Not a problem, the actual number of the weight should not really be as much of a concern as body condition is. Ideal standard weight for a female corso is only 85-100lbs and they should reach that size between 2-3 years old. My female was 77lbs on her 1st birthday, she just hit 17months and is 83lbs, slow steady growth and lower weights make for better joints and a longer more active life. I would like to see pics of her standing from the side, he ribs should be just visible in the right light
