Yes, you can leave your dog alone with her puppies. It’s just important that you keep in mind certain things before you make such a decision. Make sure that your dog is comfortable around other dogs and other pets. This is especially true when they are young and inexperienced. Ensure that the area where the puppies live is safe and free from hazards. You want to make sure that your dog does not get hurt or injured by something. Check on the puppies often and ensure that they are feeding well and have enough water. If you think that they might need more than what they are getting now, give them more. If you cannot take care of the puppies, then find someone who can. There are many websites offering puppy-care services. Give the puppies time to grow. It takes up to two years for a new puppy to become fully mature. So, don’t expect them to behave like an adult dog right away. Don’t allow strangers to come into their home without permission. They could potentially harm your dog and/or puppies.
