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.
Itâs recommended that four hours is the longest that dogs should routinely be left alone for. Every dog will be different, dependant on how old they are and what they are used to. For example, four hours would generally be too long for a very active, young puppy. Boredom can cause dogs to bark or be destructive in your home. Try to think about how long your dog would routinely need to be left alone, before you get one. If you work long hours, a long way from home, a different pet might suit you better. If you know you will regularly need to leave your dog alone there are some things you can do to help your dog.
