Vaccination & De-worming Schedules
Boarder Pays for These Services
The following treatments are always at the expense of the boarder and should be
administered by the boarder, the stable staff, and/or a vet. The administrator of
these treatments will be specified in the boarding agreement.
Month Dewormer(s) Vaccines
February Ivermectin begin late winter or early spring –
Ivermectin Strongid EW encephalitis 1-2X/yr
(3 tubes) Tetanus - once/yr
Rabies - once/yr
Flu/Rhino - 2-4X/yr
West Nile Virus - 2X/yr
June one regular dose of any
dewormer or a larvacidal
treatment - see Dec
October Ivermectin Strongid 6 months after previous vax - Flu/Rhino
December Larvacidal deworming -
Panacur 10mg/kg (2 tubes)
daily for 5 days or Quest
1. These treatments should not be given on the same day but should be given in the same
month at least one week apart. The Strongid is to kill tapeworms; it is 2-3X the regular
Strongid dose; rec. 1-2X per year.
2. Larvacidal deworming is designed to kill all stages of equine parasites. A 2x dose of
Panacur over 5 days will do this. A regular dose of Quest will kill almost all stages. Two
larvacidal treatments per year is recommended on farms with lots of horses (> 20 in one
area). Otherwise, one is sufficient. Quest should not be used in thin or debilitated
animals, nor in foals less than 6 months of age.
3. Eastern and Western Encephalitis - Vaccination for encephalitis provides antibody for
about 6 months; it should be timed so that there are good antibody levels during
mosquito season. In years with long summers or if an outbreak of encephalitis occurs, a
booster for EEE and WEE is also needed in the fall. We recommend using the intranasal
influenza vaccine twice yearly. If traveling frequently or exposure to many new horses is
expected at home, vaccination for the rhinopneumonitis virus (both strains 1&4) is
recommended 4 times/yr.
If you wish to use the daily wormer (Strongid-C®) rather than an intermittent teatment schedule
as shown above, the horse must first be treated with a dewormer that kills encysted and migrating
larvae (Panacur or Quest as above). A boticide (ivermectin or moxidectin) must also be used
2X/yr, in the spring and fall.
