Well the first couple of nights she had no crate. so i introduced her to that and she took to it no worries then when bed time came i took the crate into mour bedroom, i put a warm wheat bag in under her blanket, lured her in with a treat and shu the door. No whining at all. after she went to the toilet and i put her back in she whined for 30 seconds then fell asleep. i had maggie my older dog sleep next to her which they both seemed to like.
