what's the procedure to put an elderly dog to sleep?

[siabm]

I don't mean as in how they do it, but when you realise your elderly dog is at the end and make a vet appointment, do they do it there and then or ask you to come
back?
Over the weekend, my almost 16 year old
girl has gone completely downhill. She's been sleeping lots lately and not wanting walks so just pottering in the garden. She's drinking lots of water but refusing all food now, (since yesterday) and even her favourites like roast chicken and sausages.
She's now struggling to stand up and walk and I've been lifting her in and out of house to have a wee.
I'm going to phone at 8am when vets open, but can't imagine they'd want to do tests on a dog this age. She's on vetmedin for a heart condition too and has been since she was 9.
I just feel it's obvious she's reached the end now.
Can we all be there in the vets when she goes? My adult daughter
and 12 year old want to be there. Will the vet agree to this or want just one of us there?
I'm heartbroken 😢😢🥺😔

Thinking of you today @siabm ❤️

@siabm and anyone else who goes through this, please dont be embarrassed by crying in front of the vet. I had two dogs PTS at home a year apart, and each time the vet and her assistant were amazing, handing me kitchen roll as I sobbed and snotted my way through the whole thing. When they left I apologized and they said it was "lovely to see a dog so loved that her loss created such emotion" (or something like that!)

we took her this morning.
It was quick and peaceful.
We all sobbed. The vet cried too (and was absolutely lovely)
It hurts, but I know we did the right thing.
When she passed I had a huge wave of grief alongside a huge feeling of relief, that she's been set free and isn't suffering now.

Phone the surgery and the reception desk will talk you through, they do it differently so I can't tell you for sure. Ours came to the house if you wanted to bury at home which was so good of them, didn't charge extra either.

@siabm - you did the last kindest thing you could do for your DDog, she’s up there in doggie heaven, look for the brightest shining star tonight, that’s her telling you she’s ok.

aww, that's so beautiful, I will do that xx
