Humans that housed dogs in communities could’ve also shared these fruit delicacies as yummy treats for their furry friends. Although cranberries have always been a popular and healthy human snack, lots of dog owners want to share them with their pets nowadays. 

This is especially during the holidays. So it should come as a pleasant surprise that cranberries are perfectly safe for dogs, provided it is served in moderation.

So you need to make sure that your cranberry stash is out of reach and in a safe and secure place that Fido can never get to.

Cranberries tend to have a sour and tart taste, and if you’ve eaten them yourself, you already know this. So you can imagine sour isn’t exactly a familiar taste to dogs, neither is it one that pleases their palate.

Cranberries and Canine Urinary Problems

Bladder and urinary tract infections are quite common in canines especially those that have been spayed. These infections are likely to occur when bacteria enter the bladder and urethra and settle in. If you find that your dog is frequently urinating and experiencing pain while doing so or has blood-tinged, cloudy, dark, or foul-smelling, then a urine infection may very well be the culprit. 

This condition can be quite serious if it’s left untreated and travels to the kidneys. While there is not much evidence supporting the fact that cranberries can cure UTI in progress, some vets do recommend cranberries as a preventative measure for dogs who seem to be prone to UTIs. 

Ultimately, the urinary infection must be treated with antibiotics. However, this is how cranberries can assist in the process. 

It is known that bacteria thrive in alkaline urine or urine containing a high pH, and the cranberries increase the acidity of the urine, making the environment less hospitable for bacteria to thrive. It’s also been said that cranberries prevent bacteria from sticking to the bladder wall, therefore eliminating the chance of an infection occurring.

Cranberry Therapy

It’s always a good idea to speak to a veterinarian prior to attempting to treat your dog’s urinary tract problems on your own. If you find that your dog frequently has urinary tract infections and you are considering cranberry as a treatment option, consult with your vet. He will know what’s best for your dog and advise you whether he thinks that cranberry therapy should be used in the first place. 

It’s also important to remember that urinary tract infections can be treated with antibiotics. Cranberry supplements may come in handy for preventing dogs with recurring urinary infections. However, as is the case with all other supplements and or medications, consultation with your vet is imperative prior to starting any form of treatment on your dog.

Dried Cranberries contain as much as 20 g of sugar, and that’s equivalent to a small glass of soda. However, studies show that dogs have more consistent blood sugar levels when placed on low glycemic diets. Ultimately, like adults, when dogs indulge in too much sugar, it can lead to diabetes. 

So steer clear of store-bought cranberry products, and this includes cranberry juices that may contain as much sugar as dried cranberries if not more


So we’ve established that dogs can have cranberries and they are safe as well. Dogs can also benefit from cranberry extracts in the form of supplements, chewable pills, and powders, provided they are dog-friendly products.
