Question: how long can i leave a 4 month old puppy alone?
Answer: 3 month old puppies can wait for 3 hours, 4 month old puppies for 4 hours, and so on. After 6 months: An older puppy, like most adult dogs, has the ability to hold it in for up to six hours. If you don't have a dog door, be sure to pop home at lunch or get your pet sitter to pay a visit if you're unable to do so.
