Excessive urinating is only one of the symptoms of a bladder infection in dogs, but it is an important one.
The bacteria, stress, irritation and pressure on the bladder causes your pet to feel an urgency to urinate often.
Either very little urine will be produced or none at all.
However excessive urinating is not the only symptom.
There can be;

• Loss of appetite
• Pain
• Blood in the urine.
  This is often not noticed by the naked eye and often requires a urine specimen
• Foul smelling urine
• Dehydration and excessive thirst especially if it is cold or he is not exercising

If the bacteria have gone further up the urinary tract, the symptoms can be much more severe and can also result in kidney involvement.
These symptoms are;

• Nausea
• Vomiting
• Fever

Take your dog to the veterinarian if he is experiencing any of the symptoms of bladder infection in dogs mentioned.
Once the bacteria is under control by the usual course of treatment, namely antibiotics, it is time to evaluate and understand why your dog had or has a UTI and take steps to prevent future outbreaks which often happen because UTI's are usually a result of diet, lifestyle, immune function or even a birth defect in the urethra.
Steps to take for his or her future health should include:

• Plenty of high quality food
• Clean water
• Exercise daily along with human companionship
• Supplements to support his or her immune system

Natural remedies, especially ones made specifically for pets, and targeted towards the health result desired, can strengthen your dog's immune system.
There are many natural products that provide antibacterial and anti-inflammatory ingredients reducing inflammation which has been proven to aggravate the body as a whole, our health as well as our pets.
Maintaining overall health is your best friend's defense against disease and age- related problems.
