Hello Erica! Is your "avatar" a photo of your new baby (maybe "Penny"?) - what an absolutely darling puppy!
We did not crate train our first dog (a Corgi mix) - he was just "one of the kids" - or maybe they were his littermates! Our four children were ages 3 to 10 so, as you might imagine, there was not a lot of structure or order in our household at that time! Wimsey was my first dog EVER so it is truly amazing that he turned out to be the wonderful, loyal family member that he was (for 15 years!!) He slept with the children at night, he roamed the house during the day - I was fortunate to be an at-home-mom, so my circumstances allowed him that freedom.
Chloe, our charming little Pem, is our "empty nest" dog, and even before we had picked her out, we knew she would be crate trained. It has turned out to be a very appropriate decision - for both us and Chloe. As others have stated, the crate (and it is a large wire one...) is her "nest", her safe place. She has slept in it every night since we brought her home. She naps there when we leave the house . We feel confident that she is secure and I believe she feels secure there, also. One very big plus - when we travel, we fold the nest down flat, put it in the Jeep and go with her. When we arrive, we pop up the crate and Chloe feels right at home! She has never skipped a beat during overnighters! This summer we are going to be very daring and try taking her camping (it may prove to be cozy in the tent!) - I will let you know how that goes!
To conclude, crate training proved very worthwhile for us. We have never used the crate for punishment or as a "cage" so I believe Chloe does not associate it with anything negative. In fact, during busy times around here, I think she is grateful to have her own place to which she can reteat!
Good luck with your puppy! Hoping all our "input" will be helpful to you!
