Generally, dogs that normally drink a lot of water will have larger urine output and more frequent urination. It is usually normal for dogs to urinate 2-3 times a day. If you find that your dog has been urinating recently, or has wet urine, or there is blood in the urine, this often means that the dog has a urinary tract infection or urethral stones.
And the younger the dog, the more times it urinates every day. Normal urine should be light yellow in color with a faint urine odor.
