Don't worry about it. Just tough the first day out and the dog acclimatizes to the e-collar afterwards. Cadence hated it when I first put it on him (after his neuter), but after a couple of days he LOVED it and would spend the entire day licking the insides of the plastic. I know, really disgusting. I ended up having to wash it every day because it smelled like drool. I took it off during walks and such though.
