Timber's collar is on all the time. She's never had any problems with it, but she does like it better off -- I think it starts to irritate her nexk after a while. I think that it's better for her to have her collar on 24/7 because my aunt keeps her outside most of the time (Timber doesn't like being inside -- I think she gets clostrophobic or something).

When I get my catahoula, he'll only have his collar on when we go out. I'd be worried that he would somehow get away. ID on a collar is so simple that anyone could pick him up and just bring him to me. Of course he will be chipped and tattooed as well, incase he slips out of his collar or he gets out of my house.
