We 've had our 6 month old rescue dog for 4 months now and bought a large crate when we got her. It's been sitting in the corner of the living room since she arrived and occasionally she would wander in, sit for a minute, then wander out, so no fear of it but no great affection either. We didn't crate her from the beginning as she was generally a nervous dog and came from a cage at the dog shelter....
However, our house is very open plan ( no doors downstairs) and our gorgeous spirited pup has eaten shoes, remote controls and most recently fairy lights. She has even chewed on the hand of my prized antique house Buddha (poor Buddha now has mustard on his fingers as a deterrent, thankfully a forgiving religion...)
Our trainer advised us to pursue crate training to stop her chewing (and sleeping on the sofa) so we've been crating her for 20 minutes, 30 minutes, an hour at a time with treats over the last 3 to 4 days. The last 2 nights, she's sleep in the crate and today I told her to go to her house and she just went in, happy enough. I do feel the reticence about the crate was 99% on my part now. If anyone is undecided about crate training, it's really worth pursuing and generally not difficult.
Our dog trainer says that he knows dogs who go straight to their crates when the doorbell rings .... That's worth training for!
