Not all individual dogs in the breeds listed above carry the mutant gene. doi: 10.1016/j.cvsm.2011.12.005.Am J Vet Res. Wright HM(1), Chen AV, Talcott PA, Poppenga RH, Mealey KL. Sensitivity to the drug can also be seen in dogs or puppies that have overdosed on a similar medication in the past. 2012 Mar;42(2):313-33, vii.

Ivermectin prevents or kills parasites by causing neurological damage to the parasite, resulting in paralysis and death for the … Although the combination, but not ivermectin alone, produced a significantly higher total Mazzotti reaction score than albendazole, the clinical significance of this difference was minor. Lovell R A (1990) Ivermectin and Piperazine toxicoses in dogs and cats. This toxic reaction occurs especially in dogs that are genetically hypersensitive to ivermectin, an anti-parasite medication most commonly used for heartworm prevention, or to treat ear and hair mites, which can lead to mange. Other sources of information. Toxicity results in any number or combination of clinical signs ranging from mild to extremely severe, including death. Mild ivermectin toxicosis developed in one dog after 5 weeks of treatment; side‐effects resolved shortly after the treatment was stopped. At higher doses (e.g., 5 mg/kg), we can see signs of ataxia, tremoring and seizuring.

Note that in normal healthy dogs, the LD50 is reported to be as high as 80 mg… Results showed that clinical signs may be seen in some animals at doses lower than previously reported. The clinician should be aware that clinical signs may develop even at dosages previously thought to be of little risk (e.g., 0.2 to 2.5 mg/kg in breeds historically considered to have normal p-glycoprotein function).
