Is anyone reading the news box?
if shes 6 months and 70 lbs you are doing way fine. Also keep in mind depending on your dogs bloodline they could still have a lot of growing to do up to 2 years old. One of the other members of this board mentioned that her female grew 4 inches after she was a year old. Mastiff breeds tend to grow slowly and for a long time from what I've been told.Here is a chart that has an average growth rate in kg. just google a metric converter and plug it in.http://cane-corso.misto.cz/_MAIL_/English/en_info.html
