routine forever.
