Just like us, dogs can develop different types of bladder stones under specific conditions. Today, we'll focus on calcium oxalate bladder stones, a common culprit that demands our attention.
Meet the Oxalate Offenders
These sneaky stones tend to have a preference for male dogs, affecting approximately 73% of cases. Certain breeds, like miniature schnauzers, Lhasa Apsos, Yorkshire terriers, miniature poodles, Shih Tzus, and Bichon Frises, seem to be at higher risk. Moreover, the prime time for stone formation is usually between ages 5 and 12 years.
The Detective Work: Identifying the Culprits
To sleuth out whether your pooch is grappling with calcium oxalate stones or another kind, a urinalysis can provide a clue. However, the only surefire way to confirm the stone's identity is through laboratory analysis of the stone itself. The University of Minnesota Urolith Center can be your go-to for this service. In some cases, flushing the bladder through a process called voiding urohydropropulsion may yield the stone sample required for testing. But when the stones are too stubborn, surgical removal becomes necessary.
The "Why" Behind Stone Formation
Genetics play a significant role in the formation of these stones, as there is a substance called nephrocalcin in urine that's naturally supposed to inhibit calcium oxalate stone formation. Unfortunately, some dogs, like Miniature Schnauzers, may have a genetic flaw in this area. Other breeds, such as English Bulldogs, have a hereditary predisposition that can trigger earlier stone development. Moreover, certain metabolic diseases or medication usage can increase the risk. It's a complex conundrum, indeed!
The Art of Prevention
Prevention is key, and it starts with diet. While special diets won't dissolve existing stones, they can help prevent new ones. Aim for a diet that minimizes calcium and oxalate content and maintains a urine pH that discourages stone formation. Commercial specialty foods tailored to this purpose are available but don't worry, we won't leave your pet without treats! Acceptable treats include plain, cooked chicken, turkey, eggs, rice, peas, pasta, white potatoes, cabbage, cauliflower, bananas, and melons.
Monitoring is Vital
Once the stones are removed, the prevention game continues. Regular monitoring through urinalysis and radiographs is essential to track urine-specific gravity, pH levels, and the presence of any new stones. The goal is to catch any developments early, as timely action can make all the difference.
An Arsenal of of Preventative Measures
To further fortify the defense against recurrence, your veterinarian may recommend potassium citrate pills. These pills elevate citrate levels in the urine, which helps inhibit calcium oxalate stone formation. Additionally, thiazide diuretics may be prescribed to reduce calcium content in the urine.
Preventing Male Dog Obstruction
In male dogs, a bone called the os penis surrounds the urethra in the penis, making it susceptible to blockages from stones. To prevent emergencies, a surgical procedure called urethrostomy can be performed. This creates a new urinary opening near the scrotum, allowing urine to pass without encountering the os penis. Neutering is usually done along with this procedure, and the scrotum may be removed.
Facing the Challenge with Care
Calcium oxalate bladder stones may be stubborn, but with careful adherence to prevention measures, regular monitoring, and a touch of detective work, we can give our furry friends the best chance at a healthy and stone-free life! Remember, preventing recurrence is far easier than treating it repeatedly. So, let's stay vigilant and keep those bladder stones at bay!
Laser Lithotripsy: A Cutting-Edge Option
For selected cases, a novel technique called laser lithotripsy comes to the rescue. This involves using a laser to break the stones into small, passable pieces. It's especially handy when dealing with a small number of stones or those lodged in the urethra. Though it may not suit all scenarios, it offers a less invasive approach when applicable.
Fellow pet parents, keep your eyes peeled, embrace the preventive measures, and let's keep our precious pups free from this stone-induced mystery! With expert veterinary care and a touch of loving attention, we can conquer the challenge of bladder stones and ensure our fur babies live their happiest and healthiest lives.
