in the past few days barkley (who is just over 2) has suddenly developed what seems like very nervous behaviour. it's not all the time but started with him suddenly glancing up at the sky frequently whilst out on a walk last week, to then not wanting to enter the kitchen over the weekend on several occasions, and now today he has spent much of the day glancing up lots at the ceiling, tail down whilst inside and out, being very clingy, and generally very tense. he's currently lying down on the sofa and would normally be pretty conked out. instead he keeps looking up suddenly with ears cocked, glancing around the room, leaning on me very heavily, following us if we both leave the room, tail always down.

he's not barking more than usual so it doesn't seem like a guarding thing, it just seems more 'nervous'. and the glancing up at the ceiling/sky is very out of character.
we're going to the vets later this week for annual booster and check-up so i'll mention it then but i just thought i'd run it by you guys to see if anyone else has had any similar experiences. sorry it's all a bit vague though...

thanks.
