Veterinarians serve on the front lines working to prevent animal suffering and abuse. For centuries, their compassion and expertise have improved the quality of life and death for animals in their care. However, modern interest in animal rights has led more and more people to ask questions about the ethical considerations that lie behind common veterinary practices. This Common Threads volume, drawn from articles originally published in the Journal of Animal Ethics (JAE), offers veterinarians and other interested readers a primer on key issues in the field. Essays in the first section discuss aspects of veterinary oaths, how advances in animal cognition science factor into current ethical debates, and the rise of complementary and alternative veterinary medicine and its relationship to traditional veterinary medicine. The second section continues with an essay that addresses why veterinarians have an obligation to educate animal caregivers to look past cuteness in order to treat all animals with dignity. The collection closes with three short sections focusing on animals in farming, trade, and research areas where veterinarians encounter conflicts between their job and their duty to advocate and care for animals.
