About PetDosageChart
About PetDosageChart.
A free, educational reference that helps dog and cat owners understand medication dosages, sourced from veterinary drug references and built to be transparent about what is checked and what is still pending review.
01
What PetDosageChart is
PetDosageChart is a free educational resource that provides medication dosage calculators, dose-by-weight charts, and plain-language safety information for common dog and cat medications. Our goal is to help pet owners understand the information their veterinarian works with, so they can ask better questions and care for their pets more confidently.
We are an independent reference site. We are not a veterinary practice, and using this site does not create a veterinarian-client-patient relationship.
02
Who it is for
This site is for pet owners who want to understand veterinary dosage information, not replace veterinary care. Our calculators give an educational estimate for a healthy adult pet at a known weight. They are a starting point for a conversation with your veterinarian, who knows your pet's full health history and can account for things a calculator cannot.
03
Our editorial mission
Accurate, transparent, source-based medication guidance for dogs and cats. We aim to be honest about what each page is: what is sourced, what is cross-checked, and what is still awaiting independent veterinary review. We would rather tell you a page is pending review than imply a level of oversight that has not happened.
04
How our content is created
- Dosage ranges come from established veterinary references, primarily Plumb's Veterinary Drug Handbook, the Merck Veterinary Manual, and FDA/DailyMed label data where applicable.
- We cross-check values against more than one source where possible, and we never publish a dosage number that is not drawn from these references.
- Pages are updated when the underlying references change. See our methodology for the exact sources and the math behind the calculators.
- Independent review by a licensed veterinarian is being added to pages over time, and reviewed pages carry a named reviewer byline.
05
Our review status (the honest version)
Many pages are still awaiting independent review by a licensed veterinarian. Those pages are clearly marked and rely on cited veterinary references. A named reviewer byline is added to a page only after a licensed veterinarian has reviewed it. We do not use generic "vet-reviewed" labels, because a review claim should always point to a real, named person.
06
Our reviewers
We are recruiting licensed veterinarians to review medication pages. Until a page has been reviewed, it will not carry a reviewer byline. To qualify as a reviewer, a person must:
- Hold a current veterinary license (DVM, VMD, BVMS, or equivalent).
- Have experience in companion-animal (dog and cat) medicine.
- Review against primary references and be credited by name on the pages they review.
