For the health and well being, you should not leave your pet home alone too long. Adult dogs (those over 18 months of age) can be left alone four to six hours a day. Young puppies should not be left alone for long periods during the day â around two hours a day is the limit.
No, a dog cannot stay alone 12 hours. It is very difficult to ensure the physical safety and comfort of one or several dogs that stay unsupervised that long, and from a mental point of view it is of course totally unacceptable.
