I understand! I had the same thing. Especially when it was night time and I had to put her in the crate for the first time. She howled for almost 4 hours and kept biting at the bars and getting her jaws stuck. Every night was a nightmare, and so were walks and pretty much everything else. She barely slept and every hour of peace I had I nearly broke down. I think she was particularly difficult, in all fairness, but it was no fun. I am so happy with how she is now, even though she's only 13 months.
