[header] How to brush your dog without tickling it [title] Accept your dog's natural scratch reflex. [step] Any time you touch a dog's sensitive areas, it creates a ticklish/itching sensation for the dog. This causes a reflexive response in which a dog will kick one or both of its hind legs. <sep> (A) The reaction does not signal to the dog that it's being scratched. The dog is constantly running away from you and this acts as a sign to ignore your brush. (B) Because dogs stand as they move, their ability to control their body's movement involves its memory of the gesture. In time, the behavior triggers an annoyed yelp from the dog, and will trigger a retaliatory yelp. (C) To avoid this reaction, expose the dog to the irritation but not let it strike your hand. [substeps] You cannot touch a dog's sensitive spots with a magic wand. (D) Your dog cannot control this reaction, much like how you cannot control the way your leg kicks when a doctor strikes your knee. [substeps] You cannot train or punish this reaction out of your dog; you simply have to accept it and work around it when brushing.
