Can dogs eat green grapes or raisins?


As omnivores, dogs must have a balanced and diverse diet. In most cases, this includes a source of fresh vegetables and fruits, whether offered as a healthy gift or included in your pet's homemade food. However, not all human foods are safe for dogs to eat, in fact, some of them are frankly toxic to our four-legged friends. If you are here because you have been wondering if dogs can eat grapes, you should know that this is one of the few fruits that should never be given to pets. Even a single grape can be fatal to dogs, so even a small bite is a big no-no.

Unlike safe fruits for dogs, such as strawberries, apples or bananas, grapes are highly toxic to dogs. The toxicity of the grape can affect any dog, regardless of its breed, age, sex or size, and the consequences are, in most cases, very serious. However, not all dogs will react in the same way with grapes, but for some, eating grapes can cause kidney failure.

Can dogs eat grapes? What about raisins?

Again, let's sum it up: can dogs eat grapes? Absolutely not. Never, in any form or form, give your pet grapes. Now that we've clarified that, let's turn to the reasons why dogs can't eat grapes.

Oddly enough, while the cases of dogs poisoned by eating grapes are well documented, scientists have not yet been able to find out the exact substance in this fruit that makes dogs sick. In fact, there is not even a uniform reaction of the dog to this fruit, apart from the fact that they are generally negatively affected by it, although at varying levels. Some dogs seem to have better results than others, with grapes that cause "only" vomiting and diarrhea, while unlucky dogs that are especially sensitive to the mysterious toxic substance in grapes can experience fatal complications, such as acute renal failure, violent seizures and coma

We cannot say, with certainty, what is the reason for the different side effects that the dog has when eating grapes. What experts can say, however, is that it seems that the toxic substance is found in the meat of the fruit, instead of its skin or seeds, indicating that no form of grapes could be safe for dogs.

While there is no doubt about the possibility of dogs eating grapes, you may be curious about raisins. Seeing how raisins are dehydrated, the same rules apply: dogs cannot eat them. In fact, some experts claim that raisins can be even worse for your dog, since the harmful substance will concentrate even more on the dried version of the fruit. And, again, even the small amount of a few raisins is enough to harm a dog, especially if the dog in question is particularly sensitive.

As is usually the case with, well, everything, there are people on the Internet who claim that the toxicity of the grape is a hoax and that dogs can eat grapes without having any problem. The problem with this is that the specific substance in this fruit that is making dogs sick is still unknown, which means that it could be that the grapes are not poisonous to dogs, but the chemicals used in the treatment of diseases of the fruit. Even if herbicides and pesticides were the cause of the problem, it is the same: it is very likely that most of the available fruit has been treated with the same infusions. So, please, do not take a risk, because it is completely unnecessary to do so, there are many other safe fruits for dogs that you can offer your pet.

Symptoms of grape poisoning in dogs

What happens when a dog eats grapes? Since this fruit is highly toxic to dogs, your pet may experience some serious health problems if consumed. However, while it is true that there is something about grapes that makes them dangerous for dogs, not all four-legged partners react in the same way to grape poisoning. Some pets may shake with milder side effects, such as an upset stomach, while some dogs barely live to tell the story after eating only a grape or two.

According to PetMD, here are the most common symptoms that your dog will show if they eat grapes or raisins:

  • Vomiting and (or) diarrhea
  • Loss of appetite
  • Lethargy, weakness, unusual stillness

  • Dehydration
  • Oliguria (passing only a small amount of urine)

  • Bad breath
  • Oral ulcers
  • Tremors
  • Seizures

Of course, if your dog already did it on his own, you won't have to have it repeated. At this point, you should contact a veterinarian for advice on the best way to proceed. In most cases, you will have to take your pet to the emergency veterinarian, for gastric lavage or administration of activated charcoal, which are intended to counteract the toxicity of the grapes. After that, check your dog for See if they show any of the symptoms of kidney failure is vital, you should do it for a few days.

At the slightest sign of kidney related problems, such as urinary problems, rush your pet to the veterinarian immediately.

Grape poisoning treatment

Depending on how severe the poisoning is, your veterinarian may suggest different courses of treatment. At best, all of your pet's problems would be gone in the initial stage, after the grape was vomited and the toxins removed quickly. A good rule of thumb is that a dog that does not show any of the most severe symptoms and does not have any subsequent symptoms of kidney failure in the next three days is clear. For dogs that are not so fortunate, treatment can range from intravenous fluid therapy that removes toxins from the bloodstream and encourages the dog's kidneys to work at a healthy pace, until hemodialysis. Unfortunately, it is not uncommon for a veterinarian to have to sacrifice a dog that ate grapes, because their kidneys were completely closed. However, this serious scenario is more likely in cases where no one noticed that the dog was eating grapes and did not notice the symptoms of kidney failure until it was too late.

Tips to prevent grape poisoning in dogs

It is quite simple, really. Stay away from sharing a bite of your fruit salad, raisin cookies or a sip of grape juice with your stuffed animal bestie. In addition, you should try to avoid having grapes in easily accessible places, if you wish, place them in the refrigerator or eat them immediately, instead of leaving them on the kitchen table or in the closet. Of course, these tips sound as if they came directly from the Obvious Captain, but, in truth, the most obvious solutions are what we tend to overlook first. If we eliminate the instances in which pets received grapes directly as a gift, most cases of poisoning occurred when a puppy stuck its leg in the owner's fruit stash that was free (such as a bowl of fruit on the table from the kitchen) or when they inadvertently shared some of their food that coincidentally contained grapes. Therefore, be careful and keep your pupper safe!
