> he gets very stressed if out of his normal routine
Oh how I know the feeling! We're having a kitchen fitted and poor Buster is not pleased with his routine being changed, even though he usually just lollops around on the sofa all day he usually has the freedom to wander. He's not liking being shut in the living room, he has this thing where he must watch his water being topped up fresh at the sink and is really not liking not being able to supervise the 'filling of the water bowl'!
Bless him, although he's been calm the entire time, the first few days he was trying to force himself to stay awake and he just couldn't keep his eyes open any longer & nodded off while sat up. I think it's from his instinct to be keeping an eye on strangers and he's actually less settled with me in the room with him (he likes to keep watch over me I think).
He had some respite over the weekend, with the fitter not coming back 'till yesterday but he found it very tiring again, to the point he didn't even want to go on his full walk - he wanted to get back home. I'll be sooooo glad when they have finished the kitchen and so will Buster. He isn't stressed as such,, he even greeted the workmen with a waggy tail & a happy dance this morning, but he'd much rather have nothing to think about and be sending up the z's on the sofa in peace.
Poor dogs, creatures of habbits get unsettled when their habbits are suddenly changed. (LOL, I'm the same, I want things back to normal NOW!!!!! before I go 'round the bend!!)
I hope you find something to help your dog.
