The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.

Cross-extrapolation from canine doses is unsafe in lovebirds — the rules above are the citations specific to this species, not generic recommendations.
