It is difficult to give you an exact weight that Rosie should be without seeing her and knowing how big her parents were full grown. She may be anywhere from 60-90 pounds by now. The key it to make sure she is on a large Breed puppy food and she is a healthy weight. This means when you look st her you can see her ribs but you can easily touch her and feel her ribs. Also, you should be able to appreciate a “waist” when you look at her from above and the side. If you don’t see a waist, she may be too heavy, but it is unlikely a puppy with become overweight. If you google “dog body condition chart”, several charts will come up that will help you decide if she is the proper weight. I hope this helps!
