Immediate steps should include the removal of substances from the gastrointestinal tract, adsorption, and catharsis. In case a dog is accidentally exposed to drugs during a search, police officers should have available apomorphine, syringes for administering drugs and rinsing the conjunctival sac, activated charcoal, a saline cathartic such as sodium sulfate, a resuscitator bag, and a well-fitting canine face mask. Immediate surgery by a veterinarian may be required if bags of drugs are ingested intact. Injectable medications to counter drug effects should only be administered by a qualified veterinarian, since pharmacologic antagonistic agents may have adverse side effects. The veterinarian should advise police officers on the proper use, dosage, and methods of administering detoxification agents, as well as on the proper use of face masks and resuscitator bags. Police officers should also be aware of clinical symptoms likely to result after exposure. Cooperation between veterinarians and police departments is essential in protecting dogs from chemical hazards inherent in their jobs. 14 references (Author abstract modified)
