Do you think my dog has a UTI?

So my dog had clear discharge from her urinary area today, like a short string of saliva. She has also been licking that area more lately.

The vet can’t see her until Tuesday. Do you think it’s a possible UTI or what could it be?

She’s an old lady lab/chow mix, fixed, around 10 years old. She does have some lipoma’s, but I was told when I got her cancer was ruled out and she had been tested.

She doesn’t act stressed or in any way uncomfortable, except the licking and a little leakage. My male smelled the leakage, snorted and walked away, which is what triggered me to pay more attention.

We keep fresh water out and a grain-free, holistic dog food, which is no different than usual.
