The animals it covers

Every condition is tagged to the animals its source names. Pick one and the sign index opens already narrowed to it.

Counts are conditions carrying clinical detail for that animal. Dogs and cats appear because the drug handbooks cover them; the disease index is a large-animal one.

How to read an entry

Every drug and every condition is set out the same way. The entry below is real: the dose, the withdrawal time and the citation are the ones the app carries for oxytetracycline in cattle.

Oxytetracycline

Tetracycline-class bacteriostatic antibiotic


Animal Cattle
Dose 11 mg/kg q12h IV — injection for anaplasmosis, enteritis, pneumonia and other infections.
At 350 kg 3,850 mg per dose
Withdrawal Cattle, injection: 18–22 days for meat, depending on the product. Milk: 96 hours at 20 mg/kg.
Source Papich Handbook of Veterinary Drugs, 5th Edition (p. 689)

The animal decides the number. Doses are matched to the species the book published them for. Where a book gave no dose for your animal, no number is shown — not another animal’s.

The weight resolves it. Enter the body weight once and every rate in the guide becomes an amount you can draw up.

Withdrawal is never buried. Milk and meat times are marked on the entry. Where the books say nothing, it says so — silence, not clearance.

The page is always there. Book and page on every clinical line, so you can check it against the shelf.

What is in it

What it will not do

The limits are the point. An app that answered past its sources would be inventing clinical judgement and dressing it in the same cited styling as everything else.

It will not predict an outcome. Whether the animal recovers depends on efficacy, resistance, stage and the individual — none of which appear in any of these books. The review checks a plan; it never forecasts one.

It will not show anything it cannot cite. No line appears without its book and page. Where the sources are silent, it prints that in those words.

It will not guess a dose across species. A dog dose is never quietly offered for a cow. Buffalo borrows cattle’s doses because that is what a vet does, and says so on screen.

It is not a diagnosis. It is an index to a shelf of textbooks, ranked by the signs you gave it. The clinical judgement stays yours.

Built to work with nothing

Install it once on the phone and it runs with no signal, no account and no server — the whole index, every dose figure and every citation stored on the device. Nothing you type leaves it.

In Chrome or Edge, use Install in the address bar or the browser menu. On an iPhone, open it in Safari and choose Share → Add to Home Screen. On Android, Menu → Add to home screen. It can also be unzipped to a phone or laptop and opened straight from the file, with no server at all.
