Dog drooling more than normal

[millimoo]

I have a 3yr old Chocolate Labrador Bitch.
This evening i've noticed she's drooling more than normal - its not streaming out, just a drip, drip, drip. I thought it was because I was having my tea, but now realise (after vet has closed) that's she's drooling anyway, and is leaving wet patches where she lies.
I've checked her mouth for foreign bodies, all he teeth look fine, and I can't see any inflamed areas in her mouth.
She eating, weeing and pooing normally too, and is her usual self and bright / happy etc.

I'll bob her into the vets tomorrow if she's still doing it, but in the meantime any suggestions.

Edited to add - she's had the odd shake of her head as if her ear is a little iritated, although both look clean and she's happy for me to touch them etc, and has not been scratching them etc. She was treated with Advocate a week ago too.

Abe was like this when he had an inner ear infection. I too couldn't see anything in his ears they looked healthy and he would let me touch then ect but the vet got in there with a scope and found an inner ear infection.

I would pop to the vet in the morning.

thanks Katielou, I do wonder if it might be her ear.
Although she's not lopsided, and her mouth is absolutely clean - she's been sat here with her mouth wide open whilst I took another thorough look bless her.
I also can't see or feel any swelling.
Definitely the vets in the morning.
