The aim of the present study was to determine wheter epidurally administered drugs are causing delayed hairgrowth, pruritus and urinary retention in dogs. Eighty dogs undergoing elective surgery of the pelvic limbs were randomly assigned to one of three groups: Group MB receiving morphine (0.1 mg/kg) and bupivacaine (0.5 mg/kg), group B receiving bupivacaine (0.5 mg/kg) and group S receiving saline solution 0.9 % epidurally. In a control group of 10 dogs (group K), the lumbosacral area was just clipped. Postoperativley first urination was noted. Follow up of hairgrowth started 4 weeks after the epidural anaesthesia by one blinded observer. Hairgrowth in the lumbosacral area was compared to hairgrowth in the surgery field. Pruritus was also noted. Follow-up examinations were performed every 6 weeks until hair had regrown or pruritus disappeared. There was an overall incidence of delayed hairgrowth of 10 in 80 dogs (12.5 %) 4 weeks after surgery. Seven dogs from group B, 1 dog from group MB, and 2 dogs from group S were affected. Pruritus was evident in 2 dogs (2.5 %) in the lumbosacral area. There was no statistical difference between the groups concerning hairgrowth, pruritus or first urination. The epidurally injected drugs were not related to delayed hairgrowth, pruritus or urinary retention in the present report. In conclusion it is unlikely that epidurally administerd bupivacaine or morphine cause delayed hair growth following epidural anaesthesia.
