Charges levelled against trainer Con Karakatsanis and his father Tony over a breach of raceday rules will be heard next month.

Racing Victoria stewards issued a total of five charges against the pair for attempting to treat the smart sprinter Howmuchdoyouloveme before it ran on the opening day of the Melbourne Cup carnival.

Stewards found a bag containing naso-gastric tubing equipment in Howmuchdoyouloveme's box during a stable raid.

Tony Karakatsanis, a licensed stablehand, admitted to stewards that he placed the bag in the horse's stall but said he thought it contained hay.

Howmuchdoyouloveme was permitted to run in the Yellowglen Stakes at Flemington on Victoria Derby day but finished down the track.

The Racing Appeals and Disciplinary Board will hear the matter on January 7.
