What To Do If your Dog Eats Grapes

Once you ascertain that your dog has eaten grapes, try to induce your dog to vomit before the grapes are digested and absorbed into the bloodstream.

Hydrogen Peroxide: Use a hydrogen peroxide solution to induce vomiting. The amount of solution you give to your dog should be directly proportional to its weight. That is one teaspoon per 5lbs of your dog’s body weight.

When you are trying to induce vomiting, be cautious. Also, make sure the number of teaspoons given at a time should not be more than 3. If the vomit delays for more than ten minutes repeat the procedure using the same dosage.

This process should not be carried out more than thrice and should be spaced with an interval of ten minutes.

If after inducing vomiting and nothing happens after the third time, stop using hydrogen peroxide. Don’t try out anything else without consulting a vet.

Also, don’t use a stronger solution without the vet’s consent and approval. Be cautious not to induce vomit without absolute surety that your dog ingested grapes or raisins.

Also inducing vomit should be spared in instances where your dog is having difficulty breathing, having severe distress, or is unconscious. Make sure you take your dog to the nearest vet whether he vomited or not.

Activated Charcoal: Other than hydrogen peroxide you can also use activated charcoal to prevent the toxin from being absorbed into the bloodstream. Before you administer the activated charcoal it is important to consult a vet on the amount to give your dog depending on the quantity of grapes that your dog ingested.

Since dogs respond differently to medication, it is important to take your dog to the vet for professional medical care.

These tests include a urinalysis, Serum Biochemistry Profile and Complete Blood Count (CBC). The urinalysis a vital tests as it helps assess the extent of kidney damage by the toxins from the grapes.

Sadly, there is no antidote for poisoning resulting from eating grapes.

Poisoning Treatment

Since there is no antidote, the vets reduce the absorption of the poison to reduce the amount of damage to your dog’s kidneys. The health damage can be controlled if the dog was checked as fast as it happened.

The vet will use activated charcoal to reduce the absorption of the poison and hydrogen peroxide to induce vomit. Your dog will then require intravenous fluids which are administered through a drip injection.

These fluids are vital in flushing out all the absorbed toxins before they damage the kidneys. Other drugs are administered to reduce the vomiting or nausea and also to regulate blood flow to the kidneys. The vet evaluates your dog’s response to the treatment. If the dog’s response to treatment is poor, the vet will use a more aggressive method of treatment.
