I wouldn't worry to much if she gets fidgety and acts really goofy when you put it on her. Harley took a LONG while to get used to his collar.. He always found a way to get it in his mouth!? Just make sure you keep an eye on her while she has it on. I don't recommend leaving it on her while you're not around until you're 100% sure she won't try and get it off. I just put Harleys on when we go out for walks and take it off when we're in the house. Just to be safe!
