It instills trust in you and builds a stronger bond. Your dog learns to trust that you will keep them safe, and in turn this builds a stronger bond. Furthermore, touching your dog causes the release of the “love” hormone, oxytocin, in your dog's body that helps calm your dog.
How do you handle a dog?
Stay calm and relaxed. Be firm but not aggressive. Remember that even very good dogs may bite/resist if something is painful. Use a muzzle for painful procedures (unless the patient has head or neck trauma), muzzles should never be left on for more than 15 minutes without giving the dog a break.
Why do dogs need human touch?
“Dogs are social animals, and they produce oxytocin [also called the “love hormone”] when touched, just like we do,” says Amy Cook, a dog trainer and behavior consultant.
What happens if you don't give your dog enough attention?
This can lead to biting behavior and enforce negative habits, which become even more problematic as they get older. You should also make sure not to show your affection through food; this can predispose dogs to begging behaviors and medical problems related to obesity.
