Hi, thanks for using Petcoach! Fierce is beautiful! based on your pictures she looks like a healthy puppy! The weight of dog is based on it's bone structure. Not all dogs within the same breed will weigh exactly the same. Just like people. Fierce has a lot of growing still to do. She may be a more petite Rotweiller, which is perfectly fine. We want her to be a good body condition, over feeding her could lead to obesity which is a health issue. You want her to just be healthy! I've attached a body condition chart to help you figure out if she is an ideal body condition score. https://oregonvma.org/files/Purina-Dog-Condition-Chart.pdf I hope this eases your mind!

    Hello and welcome to Petco Pet Education Center, formerly Petcoach. It looks from your image that Fierce is a fine size. All dogs will vary in size depending on the size of their parents, their bloodline, and just individual variety. Also, it is important for large breed dogs to grow slowly to help prevent 'growing pains' and issues with their joints. As long as she is happy, playing, eating, and having normal poops then don't worry. Feed her a good quality large breed puppy food, and don't worry about her not growing fast enough, she will get there. Trying to get her to grow faster may lead to joint issues, so avoid this. Best of luck with Fierce and have fun with her.
