No, this is all the same question.
If you read a veterinary text book, 75-120 would be considered normal for a dog.
60 is a little low but she has not eaten anything. I would feed her and check it again 2 hours after that. So you are checking her for diabetes mellitus. If she were diabetic, her blood sugar would be sky high. Usually over 300. But you can check her after eating just to make sure.
She most likely has a urinary tract infection. They are very common in female dogs. A simple urine test can check for that. If positive, she can take a course of antibiotics and that should be the end of it.
If she does not have a urinary tract infection, then blood work should be done. She is young so I doubt she has metabolic disease but it is possible. Her blood sugar is lower so diabetes is not an issue. The other likely causes of increased urination would be kidney disease or adrenal gland disease which is called "cushings." But neither would be common in a such a young dog.
I bet she has a urinary tract infection.
Did that help?
