Meant to add that once they've settled they lie and sleep together and sleep together at night so long as it's not me that settle them down. They all enjoy their walks together and run around on their own or together in a pack. When things kick off the other two dogs just get as far away as they can. There are no other niggles with each other. The eldest is sprightly for his age but I also think he has slight blindness although the vet said not. At times it's as if he has to scent another of the dogs before he cand stand down.
