Hi XXXXXXXXX~
Inappropriate elimination can be caused urinary stones, Cystitis, Kidney Disease, Bladder Cancer, or Urinary Bacterial Infections. Urinary Stones are common and found in the kidneys, bladder and urethra though usually they are in the bladder. The formation of crystals or stones in urinary tract can be caused by the following factors usually working together: mineral crystals in the urine, bacteria, diseases, some medications, excess Vitamin C, imbalance in pH of urine. Typical symptoms are straining to urinate, frequent urination of small amounts and blood in the urine. Some breeds are known to have problems with stones. These are Miniature Schnauzer, Schnauzer, Lhasa Apso, Shih Tzu, Bichon Frise, Miniature poodle, and Yorkshire terrier. Cystitis is when your dog's bladder becomes inflamed. It is believed that infections, polyps, tumors and stones contribute to this condition, but the actual cause is unclear. Typical symptoms are straining to urinate, frequent urination, straining to urinate, difficulty urinating and blood in the urine. Kidney Disease is a common cause of non-accidental death in dogs. It is not clear what causes kidney disease but it is believed that dehydration, blood loss, impaired heart function, tumors, infections and toxins contribute to it. Some medications for kidney disease may cause blood in the urine. Bladder cancer occurs in middle-aged and older dogs. Bladder cancer is not as common as other causes such as Urinary tract infections, though it is not recognized early for that same reason. Typical symptoms are frequent urination, urinating small amounts, blood in the urine, and infections. Urinary bacterial infections can occur in bladder (most common), kidneys, urethra, and prostate. They are easily treated once diagnosed. They are the major cause of the prostate disease in male dogs. The prostate becomes inhabited by bacterial and it becomes difficult to eliminate. Some other conditions such as diabetes, cancer and viral diseases affect a dog's immune system and may contribute to this condition.
Getting him to your vet for a thorough physical examination is the best thing you can do. Try to collect a urine sample as well so that your vet can evaluate kidney function and look for signs of urinary tract infection. Since your dog is a male, allow your dog to begin urinating and when you are sure he is peeing you can slip a shallow bowl or soup ladle into the urine stream to catch your sample. Put the urine in a clean, dry container and refrigerate until your vet appointment. It's best if the sample is less than 24 hours old.
If the vet doesn't find anything wrong with your pup, and you think that this urination is due to either fear/anxiety or some other behavioral issue, you might want to consider trying him on a product that is made specifically for dogs with anxiety. In my rescue work, I use two products exclusively:
Melantonin is an over-the-counter drug that can be used to treat some anxiety issues in dogs. The dose you would give would be up to 3 mg given orally whenever necessary up to every 8 hours. More information can be found here: http://www.petplace.com/drug-library/melatonin-melatonex/page1.aspx , which includes risks, warning signs to watch out for and other bits of useful information.
Try a DAP collar. These are collars that are impregnated with a man-made version of the dog appeasing pheromone, which is a pheromone that nursing bitches give off to their pups to help them feel calm and secure. It's something that humans can't smell, but it has an amazing effect on dogs with anxiety and other issues. Although you can find them at your vet's office..you can also find them online at places like Amazon.com and Ebay for much cheaper. Just make sure they're DAP brand, as they seem to work better than some other versions
I usually start with the collar, then add the Melatonin in if I don't see any improvement within a week or so.
I hope this helps!!
