CARBON MONOXIDE VERSUS SODIUM PENTOBARBITAL COST ANALYSIS WORKSHEET
DIRECTIONS: The analysis below uses data from an actual municipal animal control agency. To determine your cost, insert localized data where appropriate.
Note: The current standard for CO euthanasia requires a backup method (typically sodium pentobarbital) for animals less than 16 weeks of age or sick. Although the cost of backup adds to the overall cost of CO and is not calculated in this model, this additional cost would be partially offset due to fewer CO cycles necessary (thus less gas/labor costs), since some animals will be euthanized using the backup method.
Original model prepared by the Humane Society of the United States Great Lakes Regional Office, based on the Animal Euthanasia Cost Analysis Work Sheet developed at Texas A & M University November 1991.

Add the cost of acepromazine maleate (.5 mg./pound) plus needle and syringe.
Approximate cost for 50-pound dog:
$0.27 ´ 5100 dogs (approximate # to be put into chamber) = $1377.
