My biches nose is always running, i have phoned the vet a while ago and he said nothing to worry about, but this has been going on for over  six months. She is a very calm laid back bitch, not at all nervous or exitable. She is always licking the fluid from her nose as it is really runny. Do you know anything about this as i have never seen anything like this before.

Is the fluid clear?  If so, I wouldn't worry......

Yes it is clear.
