I am almost positive that the English Mastiff is the largest breed of mastiffs. Correct me if I am wrong. My boyfriend wants one && swears that it is. They get anywhere from 100-200lbs. A pretty large breed.
Yes it can,But if you have a cane corso mastiff i wouldn't breed it to a american,english,or pyrenean mastiff because those types of mastiffs are the largest of all mastiffs. ;)
Well alot of people believe it is a grate dane but, it is a Irish WolfHound. Right now a grate dane is the larges dog its the only one and not a species it is just a dog that is bigger it's a dog...
