I don't know what an Italian Mastiff is. His projected weight seems small for the Mastiff breed, as I have known them. I was in a dog training class witha Bull-Mastiff once. He was a really sweet dog and very tolerant of all the other dogs, but he had a mind of his own.
Different times of the day, he worked with different handlers -- Mom, Pop, child. One night class he was there with the wife of the family and the little boy. The woman was having a hard time getting the dog to sit straight after his "finish" where he is supposed to walk in a circle around his handler and then sit down facing front. He'd sit crooked, and you just couldn't move him after he was down.
The little boy called out to his mom across the room full of students and dogs, "Mom, just spit into your hand, and he'll follow you wherever you want him to go!"
We all got a good laugh out of that. But, you know that really works, as disgusting as it sounds! Out of the mouths of babes!
This Italian Mastiff, is characterised by the excessive loose skin and wrinkling on its head and face. Saved from oblivion by the Italian Piero Scanziani, it is becoming increasingly popular all over the world. But it is a large dog which needs plenty of food and early socialisation and training maybe necessary. It is also a drooler. The ears are cropped for cosmetic purposes only. It is an excellent guard of family and property. It does not demand heavy exercise.They may be grey, blue, tawny or black in colour. Brindling may also be present. It weighs 50-75 kgs and is 65-75 cms tall.
Sorry! I can't translate the kgs and cms into standard American measurements.
