Dogs may pee more often as a result of a change in the environment like hot weather (which makes the dog drink more and therefore urinate more). A recent change in the dog’s diet could also cause more frequent urination.
But other times frequent urination is an illness symptom of some underlying health problems. In fact, one of the common urinary problems in dogs is frequent urination.
The bottom line is, if your dog is house-trained but has suddenly started to urinate more excessively and frequently, try to see if there has been some recent changes in your dog’s lifestyle, and at the same time pay more attention to his physical health conditions.
Below is a list of health problems and other possible factors that may cause frequent urination in dogs. If you suspect that your dog is suffering from any of these problems, get him to the vet for a proper diagnosis.
Diseases that Cause Dog Frequent Urination
Any of the following health problems can cause dog frequent urination:
Bacterial infections of the bladder can cause frequent urination in dogs – but every time the dog urinates, usually only a small amount of urine is passed.
Dogs with bladder stones also urinate frequently. They usually have to strain to urinate due to pain and the urine may contain blood.
Bladder stones can cause partial or complete blockage of the urethra which is a serious problem and requires immediate veterinary attention.
Dogs suffering from chronic kidney failure drink water excessively. The result? They urinate frequently and excessively.
The color of the urine is usually rather pale. Other signs and symptoms of canine kidney failure include dehydration, appetite loss and weight loss, depression, and dry haircoat.
Diabetes mellitus (sugar diabetes) also causes a dog to drink more water and urinate more frequently. Other symptoms of canine diabetes include a gain in appetite but weight loss.
Cushing’s disease causes a dog to eat and drink more, and urinate more frequently.
Other typical signs include a sagging pot belly, excessive panting, and hair loss. Most cases of Cushing’s disease are due to tumors in the pituitary gland.
Some canine liver diseases such as liver shunt or inflammation of the liver cause a dog to drink more, which again results in frequent urination. Other symptoms associated with liver disease in dogs include appetite loss, lethargy, diarrhea, and vomiting.
Bladder tumors (usually transitional cell carcinomas) are rather aggressive and cause symptoms similar to a bladder infection, such as frequent urination, blood in urine, and straining to urinate.
If your dog shows any of the above symptoms, be sure to get to the vet for a proper diagnosis.
Prostate cancer is rare in dogs but is aggressive and invasive. It causes enlargement of the prostate resulting in symptoms such as frequent urination, straining to urinate, and blood in urine.
Other symptoms include constipation, walking in an abnormal gait, fever and lethargy.
Vaginal tumors (usually occur in older female unspayed dogs) can also cause frequent urination. Other symptoms associated with this problem include vaginal discharge or bleeding, a mass protruding through the vulvar lips, and frequent licking at the vulva.
Other Possible Causes of Dog Frequent Urination
Besides the above diseases, dog frequent urination can also be caused by:
Some forms of poisoning – methylxanthines (chocolate) and organophosphates (poison baits) – can cause frequent urination in dogs.
Rather than a physical problem, psychogenic polydipsia is a behavioral problem – the dog exhibits the obsessive-compulsive behavior of drinking water frequently and excessively, which naturally results in increased frequency in urination.
Exactly why some dogs do that is unclear, but many veterinarians believe that it is due to some form of stress or just simply boredom, and suggest distracting the dog from the obsession by games and long walks.
Dog Diapers and Toilet for Frequent Urination
To prevent “accidents” from happening at home, consider getting some doggie diapers for your dog if she has to urinate often but may not have the chance to go outside as frequently as needed.
You may also want to consider getting an indoor toilet such as this PUPPYPRO Puppy Dog Potty Toilet for nighttime use, or even for daytime if your dog is often left home alone.
