REMEDY FOR CHEWING
Young puppies like to "mouth" everything. I use Bitter Apple spray on all my furniture corners weekly until puppy can be 100% trusted. You don’t want to take a chance on your favorite chair. Also, when pup is putting his mouth on something you don’t want him to, say “no” with low voice (never use high pitch, excited voice to train or reprimand the dog – he/she will not respond with respect, you need to establish an authority and a low, calm voice is the key to it) and then give him a toy that he is allowed to chew on and praise him for doing so.
TRAINING PUPPY TO GO OUTSIDE AND MORE :
When you bring your puppy home, it was exposed to and accustomed to clean environment; your pup would have learned to eliminate in the special indoor pan lined with newspapers and clean indoor area where it sleeps, eats and plays with toys. You should immediately establish a specific “going outside” area for your puppy in your yard. That area should be separated from the rest of your yard, maybe somewhere in the corner further away from the house (dogs naturally like to go to the far end of the yard). Establish one word commend for going outside, for example "go". Remember to use firm low tone when you give that command. To dogs low stern voice means the tone of authority; in contrast, high pitch voice stipulates excitement and play. Praise him once he has finished eliminating in the appropriate area with words, patting, and a treat. Food treats and Clicker work wonders. Clicker is used to immediately without any delay acknowledge that "the good deed" was done, then follow with the treat. Keep in mind that dog's attention span is very short, only about 5-6 seconds, by the time you get to the dog, accross your yard, he may not know why he's being rewarded; hence, the Clicker. Clicker is very inexpensive device ($4-5) and can be purchased thru online stores like KV Vet Supply etc... We use it for training of our dogs and it works well for us. You will be amazed how this simple device will speed up the housebreaking process.
As a training guide for dogs and puppies I recommend book "Dog Whisperer". I love the gentle teaching approach and a positive reinforcement it stresses. It is easy to follow and understand.
If you have a new dog or a puppy, you can use the crate to limit his access to the house until he learns all the house rules—like what he can and can't chew and where he can and can't eliminate. If you properly train your dog to use the crate, he'll think of it as his safe place and will be happy to spend time there when needed. Your dog's crate should be just large enough for him to stand up and turn around in. If your dog is still growing, choose a crate size that will accommodate his adult size and use a divider. It's important to keep two things in mind while crate training: the crate should always be associated with something pleasant, and training should take place in a series of small steps. Don't go too fast. Put a soft blanket or towel in the crate. Encourage puppy to enter the crate, drop some small food treats nearby, then just inside the door, and finally, all the way inside the crate. Each time you feed him, place the dish a little further back in the crate. Once your dog is standing comfortably in the crate to eat his meal, you can close the door while he's eating. After your dog is eating his regular meals in the crate with no sign of fear or anxiety, you can confine him there for short periods of time while you're at home. Call him over to the crate and give him a treat. Give him a command to enter, such as "crate" Repeat this process several times a day. With each repetition, gradually increase the length of time you leave him in the crate and the length of time you're out of his sight. Once your dog will stay quietly in the crate for about 30 minutes with you out of sight the majority of the time, you can begin leaving him crated when you're gone for short time periods and/or letting him sleep there at night. You might also want to leave him with a few safe toys in the crate. A crate is not a magical solution. If not used correctly, a dog can feel trapped and frustrated in it. Remember that puppies under six months of age shouldn't stay in a crate for more than few hours at a time. Also, puppy can hold (pee and such) for as many hours as it is old, for example: 3 months old puppy will hold comfortably for 3 hours, 4 months old for 4 hours etc... Just because pup can hold sometimes longer, don’t expect him to do it all the time. It is more of a mental maturity then a physical ability. Crate is a great tool that may prevent your dog from being destructive or from hurting itself while alone.
