Medetomidine, either 5, 10 or 20 (μg/kg, was administered together with pethidine, 2 mg/kg, by either the intramuscular or subcutaneous route to 88 dogs from a clinical population. Administration of all the drug combinations consistently produced profound sedation in the dogs, accompanied by dramatic reductions in heart rate. The degree of sedation was similar to that seen after 40 μg/kg medetomidine is administered on its own to dogs. Intramuscular administration produced more reliable sedation, but was associated with more pain than subcutaneous administration. In a number of dogs, sedation permitted the completion of various diagnostic or therapeutic procedures. Several dogs were anaesthetised with thiopentone and the induction doses required were characteristically low (mean doses between 2 to 3·3 mg/kg depending on the dose of medetomidine and the route of administration). Administration of atipamezole at the termination of sedation or anaesthesia, produced a rapid and full recovery (mean time to standing between seven and 11 minutes).
