Multidrug Sensitivity in Dogs


Some dog breeds are more sensitive to certain drugs than other breeds. Collies and related breeds, for instance, can have adverse reactions to drugs such as ivermectin and loperamide (Imodium). At Washington State University's College of Veterinary Medicine you can get your dog tested for drug sensitivity and keep up with the latest research.

Drug sensitivities result from a mutation in the multi-drug resistance gene (MDR1). This gene encodes a protein, P-glycoprotein that is responsible for pumping many drugs and other toxins out of the brain. Dogs with the mutant gene cannot pump some drugs out of the brain as a normal dog would, which may result in abnormal neurologic signs. The result may be an illness requiring an extended hospital stay - or even death.

Test Your Dog

IMPORTANT NOTICE

The discovery of the mutation of the multi-drug resistant gene (mdr1), establishment of testing procedures, and development of all reagents was made by Washington State University. It is also a patent protected diagnostic test offered exclusively by Washington state university that has not been licensed to any other entity in the united states. It is licensed in Australia and Europe. Any unlicensed use or marketing of the patented test is a violation of federal statute under 35 u.s.c. 271. Unless testing is conducted by Washington State University's veterinary clinical pharmacology laboratory, Washington state university cannot control quality and accuracy and consumers may risk receiving inaccurate results.
