To isiNYC: (sorry it is long!)
Well, we got him when he was 6 weeks old and we immediately started with the crate. I read that it was good to have it next to your bed and put your fingers in there at first to let the dog know you are there and he is not abandoned, and we did try that the first night. Luckily, it was our spring break (we both teach) and it was okay that we got zero sleep b/c we slept a total of about 30 mins. Seriously. He cried all night long. I just knew he would eventually wear himself out and sleep, but never. We decided that wouldn't work. So, we moved him out of our bedroom (so we couldn't hear the crying) and set an alarm for every couple of hours to take him out. That way we knew the crying was just to get out and not b/c he had to potty. Then we started waiting until he became very asleep and groggy at night before we would carry him off to the crate. That way he would go in willingly b/c he was so tired he would just fall back asleep. We still do that for the most part. We play play play until he just wears out and then we head to bed. When we are letting him out for a quick potty break, we draw him into the crate with a treat. He will walk right in and not even cry then or at night now. He does not love his crate, I must say that, but he is definitely doing great at it, he doesn't hate it at all. He has not ever had an accident in it either. He seems to know that is his den and he won't mess it up. We still set the alarm and get up at 2 to let him out every night. We also made sure we NEVER got him out when he was crying. B/C then he thinks crying will get him out. My best advice is, this is a tough love thing. Just let him cry some, it will not hurt him. Start small. Give tons of praise. He will eventually learn that this is a safe, comfy place for him. I'm sure you do, but we have soft blankets, and safe toys in there for him. Place the crate somewhere where you can't hear the crying at first until he adjusts just so you can handle it. Then eventually you can move it back to your bedroom if that is where you want it. Anyway, sorry so long, hope it helps! He will still love you even if he has to stay in there and be unhappy for a while....he will learn and adjust and be happy!! GOOD LUCK!
