The fastest way to wreck a healthy herd is to bring in one sick animal. Most serious herd problems, from footrot to resistant worms to abortion disease, arrive with newly purchased goats. This article shows you how to pick sound animals at the point of sale and how to run a simple quarantine so new stock cannot infect the rest. Follow it and you avoid buying someone else’s problem.

Why bought-in animals are the main risk

A goat that looks fine can carry parasites, footrot bacteria, or infections that only show up under stress or after transport. The seller’s herd may have built tolerance to problems that will spread fast in yours. This is why examination at purchase and isolation afterward are two separate, non-negotiable steps. Skipping either is where most keepers get burned.

How to inspect a goat before you buy

Watch it move first

Before you touch anything, watch the goat walk from a distance. It should move evenly with no limp, no stiffness, and no toe-tipping. Lameness at the sale point is a red flag for footrot or joint disease, both of which are hard to clear once in your herd.

Then do a hands-on check

• Eyes and eyelids: bright eyes; pull down the lower lid, pale membranes suggest worm-related anemia.
• Nose and breathing: no thick discharge, no coughing, no fast labored breathing.
• Jaw and neck: feel for lumps or abscesses; a soft swelling under the jaw can mean heavy worms.
• Mouth and teeth: check age and that the bite lines up so it can eat well.
• Feet: lift each foot, look for overgrown hoof, foul smell, or rot between the claws.
• Udder or testicles: check for lumps, hardness, or asymmetry depending on the animal’s role.
• Coat and skin: look for bald patches, scabs, or lice.
• Rear end: a clean tail area; staining points to scouring.

Ask the seller the right questions

Ask what the goat has been fed, whether it has been dewormed and with what, whether the herd has had any abortions, and why the animal is being sold. Honest sellers answer plainly. Vague or defensive answers are a signal to walk away.

Transport without adding stress

Transport itself weakens animals and can trigger illness that was hidden. Move goats in a clean, ventilated space, avoid overcrowding, keep the trip short, and give water and rest on arrival before handling them further. A stressed, dehydrated arrival is more likely to break with disease during quarantine.

Run a real quarantine

Quarantine means new goats are kept fully separate from the main herd for a set period, long enough for hidden problems to appear. A practical minimum is about three to four weeks.

• House new goats where they share no fence line, water, or feeder with your herd.
• Do chores for the main herd first and the quarantine group last, so you do not carry disease on your hands, boots, and tools.
• Observe daily for scouring, coughing, lameness, nasal discharge, and appetite.
• Deworm new arrivals on a vet’s advice and, ideally, confirm with a fecal egg count so you do not import resistant worms.
• Trim and inspect feet, and treat any hint of footrot before the goats ever touch your pasture.
• Only merge the groups once the new animals have stayed healthy for the full period.

A real example

A keeper bought four does at a good price and put them straight in with his herd because they looked healthy. Within a month, several of his own goats went lame with footrot, and worm burdens spiked. He spent a whole season treating feet and lost breeding time. The next year he isolated new stock for a month, checked feet on arrival, and had no outbreak. The only difference was the quarantine.

Common mistakes and how to fix them

• Buying on price and looks alone. Fix: inspect movement, eyes, feet, and ask herd-history questions.
• No quarantine. Fix: isolate every new animal for 3 to 4 weeks, no shared fence or water.
• Chores in the wrong order. Fix: always handle the main herd first, quarantine last.
• Importing resistant worms. Fix: deworm arrivals on veterinary advice and confirm effect where possible.
• Ignoring feet at purchase. Fix: lift every foot; reject or treat any rot before mixing.

Action checklist

• Watch the goat walk before touching it.
• Do the full hands-on exam: eyes, nose, jaw, feet, skin, rear.
• Ask why it is being sold and about herd abortion or lameness history.
• Transport clean, ventilated, and unhurried; rest and water on arrival.
• Quarantine 3 to 4 weeks with strict separation and last-in-chores order.
• Deworm and check feet before the animal joins the herd.

Conclusion and next step

Buying well and quarantining properly are the cheapest herd insurance you can buy. Before your next purchase, set up one isolated pen now, away from your herd’s water and fence line, so it is ready before the goat arrives, not after.

Frequently asked questions

How long should quarantine last?

Around three to four weeks is a practical minimum. That gives hidden worms, footrot, and stress-triggered illness time to show before you mix animals.

Can I skip quarantine if the goat looks healthy?

No. Many carriers look completely healthy. The whole point of quarantine is to catch what an inspection cannot see.

What is the single most missed check at purchase?

Feet. Keepers admire the coat and body but never lift the hooves, and footrot bought in this way spreads through a whole herd.

Should I deworm every new goat automatically?

Treat new arrivals on veterinary advice, and where possible confirm with a fecal egg count, so you clear their burden without blindly importing drug-resistant worms.
