I'm having trouble establishing a routine with my new pup for when he needs to go to potty after eating. Is this normal?

My name is Kyle, and am a owner and lover of dobermans here in NY. I love your website, all the training information and have ordered your DVD on drive building. Ed, I have two wonderful dobermans who I raised since pups, and are exemplary in behavior and demeanor. Both my eldest two were crate trained from day one, their personalities built on positive praise, I am alpha and have complete and total control over my animals with voice command- NEVER by corporal punishment.

Ed, I feel like I might be slipping ;-) I have a new pup, he is 11 weeks old and is a product of pretty damn good Euro blood lines. I brought him home 11 days ago, he is completely crate trained(wow was he the hardest thus far but simple solution- he wants his crate covered) and a very clean dog (only one accident in the crate, and I am at fault for that, not the dog) Here is my issue with a potty training problem. I feed my dog based on the same idea you teach of 15 minutes, etc. He is relatively very structured to two meals a day, with his early meal being a light one by his choice. When done, he is taken outside alone and on a leash and as of late, he is not going to the bathroom as he did the first 8 or so days. So I figured, perhaps his constitution is a bit longer, so I stay with him and most times he'll need to defecate 15-30 minutes after a meal. The issue is that because he isn't going(and I don't believe he is bound up or has a medical problem) I have to continually bring him from outside, to the crate, then wait 45 minutes or so, take him out, then back to the crate, and so on. The reason is because- if I turn my back on him for as much as 5 minutes to have playtime, he will go in the house. Please know, I don't support turning even a minute of attention away from a pup, but it's the real world and sometimes so much as housecleaning or a phone call could have me turn away. Am I doing something wrong? Am I failing in structure? I dislike the potty attempt to crate, potty attempt to crate, as I do feel it's robbing him time that I know he wants to expel his puppy energies. I will not allow him the opportunity to decide when he will go to the bathroom and it will be on the floor.(He does NOT go to the bathroom in his crate).

As said before, I have raised two dobermans to exemplary standards - they are wonderful dogs who would be any person's desires to have in a home. I feel a bit lost with my little man though. He has much drive, is very confident, a bit stubborn but wins NO dominance over me. He is treated no differently than I treated my other two. Any suggestions?

Thanks Ed,
Kyle

P.S. Are males just more difficult in general? I really love the theories and methods of dog rearing as taught by you as well as others. I love investing my time, energy and efforts into my dogs. It just seems like boys are just a little more difficult than females in many aspects of puppy rearing- or am I way off base on this?
