Once they reach about three month or so, that average growth rate is about ten pounds per month - give or take a pound or two. At seven months, Romeo one of our males was 77 lb. and maxed out at a little over 100 lb. That is the average size for the males in his bloodlines.
Females average slightly smaller.
The weight at different ages can vary widely from one pup to the next. Based on several factors including bloodlines, nutrition, exercise, etc and general over all health. Lots of exercise is good, but the Dogo does not require 'excessive' amounts, no more so than similar breeds.
