Comparison
ExoticRx vs Plumb's: An Honest Comparison
We built ExoticRx because we couldn't find a drug-dosing reference that took exotic-pet medicine seriously. Plumb's is the gold standard for small-animal practice — but it isn't built around reptile, avian, pocket-pet, livestock, or equine cases. Here's how the two compare, written by people who use both.
TL;DR
- Choose Plumb's if your practice is >90% canine and feline and you want the deepest small-animal monographs available, in print or online.
- Choose ExoticRx if you see exotic species, you want every dose rule individually graded by evidence strength, and you'd rather pay $99/yr for a tool that updates continuously than $149/yr for an edition-cycle reference.
- Many clinicians use both. The free tier of ExoticRx covers dog/cat dosing for evaluating it alongside an existing Plumb's subscription.

When Plumb's is the right choice
- · Your practice is small-animal-only and you value the encyclopedic depth on canine and feline pharmacology.
- · You want a print reference that lives next to the exam room — Plumb's remains the best at this.
- · You're training residents who need exposure to a comprehensive small-animal monograph format.
When ExoticRx is the right choice
- · You see reptiles, birds, pocket pets, livestock, or equine — even occasionally. The exotic-pet appendix in Plumb's isn't built for primary reference.
- · You want to see which study a dose came from, not just whether one exists. Per-rule citations matter more than monograph length.
- · You want every dose graded by evidence strength so you can apply weight to STRONG findings differently than to EXTRAPOLATED-from-canine-data.
- · You'd rather your reference update continuously than wait for the next edition.
- · $99/yr vs $149/yr is a $50/year saving on a tool you'll touch dozens of times per week — and the free tier is a real evaluation path before you commit.
