If pup is peeing in the wrong place... you may be able to stop him. Move quickly towards him when he begins to pee and pick him up. Urgency is key here - you want to startle the pup just a little as you move towards them to pick them up, but you DO NOT want to scare the pup. You are redirecting your puppy to the right spot - not disciplining him. Immediately after picking him up, take him to the potty area and patiently wait. Most pups will finish there. Reward your pup with exuberance!
One of the easiest ways to prevent accidents is learning to recognize when your puppy needs to go out. Most puppies will sniff the ground when they’re getting ready to potty, but there are many other more signals that happen prior to sniffing. Puppies that pace, seem distracted and walk away from play are subtly signaling that they have to go out. If your puppy tries to sneak out of the room, take a potty break right away.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
