Keeping an injured pet quiet is a lot of work. But always doable if the desire is there.
I just wanted to address this.
A year or so ago I got my kelpie bitch desexed. She has been a farm dog all her life, she lives in a pen and is let out to run and comes for rides with me on my horse. The only time she is ever on a lead is a few times a year when I take her into town.
I took a week off work as I knew she would not stay still in her pen and in addition the pens aren't exactly sanitary.
I was with her 24/7 - She slept on my bed so I could keep her still. I walked her outside to go pee. I kept her on my lap durig the day so she couldn't run around.
Despite my best efforts to keep her still and quiet, she had moved around too much and developed a hematoama (sp?).
It's not always possible to keep a working breed dog still enough. She would have struggled mroe tied up than not as she isn't used to it.
