I totally agree with you there, Morgan. I understand it's routine veterinary practice to include an analgesic with the anaesthetics they use for animals, but this will wear off after 12 - 16 hours. My Vet told me aspirin is quite safe for dogs, & doesn't have any of the side-effects it causes in humans, so I give mine the aspirin/codeine meds we can buy OTC here - they certainly seem to appreciate it & be more comfortable after a dose (obviously adjusted for their particular body weight).
