Older Dog has started barking at night

I hope the Dorwest things help, we also have the tree barks powder & have only had to use it once so far luckily but it worked quickly, so it's a good one to have on hand I feel.
It is distressing to see them poorly & confused, it happened to one of my dogs a few years back, not the night barking but the 4am waking and wanting to go out and sit in the garden was something he liked to do all of a sudden. Other times he'd go and spend time outside and then come indoors to do his business. I never told him off, I just cleaned up without a word and then gave him a cuddle,because he couldn't help it & needed re-sassuring. Give your lovely dog a cuddle from me, I hope things improve for you both soon .

Good luck maya1, so very hard to watch our beloved doggies getting old and infirm, just heartbreaking but we love them dearly xx

Good luck Mayal, I wish I had a magic wand for all of our pets. Your dog is lucky to have you.

Thank you highlanddreams, Susysue, Shandy57,
Finn is getting extra cuddles and being told what a good boy he is. It was 2.30 am this morning when l got a big wet kiss and a nudge to say wake up mum, l want to go out.
Just taking it day by day because as you all say what else can l do.

Many years ago we had a Bouvier des Flandres, Zeke, who started barking at night (he was 12). Tried a few things with no success, then I thought I'd try a light. Had a plug-in security device that switched a socket on if there was noise - plugged a light into that and success! He'd obviously become scared of the dark, maybe with a reduction in sight (never displayed any loss of sight but would make sense). So maybe leave a night light on?

Mayal - what a lovely dog owner (if you consider it owning) you are. Will keep fingers crossed for you.
Markulous - what a beautiful dog . I have never heard of that breed.
