This is my all day collar. When it is locked around my neck it takes a couple of minutes until it is nice and warm and I hardly feel it anymore. My master has got the key - I cannot open it. It is like a wedding band to me, because I know who my owner is. And it also shows that I am owned. Do you like it ?
It is the most comfortable one, because it is not so heavy like the other ones I have... What do you think this one weighs ?
