Unlike adult dogs, frequent urination in puppies can be sometimes considered normal. In this case, your concern is totally unnecessary. However, you should do something if this behavior is a medical problem. In other words, as a dog owner you should first learn to tell the difference between them. Actually, you will be a better pet owner with a little help.
1. Urinating frequently is quite common in puppy younger than 12 weeks. Just like children wet the bed and their pants, pup is no exception since it can’t control its natural urges yet. This is because its bladder and urinary system are still not fully developed, which makes it extremely sensitive to the stimulation like excitement or tension. In general, your puppy will grow out of it after it is 5-month old;
2. Another possible cause is that you give your dog too much water. Actually, it has little self-control no matter eating and drinking. They won’t stop until too much water makes them nearly vomit. If you find it frequently urinating small amounts, you should record the water intake and then limit its supply of water if necessary;
3. Behavioral issues. Dogs tend to exhibit territorial behavior, especially when there is more than one in one house. If this is the reason causing frequent urination in your puppy, you need to separate them and keep them away from windows or glass dividers.
Apart from the mentioned normal causes, a number of diseases can cause urinary frequency to your puppies. It is best for you to consult your veterinarian if your dog is still frequently urinating small amount of urine. Thus, the veterinarian will find out what is behind it and give the proper medication or treatment.
1. Polyuria. This is a rental disorder accompanied by a need to urinate frequently. If your pup has polyuria, it tends to drink more water to replace lost fluids by discharging abnormally large quantities of urine;
2. Hematuria. This is often a symptom of urinary tract disease, in which red blood cells or blood can be found in the urine. In comparison, females have a higher risk of getting hematuria due to the shorter urethra;
3. Dysuria. This is a urinary tract disorder. Because of the obvious symptoms of discomfort and pain while urinating, it is also known as painful urination. In addition, you can recognize it by the signs and response of your puppy while urinating, including dribbling, crying out in pain, straining, continuous licking of the genitals, or even passing mucus, bloody urine, or blood clots in severe cases;
4. Incontinence. It means your pups fail to control the bladder. In other words, they don’t even become aware of the beginning of the end of the urination. If your dogs have urinary leakage, it is best managed by your veterinarian;
5. Psychogenic polydipsia. This condition can make your pup Drink lots of water and urinate frequently. However, it is often considered a mild condition that needs no treatment;
6. Bladder stones. Just like people, dogs may suffer from bladder stones. If your pup frequently passes a small amount of urine each time, urinary calculi is one of possible causes. The stones or crystals are mainly formed due to the clumping together of the minerals in the urine;
7. Bladder infection. If the amount your puppy urinates is very small, it may be a bladder infection. In this case, bacteria are often the culprit since it irritates the bladder wall to make pups feel the need to urinate more than they normally do;
8. A hormonal imbalance. Sometimes you should blame this condition for a hormonal imbalance, which provides a breeding ground for bacteria due to the urine pH changes;
9. More severe underlying conditions. They include pituitary gland disorders, Cushing’s syndrome, Kidney failure, diabetes, liver disease, complications and sequelae of Lymphatic Filariasis, peritoneal cavity fluid, and so on. They are not likely, but they are possible.
