Here is what to do for " touching exercise".
Dogs like to be touched certain parts and there is some area they don't like to be handled and touched. Most dogs don't like the tip of their legs to be held, their bum being touched, or their muzzle and mouth area being held. Some dogs also don't like their ears and tail being touched.
You can do the following exercise whenever your dog is by your side. You can do this exercise even while watching TV. You don't need special training time.

3 Easy Steps For Touching Exercise

1) Pat and stroke any part of your dog where he/she likes it or is comfortable with it.

2) Hold the areas where your dog doesn't like to be touched, like paws, muzzle, bum, and tail
Start slowly and proceed a bit at a time. First, touch this area a just moment. If your dog lets you touch these parts, praise your dog thoroughly.

3) Stroke immediately the areas that please your dog as a reward ( neck, breast, the base of the tail, back of ears, and so on )
Repeat this procedure for a few seconds and gradually lengthen the time to touch these areas.

The dog has to get used to being touched by you.
If you can do this exercise easily, brushing and combing your dog will not be a difficult task.

There are many benefits to being able to touch any part of your dog's body. You cannot brush but also occasionally clean mess around bum area, wash paws and you can clean around the mouth and eye stains.

All the same time, your dog will be much less stressed every time he is being groomed by you or a professional, or even visiting the vet. It is also useful in an emergency.

Your dog will start to like to be touched by other people as well. It means that your dog will become more confident and friendlier when meeting other people.

Do it before taking a walk, or before mealtime. Make it so that your dog expects something pleasant after grooming.
It's a good rule for your dog to be groomed in the same place at the same time every day.

Do everything to condition your dog to accept grooming and make it a pleasant time. As a result, you will get more trust and respect from your dog.

This exercise is as important as teaching " come, sit and stay commands" of the obedience training.
