What others say about it:

My 6 month old puppy used to pee like every 30 minutes-1 hour. I’m not exaggerating when I say she’d pee 5 minutes after a long walk and then again 30 minutes later. People (even her vet) told me it was due to her small bladder, but I thought she’s a small breed puppy, so 6 months is long enough for her bladder to have grown to nearly a full adult size. I decided to try this antioxidant after looking at the reviews. IT WORKS LIKE A CHARM! My puppy pees about 4-6 times a day now and I think this is how a healthy puppy pees.

Best Cranberry Supplements: Buying Guide & FAQs

Cranberry supplements are usually given to dogs with urinary tract infections because cranberry contains a certain substance that helps prevent the adhesion of bacteria on the inner surface of the urinary tract walls. More than this, however, it provides other benefits, too. Like other pet products, not all dog cranberry supplements are the same. That’s why you need to know how to pick the right one.

What Makes Cranberries So Healthy?

Harvest fresh red cranberries in wicker basket selective focus Autumn concept

There are many reasons why cranberries can be very healthy for both you and your pet. First, cranberries contain more than two dozen phytonutrients that give this berry its amazing antioxidant properties. It is through the presence of these phytonutrients that cranberries can also help reduce the levels of triglycerides and sugar in the blood while also reducing the accumulation of fat in the dog’s body.

These berries are also known to contain a class of polyphenols known as proanthocyanidin. This substance is believed to play a role in preventing the adhesion or attachment of bacteria, toxins, and other harmful substances to the epithelial lining of the inner wall of the urinary tract from the ureters to the bladder and the urethra. Apples, especially Granny Smith and Red Delicious varieties, contain more proanthocyanidins than cranberries or other food except for cocoa beans.

In addition to proanthocyanidins and anthocyanidins, cranberries also contain ellagic acid, which some experts believe can cause cancer cell death. It is also low in calories at only 46 calories per cup and contains as much as 87% water, so there’s no risk of developing obesity in your pet.

Cranberries are also rich in Vitamins C, E, and K and the minerals manganese and copper for better all-around health, blood clotting, and improved immune system functioning. These also have an excellent ratio of omega-3 to omega-6 fatty acids for better anti-inflammatory and immune-boosting effects.

Benefits of Cranberry Supplements for Dogs

Aside from the fact that cranberry supplements for dogs are primarily indicated in the prevention of urinary tract infections, the promotion of optimum urinary tract health, and as an adjunct to the treatment of urinary tract infections in dogs, these are not the only benefits that cranberry supplements can provide for our dogs. Because of the very nature of proanthocyanidins and the other nutrients found in cranberries, you can expect the following benefits, too.

Help Prevent the Build-up of Plaque on Your Dog’s Teeth

Dental plaques are produced by bacteria present in the dog’s oral cavity. These microorganisms leave a very thin biofilm on the surface of the teeth to help shield them from being removed. Since cranberries have antimicrobial properties and an improvement in immune system functioning, there is a reduction in the number of bacteria in the dog’s mouth. While it helps, cranberry supplements are not substitutes for good dog toothpaste, dog toothbrush, and vet dental visit.

Slow Down the Decline in Canine Cognitive Functioning

This is related to the antioxidant properties of cranberries. Dogs already in their senior years may show signs of cognitive declines, such as poor memory and loss of coordination or balance. While cranberries do not treat these conditions, at the very least, they can lessen the impact of such symptoms.

Prevent Macular Degeneration

Cranberries’ antioxidant properties can also help prevent canine eye diseases such as macular degeneration. This can help reduce the risk of blindness in your dog.

Improve the Functioning of the Heart and Blood Vessels

The polyphenols, flavonoids, and antioxidants in cranberries improve the blood vessels and the heart. These substances help relax blood vessels and reduce blood pressure, which, in turn, helps relieve pressure in the heart.

Can Cranberry Supplements Help in Treating Urinary Tract Infections in Dogs?

Biewer terrier puppy with Cranberries in basket

While it is true that cranberries can help dogs with UTIs by preventing the adhesion of certain types of bacteria on the wall of the urinary tract, it should be understood that it is not a treatment for canine UTIs.

For a substance to be considered a treatment, it should be backed by solid scientific evidence. It should also be classified as such by a regulatory body. Considering that cranberry supplements do have scientific evidence supporting their claim, the absence of the second requirement prevents it from being classified as a treatment. As we have said in our other articles, supplements are not considered therapeutic agents or treatments by the FDA because no rigorous testing is involved in their classification. Supplements are also not subjected to very strict regulations.

That said, if you’re thinking of cranberry supplements as a treatment for canine urinary tract infections, you’re grossly misinformed. Only antibiotics can kill the causative organism that produces the infection. Furthermore, the scientific studies showing the benefits of cranberries only point to their effectiveness in preventing the adhesion of Escherichia coli only. As such, there is a question about how effective it will be if a different kind of bacteria causes the UTI.

However, cranberry supplements can be used to support the ongoing treatment of canine UTIs. While antibiotics kill the microorganisms causing the UTI, cranberry supplements can help prevent the adhesion of these microorganisms so that the antibiotics more effectively kill them.

Possible Risks of Trying Cranberry for Your Pet’s UTI

Generally, cranberries should be safe for your pet unless it has a very sensitive stomach. However, cranberries contain a lot of substances that can have serious effects on certain types of dogs. Here are some of the possible substances that cranberries contain and why these can be risky for your pet.


Cranberries contain what are called oxalates. The problem with these substances is that they usually form crystals or stones. If you have a pet at an increased risk for developing kidney stones, you might want to refrain from giving your pet cranberry supplements, as this will only increase the chances of forming renal stones.

Vitamin C

We all know the many health benefits of vitamin C. Unfortunately, vitamin C also increases the risk of calcium oxalate stone formation. When vitamin C is metabolized in the liver, oxalates are formed. We already mentioned above that oxalates can increase the risk of developing kidney stones in dogs. So you may be helping your dog get rid of its UTI but also increasing its risk for kidney stones.

Cranberry supplements can help your dog get through its urinary tract infection much better, especially when used with antibiotics. Its benefits are not only limited to the dog’s urinary system, but cranberries can also benefit the immune system, the cardiovascular system, the teeth, the eyes, and cognitive functioning. Do note, however, that cranberries also contain other substances that may be risky for your pet. So, before you give your pet any supplement, talk with your vet first.
