A technique for saliva collection in dogs

A plastic two-chambered vacuum-collection device was developed to collect saliva produced by the parotid gland in dogs. Repeated application of the device on the parotid gland papilla was atraumatic. Dogs were restrained during the collection period with a continuous intravenous infusion of ketamine hydrochloride and diazepam in lactated Ringer's solution. The anesthetic regime did not interfere with salivation.
