Owners are now taught to train their pets to participate in their own veterinary care. Using positive reinforcement, a cat can learn to accept a blood draw; a dog can learn to present its paw for a nail trim. This reduces the need for chemical or physical restraint, which carries its own risks (e.g., hyperthermia from stress or injury from struggling).
: Behavior is a primary metric for assessing animal welfare. Scientists use "naturalness" (freedom to express natural behaviors) and emotional states (observing signs of happiness vs. anxiety) to determine an animal's well-being.
