I see that you haven't yet viewed my answer. I wanted to make sure it got through to you, so I'm sending it a second time, below.
Also, how is Una doing today? Has she seen a vet? Please let me know, as I am concerned for her. Thanks!
I was hoping to get some additional information from you, but didn't want you to go too long without an answer.
If this clear fluid is coming out of Una's stomach, she may have a small cut or abscess there, that is draining and you weren't aware of it. If the color of the fluid is clear and does not have a foul smell, that's good, as a foul smell would indicated infection; however, this is not something that can be remedied at home, so Una will need to be seen in person by the vet, as soon as possible. In fact, if you have an ER vet nearby, bringing her there now, would be a good idea, so you can get a diagnosis and treatment for her.
If she is not spayed, and this fluid is coming out of her stomach and/or vulvar area, she could have a serious uterine infection called pyometra and needs immediate veterinary attention.
I hope you are able to have her seen by the vet as soon as possible, and all will be well with your Una!
