Never leave a puppy in his crate all day; he needs several bathroom breaks, as well as play and feeding times. Even though he won’t want to soil his sleeping area, if he is in there for extremely long stretches, he just might. (He can’t help it!) And if he does, it is because his owner has neglected his responsibility, not because the dog has misbehaved.
Imagine your puppy running out the front door. You call him, waving a treat. But he'd rather chase a squirrel into the road than come back to munch on a treat. In addition to the obvious danger of Puppy getting hit by a car, he learns that he doesn't have to listen to you. He learns that he's in charge of what he decides to do and what he decides not to do.
Once your puppy can turn around to face you, begin adding movement and making the game more fun! Toss a treat on the ground and take a few quick steps away while calling your puppy’s name. They should run after you because chase is fun! When they catch you, give them a lot of praise, treats or play with a tug toy. Coming to you should be fun! Continue building on these games with longer distances and in other locations. When training outside (always in a safe, enclosed area), it may be helpful to keep your puppy on a long leash at first.
Once your dog can stay in a sit for several seconds, you can begin adding distance. Place him in a sit and say “stay,” take one step back, then step back to the pup, give a treat, and your release word. Continue building in steps, keeping it easy enough that your dog can stay successful. Practice both facing him and walking away with your back turned (which is more realistic).
Submissive urination is a normal way for your puppy to demonstrate submissive behavior. Even a dog that is otherwise housetrained may leave dribbles and puddles of urine at your feet when greeting you. Excitement urination with a puppy is usually caused by lack of bladder control. The puppy is not aware that he is urinating; he's just excited and any punishment will only confuse him.
