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.
With regard to companionship, it suggests that dogs should not be left alone for more than four hours a day depending on their age. However the survey revealed that 23% of respondents left their dog alone for more than five hours a day on a typical weekday. Most dogs sleep in their own beds at night and so are probably left alone for 8 hours a night. However 17% of owners allow their dogs to sleep in family beds. So we know that dogs can be left 8 hours at night but the PDSA are saying that if you leave them for more than four hours during the day, you are compromising their welfare.
