Ive seen so many variations in the breed of recent years. Its what line you go for. In serbia they brees lines like mastiffs in some places that are 150lbs plus. You can also get some that are very small. My last male was 75lbs. So you get both extremes and anything inbetween, as well as overwight/underweight/byb etc. My male i have now is ADRK line which are very strict on their standards and perserve the breed to strict criteria. All dogs are fully health tested including heart and eyes. All dogs in line are titled bh, ch, ztp multi v rated etc and as for weight again, they are all within standard. Its what you prefer and are looking for. The breeding has been varied so much in recent decades there seems to be no "one size fits all"
