Companion Animal Euthanasia Training Academy Oral and Injectable Pre-Euthanasia Sedatives/Anesthetics for Dogs and Cats Compiled in 2017 by Dr. Kathleen Cooney, U.S. CAETA instructor Disclaimer: These protocols are meant to provide options for sedation or anesthesia, ranging from mild to deep planes of sleep. Intraorgan injections are only permissible during periods of heavy sedation or anesthesia wherein the animal is pain-free and unaware the injection is occurring. When in doubt, CAETA recommends more drug be given to ensure a pain-free death. Giving sedative or anesthetic drugs to frail and compromised animals can result in adverse reactions or death itself. Drug and drug combinations can be administered intramuscular(IM) or subcutaneous (SQ) unless otherwise specified. Oral drugs may not elicite the desired depth of sleep every time. Many factors affect rate of absorption and uptake. Higher doses may be given initially or when it becomes clear the pet requires more. Dr. Cooney’s Injectable Protocols (IM and SQ) Dogs Sedation protocol (SQ preferred) • Dexmedetomidine (0.5mg/ml) = 0.1 ml per 10# minus 0.1ml (can decrease total by 0.2mls over 50# bw) [can substitute with Xylazine (100mg/ml) = 0.1ml per 10#] • Nalbuphine (20mg/ml) = 0.1 ml per 10# or Butorphanol (10mg/ml) = 0.1 ml per 10# • Acepromazine (10mg/ml) = 0.05 ml per 10# Anesthesia protocol • Telazol® (100mg/ml) = 0.1 ml per 10# • Acepromazine (10mg/ml) = 0.1 ml per 10# • Xylazine (100mg/ml) = 0.025 ml per 10# Cats Anesthesia protocol • Telazol®* (100mg/ml) = 0.15 ml for 2-5# 0.25 ml for 5-10# 0.3 ml for 10+# • Acepromazine (10mg/ml) = 0.1 ml for all BW Anesthesia protocol • Alfaxalone (10mg/ml) = 1.1 -1.5ml for most cats • Nalbuphine (20mg/ml) = 0.2ml for all BW • Acepromazine (10mg/ml)=0.1ml for all BW BW = body weight # = pounds mg = milligram ml = milliliter Various Other Injectable Protocols Shared by Veterinary Colleagues, compiled in 2016 Dogs 1.
