Whitewave - what do you mean 'one dog is enough'? I've been know to have three, I don't mean mine and foster or visiting dogs, I mean my own, much loved, messy mucky hairy dogs.
Currently I'm down to two and I do believe I've reached a stage in my life when that is enough. Especially as youngest's dog often moves in, mysteriously and for periods that stretch from the overnight requested....
All my dogs have told the time. When the girls were due home on the school bus, our old rescue boy would go and sit at the middle of the stairs, the best vantage point for spotting the bus arriving. He'd pop himself there about 5 mins before they were due. He also mysteriously knew when Mr iam's care was 5 mins away, despite the fact his schedule wasn't to a time table like the school bus.
As for dogs knowing the time for walks, feeds etc - clockwork.
