Nonetheless, it occurs very frequently in certain dog breeds, such as Collie, Bobtail, German-, English- and Australian Shepherd. According to literature data the occurrence of MDR-1 mutation can reach up to 30% in certain dog populations. The susceptible purebred individuals and their mixtures show serious poisoning symptoms (ataxia, languor, seizures) after administration of safe drugs used in veterinary medicine. These drugs that are frequently used in veterinary practice e.g. ivermectin, loperamide, doxorubicin, cyclosporine, digoxin, acepromazine, butorphanol and many other compounds. The affected dogs often die in spite of the symptomatic treatment.<\/p> <p>During our investigations blood samples are collected from the largest possible population of dog breeds concerned.
