Hello and thanks for researching this very important question!

Many dogs are accidentally poisoned each year when horse dewormer is administered off-label. These products are not FDA approved to provide dosages outside of those listed on the labels--there is no way to know how much active ingredient is in a smaller-than-labeled dose.

A 90 pound dog should not be given more than 272 mcg (micrograms) of ivermectin monthly. This is generally equivalent to just a "spot" of horse dewormer.

The neurologic symptoms you are seeing are consistent with ivermectin toxicity. Symptoms can get worse, and fatalities have been reported with horse-intended products.

Please take your dog and the package from the Zimectrin Gold to your nearest veterinary emergency service today.
