Bladder And Kidney Stones

Judge rules against prescription dog food companies

Rewards 12.5 Million judgement

Stones cause lots of concerns for dog owners. We seem to be seeing an increased incidence over the last several years. I believe due to the widespread use of dried, processed kibble.

Dr. Donald Strombeck, DVM, PHD and professor emeritus, at the University of California, Davis School of Veterinary Medicine has over 50 years of clinical experience in small animal practice. He stated, ‘The quality of pet foods may be the most important factor in many common medical and surgical problems. Before 1950, when pet owners seldom fed their pets commercial pet foods (they fed them mostly owner-prepared foods), the incidence of gastrointestinal problems was much lower than it is now.’

Stones are painful, potentially dangerous and frustrating to treat.

What are they?

In dogs and in humans, the composition and development of stones are similar. They are usually made up of mineral salts that occur naturally in the body. Minerals like calcium, magnesium, ammonia, phosphorus  and carbonates. These produce stones similar to the texture of limestone.

There are 2 major types of stones, sometimes called calculi or uroliths.

1. Struvite

2. Oxalate

Both of these have different causes, treatments and risk factors.

Let’s start with the most common form, struvite stones.

What causes Struvite Stones?

Bacterial infection is the culprit in this case.

Normal pH in the urine of healthy dogs is slightly acidic. With 7 being neutral, we would like to see a dog’s urine at between 5.5 to 6.5. Anything over  7 means the urine is alkaline. In an alkaline urine, minerals tend to clump together, they don’t dissolve like they do in an acidic environment.

Bacteria do 2 things.

1. When  they decompose, they make the urine more alkaline.

2. They provide a target for stone formation. Minerals cling to these small debris-like particles and form stones.

Risk Factors

– 85% female dogs due to short urethraurate_bladder_stones_in_dogs

– small breed females

– presence of urinary tract infection

– older dogs with decreased immune response who are more prone to bladder infections

– dehydration

– fewer opportunities during the day to go outside for potty breaks

Prevention and treatment

The number one factor is dehydration. Diets made up exclusively of processed foods like kibble are very dehydrating. They concentrate the urine and increase the likelihood of infection and stone formation.

Dr. Dennis Chow presented a paper at the 2004 Small Animal Proceeding Symposium of the American College of Veterinary Surgeons wrote, “Water may be the most important nutrient to prevent recurrence of stones. “

Water dilutes the urine creating less concentrated minerals.

Frequent urination also is extremely important. Please don’t allow your dog to go all day without a chance to pee!

Feeding a fresh whole food diet dilutes the urine.  Most moist foods are at lease 70% water compared to kibble which is a mere 10%. Kibble also is high in refined carbohydrates which contribute to an alkaline urine creating the perfect environment for stone formation and infection.

Fresh ingredients and a better quality food help with overall immune system health and provide less stress on the kidney and bladder.

If your dog has a tendency towards bladder infections, I always suggest monitoring your dog’s urinary pH. It sounds complicated but all you need are human testing strips that can be purchased online. Since pH can vary throughout the day, test at the same time each day. I recommend first thing in the morning. Simply place the strip under the dog as she pees or you can collect it in a clean pie plate. Follow the instructions on the testing strip package and in no time, you’ll be a pro.

Checking pH is important if your dog is prone to urinary tract infections(UTI’s). You can see if the urine stays acidic or creeps up. That way you can have the urine tested for bacteria.

PH monitoring also helps to see how your dog reacts to her food when no infection is present. As long as the pH stays acidic there is no need to alter her diet.

Always have your dog treated for the underlying bacterial infection.

Oxalate Stones

What causes Oxalate stones?

Oxalate is a metabolic by- product produced in the body. About 50% is produced naturally and 20-50% comes from the diet.

These stones form more often in an acidic urine. Research still has not found a good explanation as to why. Some dogs are genetically predisposed to this stone formation and there are theories that have not been verified.

An interesting statistic is that in 1981 (according to the Minnesota Urolith Center) 78% of stones struvite and 5% were oxalate. As of 2006, 39% were struvite and 41% were oxalate.

Risk Factors

Generally, these occur in male dogs.

Risk factors include:

dehydration the most important factor

– obesity

– sedentary lifestyle

– neutering

– drugs like antibiotics and prednisone

– diuretics

– Cushing’s Disease

– stress

My personal theory for an increase in oxalate stones is due to the increased use of anti-inflammatory drugs used to treat arthritis, allergies, inflammatory bowel disease and anything that itches.

Prevention and Treatment

Most dogs with oxalate stones due need to have surgery to remove them. There are other methods that need to be discussed with your veterinarian.

Prevention is another matter. There certainly is controversy around diet and oxalate stones but everyone agrees that water and a moist, whole food diet it best. No kibble!

Keeping the body hydrated and the urine dilute is the most important factor. Change the water in the bowel frequently. Consider a dog fountain. They love to drink out of the hose and this is the next best thing.

Do make sure your dog has frequent potty breaks.

It is a good idea to supplement with B complex vitamins, probiotics and potassium citrate(this can raise the urinary pH, making it more alkaline). As with struvite stones, it is wise to monitor urinary pH.

Include meat, eggs and dairy in the diet while avoiding high oxalate content foods like spinach and sweet potatoes. Do keep in mind that boiling vegetables does lower the oxalate content so raw vegetables are naturally higher.

You know your dog best. If he appears lethargic, seems to want to pee more frequently with very little output, has accidents in the house  or has blood in his urine, get him to the vet.

As with most things in life, it may be more difficult to feed a whole food diet but the results on your dog’s health are worth it. Help reduce the possibility of stone formation by keeping your dog hydrated. Feed a good quality nutritious food and avoid processed kibble as much as possible.

Yours in good health,

The use of Presciption dog food is one of my pet peeves and shows that the
phrase “Marketing over Mother Nature’ holds true.
If you are a dog owner, you may have heard about the class action suit
against prescription dog foods. Hills, Science Diet, Royal Canin and Purina
are some of the brands that are accused of misleading consumers and
veterinarians about the benefits and ingredients of their products. The
lawsuit claims that:

  • these companies charge premium prices for prescription dog foods that are not significantly different from regular dog foods. In fact, they are made in the same facilities, using the same suppliers as low-quality grocery store brands like Alpo and Beneful.
  • they do not have any scientific evidence to support their claims of treating or preventing various health conditions in dogs. They are not made in facilities that follow traditional drug manufacturing protocols.
  • that these companies have violated consumer protection laws and engaged in false advertising.

The class action suit was filed in 2019 by a group of dog owners who purchased prescription dog foods from these brands for their pets. They are seeking refunds, damages and an injunction to stop the companies from selling prescription dog foods without proper authorization and
disclosure
. The suit is currently pending in the U.S. District Court for the Northern District of California.

Prescription dog foods are supposed to be specially formulated to address specific health issues in dogs, such as kidney disease, diabetes, allergies, obesity and more. However, according to the lawsuit, these products are not
regulated by the Food and Drug Administration (FDA) or any other agency,
 and they do not require a prescription from a veterinarian to be sold.

The lawsuit claims that these companies have exploited this loophole to market their products as prescription dog foods, even though they are not approved or tested by any authority.

This suit also accuses these companies of using low-quality ingredients and fillers in their prescription dog foods, such as corn, wheat, soy, by-products and artificial colors and flavors. These ingredients may not only be ineffective for treating or preventing health conditions in dogs, but they may also cause adverse reactions and allergies in some dogs. The lawsuit cites several examples of dogs that suffered from health problems after
consuming prescription dog foods from these brands, such as vomiting, diarrhea, weight loss, skin infections, kidney failure and death.

The lawsuit seeks to hold these companies accountable for their deceptive and unlawful practices, and to provide compensation and relief to the dog owners who have been harmed by them. It also aims to protect the public interest and the welfare of dogs by ensuring that prescription dog foods are properly regulated and labeled, and that consumers and veterinarians are informed about their benefits and risks.

Please be aware that the FDA does not review or verify the health claims on any veterinary diet.

Take a close look at the ingredient list and ask your vet for evidence that the foods in the prescription diet are any better than most regular diets. Also please keep in mind that while your vet has the best intentions, they get little or no nutrition training and often what little training they do get comes from the very companies that are named in these lawsuits. 

Ultra processed foods made with poor quality ingredients are not what your dog needs if they are suffering from an illness. Give your dog a fighting chance with fresh, quality foods for a long and healthy life. 

This lawsuit was settled in July of 2021. Hills Pet Food paid $12.5 million to participants.
