Advancing monster

[jumpydady]

when we advance a monster by racial hit dice, do they get a stat bonus in every 4 lvls like a normal char? or they only get stat bonus when they increase size?

Only levels in a class generally bring stat bonuses, not racial HD.

If they have a mix of the two, it's up to you, but I'd be inclined to give it to 'em.

"Step 3: Ability Scores

Once you have determined the number of additional Hit Dice possessed by the creature, use this number to modify its other statistics. Start with ability scores. For every 4 additional Hit Dice gained by the monster, add 1 to one of its ability scores. In addition, make any modifications to its ability scores based on an increase in size, as noted on Table: Size Changes."

Every four hit dice, yes, per Justin Sluder's citation.
