A 13-week-old female mastiff typically weighs between 25 to 40 pounds, depending on her genetics, diet, and overall health. It's important to monitor her growth and ensure she is gaining weight steadily. Regular vet check-ups can help assess if she is on track for her breed's growth standards. Proper nutrition and exercise are also crucial during this stage of development.
