Like the others said, do not worry
If you were in Europe, everybody would say that is perfectly within standard. As Solo and Hiraeth said above, the breed standard for the FCI is 100lbs for females and 110 lbs for male lbs. The FCI is the "F*d*ration Cunologique Internationale", that has 91 members (1 for country), basically all world except Africa, Middle East and North America.
The AKC has a different standard (does not have a standard weight as BlackShadowCaneCorso mentioned).
There are historical reasons for that and all goes back to the 1980´s when the first CC were brough to the US. The biggest animals were picked and - at least in the beginning - size was one of the relevant factors in the breeding programs. That created very big CC.
So when the standard was stabilized by the FCI (CC were recognised on a provisional basis in 1996 and on a definitive basis in 2007) most of the north american cane corsi were out of that standard size. When the AKC recognised the breed in 2010 it opted not to have a size limit in order to include most of the existing north american CC
So, in fact, sizewise the north american CC may be very different from the others.
In my opinion if the FCI and the AKC don´t cooperate harmonizing the standards we may end up with a different breed (as happened with the Akita)
