Sometimes there isn't a thread specific enough to prompt telling your favourites... so here's a free-for-all!
Favourite stories about your dogs: past or present, funny, sweet, sad, creepy... anything goes!
Mine's potentially outing, but...
Working on a horse ranch in Wyoming, one of the horses got very sick and went downhill fast. Vet was a long way off with another patient, but said he'd be with me as soon as he could.
Horse was lying on the ground with his head in my lap (as I sobbed) in between seizures, and at some point I looked up to see every dog from the farm (8 in total) sitting or lying in a semi-circle around us, watching.
After about 30 minutes, with no prompt, they all got up and left. I took it to mean they could sense he was about to pass on – but 5 minutes later he was back on his feet.
I now believe he received some kind of energetic power-up from the pups – when the vet arrived he couldn't believe his eyes.
Those dogs all got extra treats that night

Lightening the mood a little, another favourite of mine is the time my childhood dogs mysteriously adopted a duckling.
To this day none of my family have the slightest clue where it came from – my mum opened the back door one morning to give them their breakfast and out of the kennel came our two black Labs with a little duckling tumbling out between their legs and following them into the kitchen!
They were best friends for years...
