Is It Safe for Dogs to Eat Blueberries?

Dogs have taste buds that can detect the sweetness, sourness, and bitterness of food. However, since the dog's wolf ancestors ate mostly wild meat with high salt content, taste receptors for saltiness never developed as well as other canine taste buds.

Dog owners who have ever given their dog a sweet-tasting snack know how much their dog loves those snacks. But should a dog be given sweet fruit like blueberries? Although blueberries are considered a healthy "superfood" for humans, is it safe to give a dog blueberries?

Blueberries contain antioxidants, fiber, and other phytonutrients beneficial to a dog's general health. They do not contain substances toxic to dogs found in chocolate or raisins. So, yes, it is safe to give a dog blueberries--but only in moderation.

Limit the number of blueberries a dog eats to a small handful every few days as a treat. The problem with allowing a dog to eat as many blueberries as they want involves their gastrointestinal system. Diarrhea, an upset stomach, and vomiting are symptoms that a dog may have eaten too many blueberries.


Health Benefits of Blueberries for Dogs

Antioxidants are powerful molecules that counteract the oxidation of soft tissues. Oxidation is a serious type of degradation to tissues resulting from aging, stress, diet, and pollutants. Antioxidants help reduce and delay oxidation caused by free radicals. Blueberries and other berry fruits are rich in antioxidants and may prevent the development of canine diseases such as cancer, stroke, and immune system disorders.

Blueberries may also enhance a dog's cognition and general brain health. Antioxidants help slow the degenerative effects that aging has on a dog's brain and could reduce the risk of canine dementia in dog breeds prone to dementia, such as German Shepherds, Labradors, and other larger dog breeds.


How Many Blueberries Should Dogs Eat?

Begin acclimating a dog's digestive system to blueberries by giving them three or four blueberries in the morning. Monitor the dog's bowel movements later in the day to see if the blueberries have given the dog watery stools or diarrhea. If so, reduce the number of blueberries to two until the dog no longer has loose stools.

However, some dogs may never get used to blueberries. If gastrointestinal problems persist after two or three days, stop giving the dog blueberries and make sure the dog's stool returns to normal.


Can Dogs Eat Other Berries Besides Blueberries?

Yes! Strawberries and blackberries are also safe for dogs to eat. Like most berries, strawberries and blackberries contain the same rich amounts of antioxidants and phytonutrients beneficial to a dog's physical and cognitive health.

Strawberries even have a bonus benefit. They contain enzymes that help keep a dog's teeth white. Freeze a bag of strawberries and give them as a nutritious, crunchy snack to your dog in between meals. But remember to start off a dog with only one or two strawberries to allow his digestive system to get used to the fiber in berries.

Depending on the type of ailment a dog is recovering from, owners should avoid giving their dog treats of any type until a veterinarian says the dog is fully recovered from an illness.

Although blueberries provide numerous health benefits for dogs, they contain many phytonutrients that could reduce the ability of medications to treat a specific illness. Additionally, the extra fiber provided by blueberries may worsen intestinal disorders causing loose stools and diarrhea.

Feed dogs that are recuperating from an illness only what the veterinarian recommends.

Avoid giving whole blueberries to dogs with missing teeth or to dogs that cannot chew properly. The smallness of blueberries presents a choking hazard to dogs that are unable to chew their food properly.

Dog owners can still give dogs that can't chew normally blueberries if they make an easy-to-swallow paste out of mashed blueberries. Dogs can then lick the blueberry paste out of a bowl or off their owner's finger.
