I brought my 9 week old Flat coated Retriever puppy home on Saturday and am having real problems settling her at night - I am trying to get her used to sleeping in her crate in the kitchen. For the last 4 nights, she has barked non-stop, and then is really tired all the next day. Is it normal for the crying/barking to go on this long? How long should I expect it? Everything I've read talks about 2 or 3 nights - but I think she is particularly sensitive.

I would like to bring her crate to my bedroom, but it is far too large to be moved and I could not possibly get it up the stairs. I am very reluctant to let her sleep in my room without it, as I prefer the dog to not go upstairs at all (to protect our hamsters and my kid's toys that are taking refuge there). Also, I do not want her to wee on my bedroom carpet - a crate can be cleaned.
Should I persevere or am I being cruel? I'm not sure how many nights of this distress is normal.
She gets lots of love, attention and play during the day.
Ideas anyone?
