Dogs are carnivores by nature, but their adaptability to new circumstances has allowed them a rather successful absorption of plant-based foods like some fruits. These vegan products provide excellent variety for the dog. However, not all food is safe for dogs. Plenty of studies have shown that many common substances are poisonous to pets. So, let’s see what is in with the grapes.
Are Grapes Safe For Dogs?
Grapes are sweet, ball-shaped green or purple fruits eaten by humans in many different ways. We consume grapes, raisins, grape juice, and wine. But can dogs also enjoy the taste of grapes? Unfortunately, no.
Dogs can’t eat grapes, which can be toxic to them, as confirmed by some scientific articles. This is true for both grapes that are fresh and raisins. Grapes are bad for dogs because they can damage the kidneys, leading to complications, including acute renal failure. Symptoms described included vomiting several hours after ingestion, anorexia, diarrhea, lethargy, and abdominal pain. Hence, never feed your dogs grapes, and never let them eat these fruits at home or in the garden.
Can Dogs Drink Grape Juice?
This info lets you know that dogs can’t eat grapes. But can they drink it? Can dogs eat any form of the fruit? Drinks like wine or grape juice are dangerous for dogs. Exercise extra caution with wine and alcoholic goods. Dogs may be attracted to alcoholic drinks when left unsupervised. But these animals are unable to process ethanol and are very sensitive to even small amounts, so do not give them such drinks!
Studies have confirmed that grape seed extract is the only grape product that is not toxic to dogs. Long-term administration of a polyphenol-rich grape and blueberry extract mixture to dogs is not associated with renal or hepatic injury and is, therefore, safe. The extract also showed health benefits such as improved cognitive function.

Summary
Can dogs eat grapes? No. Can dogs drink grape juice? No. This is part of your learning, so never give such products to your dog, as they can cause severe harm to your pet. It is also advisable to consult a veterinarian if you want to introduce your dog to new products.
