Are you wondering if you should bring your dog to the vet after your dog ate grapes? If you want to find out what you should do next, keep reading!

Grapes are dangerous for dogs, and therefore we should never give them any. Grapes can cause a number of medical issues including kidney failure, loss of appetite, weakness, vomiting, and can also lead to death.

In this post, we’re going to discuss what you should do if your dog ate a grape and what the consequences may be. We’ll also provide some helpful tips to make sure that this never happens again.

Let’s get started.

Why are grapes toxic to dogs?

My dog ate one grape - Can a single grape kill a dog

Grapes are toxic to dogs because they contain a compound called tartaric acid and can cause serious health problems. This compound can cause problems in your dog’s body, including heart failure, seizures, excessive thirst, kidney damage or failure, and even death.

The exact reason why grapes are toxic to dogs is unknown, but it is thought to be due to tartaric acid. Seedless grapes and grape juice are also poisonous to dogs.

If your dog eats grapes without showing any signs of illness, it is still important to see a vet as soon as possible.

Can a single grape kill a dog?

There is not a specific amount of grapes that a dog can bear. Every dog is sensitive to grapes to some extent. For example, some dogs can die even by taking just one grape while others can get kidney failure or other serious issues.

A grape can be lethal to a dog if ingested, but this is unlikely. If your dog weighs 10 pounds or less, ingesting a grape is cause for alarm. The bigger your dog is, the less likely it is that a single grape can be fatal. Grapes and raisins are poisonous to dogs and you should never let your dog eat either.

Again, it depends on a couple of factors such as the health, age, and immune system of the dog. Older dogs are usually more sensitive to grapes than young dogs.

Can dogs eat raisins?

No. Since raisins are dried grapes you should not give any to your dog. This concept also applies to all varieties of grapes like red grapes, concord, currants, sweet jubilee, etc.

Moreover, you should always check the ingredients of any food that you are giving to your dog. If it includes grapes then don’t think twice and abandon the idea of giving it to your dog.
