When a dog reaches the four-week mark of her pregnancy, her body starts to show some pretty fascinating changes—especially in the nipple department. Those little nubs are gearing up for the main event, and it’s not just a fashion statement. It’s nature’s way of preparing for the adorable puppies that are on their way.

Understanding Dog Pregnancy

During pregnancy, a dog’s body undergoes significant changes to support her developing puppies. Starting in week four, noticeable transformations occur, particularly in the nipples. Nipples may appear larger and darker, reflecting hormonal shifts that prepare the dog for nursing.

Body weight typically increases as a result of developing puppies. A veterinarian might assess weight gain during routine check-ups to ensure the dog remains healthy throughout her pregnancy. Growth of mammary glands begins, facilitating milk production. This process can vary among dogs, depending on factors like breed and overall health.

Pregnant dogs may exhibit behavioral changes as well. She might seek more attention or display nesting tendencies. These actions signal her instinct to prepare for motherhood. Increased appetite often accompanies this phase, as it supports both her energy needs and puppy development.

Monitoring the dog’s physical condition is crucial during this time. Signs of distress or discomfort warrant immediate veterinary attention. Proper nutrition plays an essential role in maintaining her health and that of the puppies. Nutrient-rich diets promote optimal growth and development.
