Keep in mind the pup may be afraid of the doggy door at first. She might actually learn to pee on her bed if she is afraid to go out into the yard through that door. So make sure she understand how to use the door and realize it might take her some time to get used to it.

I am about to get a female german shepherd puppy, i have not toilet trained a dog or pup ever as all my previous dogs have been out in the yard.
so yes i have been reading alot trying to find the best method because i would like to have a dog living in the house with us.
i to thought about puppy pads, crate training,.
now my pup will only be at home on its own 3 days a week for up to 5 hours max….i do understand and agree that crate training is not harmful when done the right way, but for me i dont think i could leave a pup or dog in a tiny crate, thats just me. because some one will be at home most of the time to watch for the signs and be able to take her outside it is only the 3 days a week im thinking of. so here is my question….the goal in the end is to have my pup use a doggy door to let her self out (sliding door type) i had an idea along the same lines of crate training, by getting a small play pen and putting it around the doggy door, i have read that dogs do not like to pee or poop where they sleep, so for the first while i will make that the pups bed just big enough for a pillow, or something to sleep on. so what im aksing is will this work? i figure i will be killing to birds with the one stone, im not locking her into a small crate for hours when im not home by alowing her to come and go through the door, and also teaching her to go to the toilet outside? eventually moving the pups bed else where, or maybe starting off by making the play pen alitter bigger step by step till she gets the idea.
to me this sounds like a good idea that will work, but i could be wrong…any comment please:)

Let me know if you have any questions after reading that. Basically take him to the same spot outside every time and give him a treat when he goes. If he doesn’t go, then put him back in his crate for 20 minutes and then take him outside again. Repeat as necessary. Once he’s gone, then let him have a bit of freedom. But then keep him in your sight at all times, like on a leash “tethered” to you. Ditch the pads completely. They just confuse a dog. I know way too many little dogs that pee on rugs, pillows, towels, anything on the ground that resembles a “pad.” If you are consistent and patient, he’ll catch on with time.

I’m sure she has a lot of pent-up energy. Puppies nip and bite anyway when they are teething, but they also do this as a form of play and to get attention. She needs a way to get rid of all that energy.

I really think you should be taking her for walks as soon as possible. It’s not fair to be upset with her when she has all that energy and nothing to do with it. If you can’t take her for walks outside, then play tug of war with her (using her toys!) in the house or leash her up and practice some heeling around your house. Play games with her by hiding treats under cups or buckets. Get her some interactive toys like Kongs. You can put treats in these and she will work to get them out.

When she bites or nips at your hands or clothes, I suggest re-directing her with her own toys. This is when playing tug is appropriate. It’s a great game to help a dog release energy. Don’t keep her toys out all the time or she will lose interest in them. Get them out for 10 minutes here and there and rotate which toys are out. If she is nipping at your clothes, then offer her something appropriate to chew on such as a rope toy. When she is biting your hands or clothes, you can try giving her a very firm “NO!” But if she seems to enjoy the attention (even bad attention), I recommend that you get up and walk out of the room without saying anything. Ultimately, she is biting as a way to get your attention and to interact with you. If you leave the room whenever she bites, she will learn that if she bites, she gets nothing. Return after about 30 seconds. If she jumps and bites, turn and walk away again. Give her attention whenever she is calm, like when all four feet are on the ground or when she is playing with something appropriate such as her own toys.

So yes, a lack of exercise is a big part of the problem. She should grow out of the habit if you work on re-directing her and not giving her any attention for biting. Most pups lose their puppy teeth at around four months. So she is probably in that teething stage and getting ready to lose those puppy teeth and get her adult teeth.
