How much the weight of 2 month rottweiler puppy?

It is quite hard to answer these type of questions, as all rottweilers are different depending on their lines. Females weigh slightly less to male so she should be anything between 90 - 110lbs. Don't forget that rottweilers are still building their muscle tone up and are still putting on pounds until they are around 3 - 3 1/2 so don't worry. Try not to over feed her, there is such a stigma about having a beefy rottweiler, she will reach her optimum weight.
