their adult female dobes neck. I need the measurement where you would put the collar. I have decided to make my own. I went today and got the leather, conchos, etc. I figure if it works out and looks good I will start selling them. I don't like alot of the collars at the petstore, they all look the same. I guess Im a little strange that way. The leather is very soft but durable and you can waterproof it! Anyways I would be really grateful if someone could do this for me.
