The leaves can be eaten if they are boiled in water to decrease the level of oxalate toxicity. The garden sorrel contains oxalates, and can affect the gastrointestinal tract of individuals. Oxalates are also toxic to dogs, and the amount of oxalates, including raphides, in the sorrel plant depends on the concentration of the leaves and stems.
The plant can affect dogs’ if ingested, due to the insoluble calcium oxalates within the parts of the plant. Garden sorrel does not have as high of a concentration of these crystals as many other toxic, raphide-containing plants, but can cause irritation and pain when ingested by dogs in large amounts.

He may immediately begin administering fluids to your dog, in addition to thoroughly rinsing and decontaminating his face and mouth of the toxic chemicals of the plant.
Your veterinarian will perform a complete physical examination. He will conduct blood work, urinalysis, and a biochemistry profile. He may also want to take a sample of his stomach contents. Once the testing comes back, your veterinarian will understand the level of toxicity your dog has in his system. Your medical professional may also evaluate his kidney function, which may be revealed in the biochemistry profile and urinalysis, to be sure your dog’s kidneys are not in danger of failing.

Your veterinarian will immediately administer fluids to your dog to help him flush out the toxins from the plant. In these fluids he may also add an antihistamine to counteract the histamines released by the raphides.
Emesis may be performed if the veterinarian feels it is safe to do so. This depends on the level of toxicity and if he feels the dog does not have a risk of asphyxiation. If there is a risk, a stomach tube may be placed instead to flush out the contents of the stomach. This procedure may be followed by a few doses of activated charcoal to help further absorb the toxic chemicals.
Your dog may be kept overnight or for a few nights to be observed by the veterinarian. In doing so, he may continue the fluid therapy and monitor his vital signs, such as heart rate, kidney function, urination, blood pressure, and any other bodily system to be sure he is beginning to recover.
