Hi everyone, we brought our Berner puppy, Mila, home last week. She is nine weeks today, super adorable and lovely! We have not yet left her alone and we need to start. We have a crate, and have been feeding her in there and giving her special treats to have her go in the crate happily, and she will stay in there happily (while we're home and in sight, anyway). We tried lining the crate with a blanket - too hot and she didn't like it. We tried a bath mat - she peed on it. Another thin bath mat - also peed and then tried to chew it up. We had a trainer advise us to just leave the crate bottom uncovered (it is plastic). Mila seems ok with this, but just wondering what other people line the bottom of the crate with. We want her to be comfortable there when we start leaving her alone (it has to happen sometime!). Any other tips for having her love the crate would be welcome! Thanks!
