The spellcasting ability used by boar companions is Strength. This gives a Difficulty Class for the  Prone effect of 9 at level 3, 13 at level 5, and 14 at level 11. The extremely low DC at level 3 is because the proficiency bonus of the beast companions is 0 until level 5 when it increases to 3.
Both  Elixir of Hill Giant Strength and  Elixir of Battlemage's Power will increase this DC. Animal companions and other summons can consume these items from the party's inventory.
