Yes, but dichlorvos has also been used as an equine anthelmintic. Granted,
it has been largely replaced by more effective products with a higher
margin of safety, but let's not get overly frightened of the stuff.

	The collars marketed expressly for tick protection contain amitraz, which,
used topically on horses (as a "dip") has been fatal. They are more
sensitive to it than dogs.
