forgo size increase and stat blocks for animal companions

[Outland King]

the question I have is, if I have a wolf animal companion, once it gets to 7th level the following adjustments occur.

Wolf

Starting Statistics

Size Medium; Speed 50 ft.; AC +2 natural armor; Attack bite (1d6 plus trip); Ability Scores Str 13, Dex 15, Con 15, Int 2, Wis 12, Cha 6; Special Qualities low-light vision, scent.

7th-Level Advancement

Size Large; AC +2 natural armor; Attack bite (1d8); Ability Scores Str +8, Dex –2, Con +4.

if I decide to forgo the large size adjustment in favor of the Dex and Con boost, do I still apply the other stat adjustments or do I ONLY apply the dex and con boost?

so would the final stats be 21,15,21,2,12,6 or would they be 13,17,17,2,12,6

It's either / or.

Instead of taking the listed benefits at 4th or 7th level, you can instead choose to increase the companion's Dexterity and Constitution by 2.

never seen that ruling... anyone can provide a link?

It's in the Druid class features, in the paragraph that prefaces your Animal Choices.

Ah. There it is.
