The signs of successful pregnancy in dogs are as follows:

Nipples become red and swollen: The earliest sign of dog pregnancy is usually nipple changes. Redness and swelling, but this redness is pinkish in color and usually begins to appear 2 to 3 weeks after conception.

Getting fatter and gradually protruding belly: Dogs usually start to gain weight at 4 to 5 weeks, and at the beginning, their waist only becomes thicker and their belly becomes slightly swollen.

Lethargy and inactivity: As the dog’s pregnancy belly gradually grows larger, it begins to have difficulty moving, and as it is unwilling to move, the time it takes to sleep becomes longer and longer every day.

Eating less and less: In the last few weeks of pregnancy, the dog’s uterus becomes larger and larger, occupying a large part of the abdominal cavity, so the appetite will be affected accordingly, but it does not. It’s not about not eating, it’s about eating small amounts and frequent meals.
