#10 Take your puppy outside immediately after eating and walk until he does all the necessary work.
Once the dog does what you expect, praise and treat him. After a while, the puppy will learn what the main purpose of the walk is.
#11 Next comes collar and leash training.
The collar is put on for a short time, then removed. It is better to distract the puppy by playing. Later, the wearing time of the collar increases. When your baby is used to the collar, attach the leash. If your dog tries to chew on the string, distract him.
