I have read in several places that a player can cast Dragon's Breath (a 2nd level spell from Xanathar's) on their familiar. However, can your familiar use their movement while exhaling the magical energy? Specifically, could your Owl fly 15 feet above the floor/enemies and move 60 ft. around the battle map to target a line or group or enemies? Your owl would be exhaling in a downward direction (keeping the required cone shape) but creating a 15 foot by 60 foot area of damage.
Allowing your owl to in essence increase their AoE seems to overpower this combination. Can familiars use their movement while exhaling magical energy?
You can have your familiar fly around to position itself and breathe fire from a specific point, which is what they were referring to, but you can't have it strafe a larger area than the spell description says.

This idea was presented in a YouTube video from the Dungeon Dudes (time stamp, 4:15): https://www.youtube.com/watch?v=2t64EEUeNCc
