You're certainly trying to cover everything Phil which is good :wink:
I think it's a personal choice as to whether you keep a collar on at all times or not. Many owners who show their dogs do not keep the collar on at all times as it is rather noticable when removed.
I personally have always left Lotties on all the time. I fell into this habit after taking her to training classes where I was taught to always take hold of her collar after a recall before rewarding her with a treat. The reason being for this was so that the dog doesn't just associate it's collar being taken hold of when being put back on it's lead after a walk.
On the whole, Lottie is a good girl but I often find having the collar on around the house useful to be able to get hold of her quickly if needs be (she has a habit of hiding behind furniture if she has something she shouldn't :wink:
). Also having the collar on is useful to grab her when she's tearing in from the garden with filthy paws :roll: :wink:
On the other hand, some may say it's dangerous to have a collar on around the house incase it gets caught on something :?
The choice is yours :wink:
