Six people died earlier in the week after eating the barbecued carcass of a dog believed to have been found by a roadside.
Four others from the same remote village in the Kratié (or Kraches) province in the northeast of the country later died after consuming the meat as well as drinking rice wine on Tuesday.
The deaths began on Sunday after a 76-year-old man died several hours after cooking and eating the dead dog.
In a zen-like twist, guests at his funeral, which was held the following day, also ate the leftover dog meat and were rushed to the hospital with acute food poisoning.
The deaths are in region of Cambodia where canines are regarded as a delicacy.
