[Ivermectin: dangerous for dogs].

Given that the National Poisons Control Centre is regularly contacted about ivermectin intoxication in dogs, we would like to emphasize the warning of Nap et al. (4) that the use of ivermectin in companion animals, and especially Collies and Bobtails, is not without risk. For this reason, the 'off-label' use of ivermectin for these dogs is not advised. There is currently a wide choice of selective drugs for the treatment of canine parasitic diseases.
