Dog is acting normal but urinating a bit impatiently. Can it be UTI?

My dog has been drinking more water that usual can this be because of the weather change (it got a lot warmer here) and she doesn't urinate in the apartment but whenever I bring her out of the apartment to take her for a walk she urinates in the hall and the last time shes done that was a few years ago its like she cant hold it in. I take her out 4- 3 times a day so she can do her business. But shes acting normal and is up and about. She is a 11 year old Lhasa Apso. What is wrong with her I am going to take her to a vet but I am not sure if this is just normal due to weather change.
