I have an almost 11 week old female gsd puppy. We've been working on potty training for the past couple of weeks and although she has made improvements we still are having accidents and issues. Up until this point I have been taking her out "letting her follow me to door and we go outside to yard together without leash" usually in morning, after meals, after sleeping, and after play time. I guess the main problem is that she isn't alerting me as to when she needs to go out and does not go to the door on her own. Should I be leashing her and taking her out everytime?
I would. Although I know it seems
like a long time, 3 weeks really isn't that long. At 11 weeks old, she's still very much a baby, and as such, has little bowel or bladder control. Like a human baby still in diapers, she probably doesn't recognize that she needs to go until right when she does, so there's little advance warning. And she's also still learning that there's only one appropriate place to eliminate - outdoors.
How will she learn to let me know when she needs to go out?
First, she needs to know that she HAS to go outside to do her business. Until then, you can't expect her to alert you to take her out.
Up until this point the breeder had the puppies in the kennel were they had become accustomed to using the bathroom in the kennel.
I keep her in the kennel at night and when I am away from home but she still continues to urinate in the kennel
This could certainly be part of the problem, and can set back your housebreaking efforts a bit. But puppies will naturally vary in how long it takes them to learn. The more diligent you can be about not allowing accidents in the house and the more you can succeed in getting her outside to potty (and to reinforce that with happy praise and a little treat), the faster it will go.
We got Dena at 9 weeks old, and her last accident in the house was about a month later. It would have been earlier than that, except that we made a couple of mistakes, like forgetting to make sure she pottied before letting her in the house when we got home. We have a secure outdoor run where our dogs go when we leave, and she was so excited to see us that she came in and then peed on the floor. Oops! Totally our fault.
If I remember correctly, Keefer took about twice as long. He was a very thirsty puppy, and would drink a lot of water and pee frequently. We got Halo at 10 weeks old, but she was a little thing. It took around 3 months for her to figure it out. Be patient, be diligent, and supervise her very closely. Keeping a lightweight leash on her in the house, and even tethering her to you are good ways to make sure she can't wander out of sight for a moment to squat and pee.
