Deworming Rotation and Sprint/Fall Shots Schedule

Tetrahydropyrimidine/Benzimidazoles/Ivermectin: Because internal parasites (worms) in horses can build up a resistance to dewormers after repeated use, and because different dewormers have different levels of effectiveness against certain worms, equine veterinarians recommend rotating classes of dewormers, that is, using different chemical classes.  Since reinfestation is difficult to control, most veterinarians recommend deworming horses every two months.  This information was taken from Wiese Equine Supply 800-869-4373.

SHOTS: Spring: 4-way vaccination against Eastern and Western equine encephalomyelitis, tetanus and influenza/flu.  Fall: influenza/flu and strangles.  Veterinarians may alter combinations for current conditions.

You can skip a paste worming during the spring/fall seasons when the shots are given.  Spring and fall shots and tube worming can be done by your veterinarian or by Chapparal Animal Hospital (602-992-4700).

SAND COLIC: For the first seven days each month, we suggest you give your horse 99% pure psyllium hydrophilic mucilloid such as Equi-Aid, Mucil-Lax II, Natural Fiber Supplement (NFS pellet), etc. to aid removal of sand from the intestinal tract and to help prevent sand colic.
