Hi i'm a little concerened with my bithches teats.

The old girl likes her underbelly rubbed (which dogs don't) and recently one of her teats have been excreting a little blood along with some milk.

The milk is nothing new she normally leaks a little around once or twice a year but the blood has me worried.

I thought I'd check on here before I take her to the vet, does anyone have any experience of this?

Hi Cassiedog. I would have her checked by the vet as soon as can be arranged, with holidays and all. Could be an infection, but also something more serious.
Either way she would be needing treatment.
All the best,
Karen
