My sister trained her dog to stand with her legs successfully

Looking at the dogs standing with 2 hind legs, you really want your dog to have that technique, but please pay attention to the following "just train your dog when the puppy is over 6 months of age because otherwise it will affect the hip bones of dogs ”.
The first step: from the dog posture facing you. You stand in front of it so that the distance is enough for the dog to stand up and not get caught up in the friend, and you remember not standing too far because it will lie down.

Second step: Use food to sniff for the dog to smell it but not to eat it. Hold the hand close to the smell of the dog to make it sniff. Slowly the hand is raised and slightly above the top of the dog's head so that it must raise its head. So the dog has to lift his legs off the ground. As soon as the puppy lifted the legs off the ground, you clicked Clicker and immediately rewarded the food. Repeat several times and gradually raise the food up until the dog can sit with both legs and back straight with the head.
Step 3: because this is the first time, the dog is not used yet, so when you lift 2 legs up, you will have to put it down, let the dog return to the sitting position.
Step 4: Repeat step 1. Each time to get your puppy to raise his leg a little bit higher, then click Clicker to make the dog have to raise his foot as high as possible but still keep his balance. Click Clicker as soon as the dog holds the person in position to lift 2 feet off the ground for 1-2 seconds. Next take the food higher and move forward a short distance. Dogs sit with two legs but don't get food so they will jump forward to get food. At this time, you should hold food outside for your dog to see and move food slowly forward.
Step 5: When the dog has been practicing for a while, he can sit comfortably with his butt and raise his legs, then start to join the SEXY command just before clicking clicker and reward him
- You should note a little training of these skills, we need some patience and practice slowly and gently so that our dog is not bored and confused
Good luck
