Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
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.

Need the exact dose for your patient?
These ranges are per kg. Enter your cockatiel's weight to get the precise dose and draw-up volume — unit and concentration math done for you.
Inhibits protein synthesis by binding to 30S ribosomal subunit, preventing aminoacyl-tRNA attachment.
Can cause esophageal strictures in cats if not followed by water. Photosensitivity. Avoid in pregnant animals (tooth discoloration in fetus).
Species-specific contraindications and adverse-reaction reports for cockatiels may differ from canine / feline reference data — consult the primary citations listed with each rule.
Doxycycline dose ranges in cockatiels, with cited source references: IM 75–100 mg/kg q5-7d x 4-6 wk; PO 25–35 mg/kg every 24 hours. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Doxycycline in cockatiels: IM, PO.
Doxycycline is indicated in cockatiels for: Avian chlamydiosis (Chlamydia psittaci infection).
These are general warnings for Doxycycline across species; consult the cockatiel dosing table above for species-specific guidance. Can cause esophageal strictures in cats if not followed by water. Photosensitivity. Avoid in pregnant animals (tooth discoloration in fetus).
Why a species-specific page? Doxycycline pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cockatiels — the rules above are the citations specific to this species, not generic recommendations.
