Tapeworm treatment for dogs entering the UK: the 24-120 hour rule

Last updated: September 9, 2026 — verified against GOV.UK and USDA APHIS.

The UK is free of the tapeworm Echinococcus multilocularis and keeps it that way at the border. Every dog entering the UK must receive a tapeworm treatment administered by a vet between 24 and 120 hours before arrival. The window is enforced: too early or too late, and the treatment does not count.

The rule in 3 points

Dogs only. Cats are exempt from the tapeworm requirement entirely.
Administered by a vet. The treatment must be given by a veterinarian, who records it on the animal health certificate with the date and time.
24 to 120 hours before arrival. Count backwards from the moment your dog lands in the UK. The same window applies whether you come from the USA, the EU or anywhere else.

Too earlyOver 120 hoursTreatment given more than 5 days before arrival does not count

The window24 to 120 hoursThe vet visit must fall inside this window before UK arrival

Too lateUnder 24 hoursTreatment on the day of arrival is too recent to count

Practical planning

Book the vet appointment after your flight schedule is locked, and aim for the middle of the window rather than the edges. If your flight is delayed and you arrive outside the window, expect the treatment to be redone at the border or your pet to be held. The vet must note the treatment on the AHC, so the appointment and the certificate issue usually happen together.
