crating question

Two puppies at one time is really tough.  You will have to work hard to ensure that they bond with you and your wife and not with each other.  You want to make sure that they each want to be with you and your wife more than with their sibling.
 
I'd definitely crate them separately (and probably in separate rooms) and were it me I wouldn't even keep them together during the day except for brief playtimes.  Separate training session, separate car rides, separate just about everything.  Not forever, but for many months. 
 
I hope this doesn't come off as harsh, but my dogs all do either agility or work sheep so my "working" relationship with them is very important.  I want to be their focus - not their sibling.  Even if all you ever want from your dog is to have him and her be good pets I'd still start with separate crates right from the beginning.
 
Have fun with them - double the fun but double the work [sm=happy.gif]

Wow!!! I can't even imagine taking on 2 puppies at once!! I have hard enough time keeping up with one puppy and a dog stuck in the teenage state of mind!

I would not crate them together. Their crates become their place to get away and enjoy some quiet time and if they are sharing the crate, they don't get that opportunity. My older dog does not have to be crated when I go to work anymore and hardly uses his except for his place of refuge but when I brought my puppy home I got another crate for her. Sometimes I give the older dog a bone or something and he likes to take it to his crate so he can enjoy it without the puppy trying to take it.
 
They will play together in the crates, but as far as ever shutting the door and putting them in together, I wouldn't ever do it.

Bonding is good for them, but you do want them to have a stronger bond with you than with each other, as was already mentioned.

Trish?  Try SEVEN at once!! 

I had my girls in the same crate for about 6 weeks.  My reasoning was this.  If I had seperated them I would have had to buy 4 new crates instead of 2.  The one I had would have been too big for just one of them so i would have had to get smaller ones, then as they grew they would have needed bigger ones.  Now they are a bit bigger and can get irratated with one another so they have started sleeping in seperate crates at night.  They have just taken over Crusher's crate and he has been sleeping upstairs with us.  If we are leaving for a long period of time during the day they still get crated together so that Crusher gets his crate back.

They get  one on one time with us though during the day.  They each get a seperate walk, and a seperate training session or 2 or 3.  I dont feel the need to seperate them more than that though since they are going to be sled dogs and need to spend time with their team.
