Cranberry supplements for dogs are among the most talked-about supplements that you can find in stores, both physical and online. Dog cranberry supplements are special formulas made from cranberry extract or juice. The cranberry fruit is known for preventing and treating Urinary Tract Infections in dogs and promote overall urinary health.

An interesting study took a dozen of dogs with a history of recurring UTI. The subjects were administered cranberry extract over weeks. None of the dogs developed a UTI thereafter.

There are a lot of speculations around dog health supplements in general. So let’s take a look at what dog cranberry supplements are all about along with some of the product recommendations!

What are dog cranberry supplements?

Cranberry supplements for dogs naturally prevent and treat UTI and bladder stones while improving the dog’s overall urinary health. These supplements are available in various forms; e.g. granules, powder, and pills. Your dog can either consume the supplement directly or have it mixed with his foods.

Cranberry additives are completely safe for dogs. Indeed, they are a great source of antioxidants and Vitamin C – both of which are effective for a dog’s internal health. They contain some other key ingredients such as probiotics in moderate quantity which are safe too. Cranberries are also part of many healthy dog foods.

While buying cranberry supplements for your dog, especially in the pill form, make sure that the product is specially formulated for dogs.

When are dog cranberry supplements used?

The use of a cranberry supplement for your pet is recommended in the following situations.

For UTIs in Dogs

Cranberry supplements are ideal home remedies for dogs suffering from UTI. Urinary tract infection or UTI is not just a human medical problem. It can affect dogs too and nearly 14% of dogs will expectedly suffer from this infection at least once during their lifetime.

Although it is always advisable to seek veterinary attention just as your dog shows some symptoms of UTI, a natural home remedy that even vets suggest and recommend comes in the form of a cranberry supplementation formulated for dogs especially.

So, let’s first understand why dogs suffer from UTI.

Both good and pathogenic bacteria invade your dog’s urinary tract and are usually flushed out through urine. At times, some harmful bacteria cling to the bladder lining and other urinary tract spots including the urethra, ureters, and kidneys. These bacteria disrupt the proper functioning of the tract leading to symptoms like frequent urination, burning sensation, blood discharges, tendency to lick the genital area and so on.

Now, cranberries along with few other types of berries contain substances called the proanthocyanidins. These are compounds that prevent the E.coli, the main harmful bacteria, from clinging on to the lining of the bladder. Thus, the bacteria are flushed out and unable to cause the infection. Cranberry supplements for dogs work well in washing away all impurities in the bladder, thereby, promoting a sound UT health.

While proanthocyanidins are effective as a molecule, its oral bioavailability is incompletely defined for most species.

For Dogs with Bladder Stones

Urinary tract infections, ongoing or frequently reoccurring, lead to the formation of struvite stones and crystals, also known as the bladder stones. The symptoms are somewhat similar to those of UTI although they can be more severe. Some of these are an urge to urinate but little urine, strain during urination, urine accidents, etc.

Cranberry supplements for dogs are an effective treatment for bladder stones as well. Since the stones are mostly caused by the UTI itself, the supplements can prevent them from forming. Also, the regular dosage of the supplement dissolves the bladder stones, thereby, eliminating the need for surgery. (Obviously, do not come to these conclusions by yourself as seek a veterinarian’s opinion for your dog’s specific case).

To reduce plaque build-up

Although not what cranberry supplements for dogs are popularly known for, they can also help clean the teeth and reduce plaque buildup in dogs. Your dog’s dental health is important and the formation of dental plaque is a major reason behind tooth decay and bad dog breath.

Plaque is the accumulation of bacteria-made bio-film growing on the surface of the dog’s teeth causing loss of teeth, poor appetite, and other infections.

Cranberries and cranberry supplements contain a good amount of flavonoids and polyphenols. These two molecules precisely reduce the formation of dental plaque. Therefore, a cranberry supplementation works well in improving the dental health of dogs.

What to look for in cranberry supplements for dogs?

sugar in dog cranberry supplements
Check that dog cranberry supplement you buy does not contain any added sugar.

First and foremost, it is important to be aware of the right amount of cranberry that your dog should consume, depending on his size and diet. The ideal dosage is:

  • 100 mg thrice a day for small dogs
  • 200 mg thrice a day for medium-sized dogs
  • 300 mg thrice a day for large dogs, and
  • 400 mg thrice a day for giant dogs.

To make sure you are buying the best cranberry supplements for dogs, you must look for a few factors.

Sugar content

One downside of cranberry supplements for dogs is their high sugar content. However, an optimum amount of sugar does no harm to your dog.

Make sure that the supplement you buy does not contain any added sugar. Excessive sugar causes several problems like diabetes, obesity and so on. After all, there is no point in making your dog vulnerable to other health hazards in the process of treating their UTI.

Fruit concentration

The concentration of cranberries present in the supplement varies with different brands and different forms of the supplement.

As a standard estimate, vets often recommend administering 0.5 milliliters of cranberry juice per pound of body weight. Alternatively, 10 milligrams of cranberry extract is considered suitable per pound of body weight each day.

So, to give the right dosage of the cranberry supplement to your dog, you will have to consider the concentration of cranberries as well as do some calculations based on your dog’s body weight. Make sure the dog scale is accurate!

Presence of other vitamins

Cranberry supplements for dogs contain other ingredients and vitamins, out of which Vitamin C is present in a good amount. But much like sugar, the vitamin C concentration should also be checked and consulted about with your veterinarian. This is because fortified Vitamin C often increases the risk of your dog developing kidney stones in the long run.

Brand value

A good brand like that of the Spring Valley or the Vet Classics will certainly assure you of the quality of the supplement you buy for your dog. Also, cranberry supplements for dogs from reputed brands will typically be manufactured in the US and will contain less sugar and no additives and preservatives whatsoever.

We will soon discuss the top 10 cranberry supplements for dogs from well-known brands in the following sections.
