Project Description
When ingested, the Allium species of plants can cause gastrointestinal irritation and can also lead to damage of red blood cells. Members of this species include onions, garlic, chives and leeks.
No matter the state of the Allium (cooked, dried, processed or spoiled) the toxicity concern remains. Please note that onion powder, sometimes used in homemade pet diets, is included in this category. While the occasional low dose of these products (found in some pet foods or treats) will not likely cause toxicity, it is extremely important that you limit your pets intake of these foods.
In addition to dogs and cats, birds are also indicated for this toxicity.
Signs and symptoms of toxicity: vomiting, diarrhea, lethargy, difficulty breathing, rapid heart beat, refusal to eat, and oral/esophageal/gastric pain. Signs may not occur until several days after ingestion.
Toxic Consumption: Toxicosis may occur if 0.5% or more of the animal’s body weight is ingested.
