Puppies start gaining control of their bathroom functions at around several weeks of age. About this time “bathroom visits” will become more regular. However, due to a small bladder puppies will still need to go to the bathroom about 6 times per day. By the time the puppy has reached 8 weeks of age they will have much greater control of when they go. This is also the age that a young puppy will be developing preferences on where they will go. Now is when you should start house training.
The first step in housebreaking a puppy is to take it outside frequently to use the bathroom. You should take the puppy outside right away after it wakes up, after play time, approximately 15 – 45 minutes after it finishes eating a meal, and other times totaling at least 6 – 8 times per day. Once outside, and in a suitable location, allow the puppy to sniff, pace, and explore slightly for the exact spot the puppy likes. The location you choose should have several considerations before taking your puppy there. Young puppies do not have strong immune systems, so avoid places where other dogs and puppies go to the bathroom. You should choose a puppy potty location that you can take him or her to consistently. This will make it easier for the puppy to remember why he is there, mostly from the smell of his previous visits. Many puppies may need 15 to 20 minutes of sniffing and pacing before they are comfortable enough to go to the bathroom. The sniffing and pacing is very important, however, this should not become a playtime or play place. Because of this, keep in mind the “play areas” when choosing a location.
While the puppy is using the toilet, you should repeat a key phrase such as “go potty”, “make poop”, or “do your business”. Your puppy will learn to associate this phrase with an appropriate time and location for going to the bathroom. To avoid confusing the puppy, choose a short, simple phrase not commonly used in conversation. Eventually your puppy can even learn to use the toilet on command!
Playfully chewing, biting, and mouthing of you and your clothing is to be expected from puppies, It is not only natural, but also instinctual for puppies to chew and nip.
Here is how to help your puppy learn good bite inhibition. To start, you will need to decide how much is acceptable and when it becomes too much. Some people are comfortable with a dog touching their hands with teeth if no pressure is placed on it. Other people prefer no tooth contact at all (this is important with large, strong jawed breeds). Next, as soon as your puppy has “gone too far” let out a loud yelp and turn your entire body away. Walk away a few steps, keeping your face and eyes away from the puppy. Do not speak to him or touch him. You may feel silly doing this, however, the purpose is to socially isolate him for about 15-30 seconds. This is long enough for him to notice, but not long enough for him to forget what he did right before you yelped. If other people will be around, you need to make sure they do the same as you. If they start playing with or giving attention to your puppy during this time it will be for nothing.
hope this helps
