Hen hates e-collars, but she'd eviscerate herself if left to her own devices. Whenever I was home, I'd take it off and leash her so I could keep an eye on her. I hate those collars too, they're miserable for the dog. I kept having to wipe them clean because even though she's not a drooler (I pity people with drooly dogs and e-collars) the thing was like a funnel to catch every sneeze, every drop of moisture, every food-staring-drool, and all her loose fur. It was filthy every single day until I wiped it off.
That said, better safe than sorry, and it's only 10 days. I'd leave it on when I wasn't home.
edited to say: Don't forget to check in her ears. In Hen's case, the humidity caused by her breathing inside a confined space did a job in her poor ears, which got very dirty very fast.
