Look I am already Trained on the Lead

It is never to early to start training your puppy, the earlier you get him use to a collar and lead the better he will accept them.

At first he will find it strange and try and scatch it off, just be paitent as he will soon get use to it and accept it.

The same goes for attaching a leash, just have it really loose to start with and go in the direction of the puupy until he gets use to it. Then get his attention either usung your voice or a treat so he starts to follow you.

Keep working with him for just a few minutes at a time several times a day and then build the length of time up. This will really help when he is ready to go out walking. It is also a good time to start introducing the word "heal" or similar command you wish to use.
