How to Housebreak a Puppy
How to housebreak a puppy is a priority with the arrival of a new puppy. This is the number one thing to teach your new pet. You'll find a lot of web sites on how to housebreak a puppy on the internet. One I like is sit-stay-fetch and I rely on this course for all my pet training.
General rules on how to housebreak a puppy is a commitment from all my family members. Just remember that dog training is not a race. The key to a well trained pet is to establish good habits early. In your puppies mind there is no right or wrong place to go potty. If they feel like going they just go. It is our job to train them where it is acceptable to go potty and where not to go potty. No matter how well you are house training your pet there is bound to be the odd slip up. Don't get upset about it this will happen. Just make sure you clean up the area thoroughly.
You need to understand that your dog is a very young animal. Young puppies can only hold on for so long before they need to go potty. They don't have much control early on in their life. You will need to take your dog outside every couple hours. When you take your dog outside to go potty, start using a word that you like to attach to the act of going potty. This is the first obedience training command you will teach your young puppy.
When your dog is going potty continue to repeat that word. Then when your dog has finished going potty praise him or her for a great job. Make it clear that you are very happy with him or her. Continue with this housebreaking schedule until your dog goes to the door on his or her own. Remember that you are trying to prevent any mistakes and at the same time build good habits in your young dog.
