Tough Love
Tough Love is setting your dogs expectations and holding him to that no matter how cute he is or how easy it is to let him get away with it.
You need to look at your dog and think about what kind of behavior you want from him for the remainder of his life with you. This is how you get the kind of dog that you want. Don’t wait for a problem to occur before you think about the appropriate behavior that you want.
Let’s look at some examples:
Don’t take the collar off your puppy just because he doesn’t like it. He is going to have to wear one, so he must get used to it. Have tough love.
Not using a leash because he didn’t seem to like it the first time. He is going to have to be on a leash at some point in his life. Have tough love.
Picking him up and not letting him interact with other dogs because of his nervousness. You do this and he will never learn how to be a dog, he will have low confidence and you are likely to have dog aggression issues in the future. Get past your nervousness and have tough love.
