Start the proofing process, which means your dog will be proving he knows behaviors even in different conditions or environments. Professor Donaldson demonstrates how taking the same training regimen on the road can have different results and what to do to get over obstacles such as competing motivation, distractions, or problems with generalization. x
Various kinds of service dogs and assistance dogs, including guide dogs, hearing dogs, mobility assistance dogs, and psychiatric service dogs provide assistance to individuals with disabilities.[156][157] Some dogs owned by epileptics have been shown to alert their handler when the handler shows signs of an impending seizure, sometimes well in advance of onset, allowing the guardian to seek safety, medication, or medical care.[158]
The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety.[192] Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans.[193] One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not.[194] In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.[195]
The practice of using dogs and other animals as a part of therapy dates back to the late 18th century, when animals were introduced into mental institutions to help socialize patients with mental disorders.[196] Animal-assisted intervention research has shown that animal-assisted therapy with a dog can increase social behaviors, such as smiling and laughing, among people with Alzheimer's disease.[197] One study demonstrated that children with ADHD and conduct disorders who participated in an education program with dogs and other animals showed increased attendance, increased knowledge and skill objectives, and decreased antisocial and violent behavior compared with those who were not in an animal-assisted program.[198]
Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.[16] Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal.[16] Dogs are predators and scavengers, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing.
