The domesticated species commonly implicated in canine toxicity are Allium cepa (onion), Allium porrum (leek), Allium sativum (garlic), and Allium schoenoprasum (chive), with garlic being the most toxic.Any form of these vegetables and herbs can cause poisoning.Besides making your dinner taste great, onions, garlic, leeks and chives can cause serious medical problems for your dog.Although clinical signs of illness, such as vomiting, can occur soon after your dog eats any of these, the full onset of signs may take several days to appear.Kidney damage can occur in dogs that have red blood cell destruction.Most cases are diagnosed in pets that have the expected signs along with changes in the red blood cells and a known or suspected ingestion.If ingestion occurred within a few hours of treatment, the veterinarian may induce vomiting.Blood work to look at the red blood cells will also be performed.If you believe your pet ingested ibuprofen, it is important to call your veterinarian or Pet Poison Helpline, a 24/7 animal poison control center, at 1-800-213-6680 right away to have the risk of poisoning assessed.Pets that develop a low red blood cell count (anemia) may require oxygen supplementation or a blood transfusion.How can poisoning be prevented?Preventing access to plants, herbs, seasonings and supplements is key to avoid poisoning.Never give medications or supplements to a pet without first consulting a veterinarian.These items should not be left in areas where pets can get into them.Whenever a toxic exposure is suspected, immediate action is recommended. .

Can Dogs Eat Garlic? We've Got the Answer — American Kennel Club

According to the Merck Veterinary Manual, garlic and other members of the allium family, including onions, contain thiosulfate, which is toxic to dogs but not to humans.Symptoms of anemia include pale mucous membranes, rapid breathing, lethargy, weakness, jaundice, and dark colored urine.Garlic toxicity also causes symptoms of gastrointestinal upset, including vomiting, diarrhea, loss of appetite, abdominal pain, depression, and dehydration.Studies have found it takes approximately 15 to 30 grams of garlic per kilograms of body weight to produce harmful changes in a dog’s blood.To put that into perspective, the average clove of supermarket garlic weighs between 3 and 7 grams, so your dog would have to eat a lot to get really sick.If you want to give your dog a healthy treat, consider feeding him fruits and vegetables that are high in valuable nutrients, like apples, blueberries, strawberries, watermelon, carrots, cucumbers, and sweet potatoes. .

Toxicology Brief: Allium species poisoning in dogs and cats

Although marked Heinz body formation may be present within a day after onions are ingested, the anemic nadir typically develops several days later.Other types of oxidation of hemoglobin globin chains result in membrane cross-linking reactions and eccentrocyte formation.6 The formation of Heinz bodies and eccentrocytes increases erythrocyte fragility and extravascular hemolysis.Direct oxidative damage to the erythrocyte cell membrane and its sodium-potassium pump or the oxidative production of hemin also contributes to cell lysis.The primary toxicologic mechanism of Allium species-derived organosulfur compounds is oxidative hemolysis, which occurs when the concentration of oxidants in the erythrocyte exceeds the capacity of the antioxidant metabolic pathways.Catalase antioxidant activity in erythrocytes in dogs is low,3 and normal hemoglobin in cats is about two to three times more susceptible to oxidative damage than the hemoglobin in other species.4.Many of these compounds or their metabolites are responsible for the odors, flavors, and pharmacologic effects of these plants.The domesticated species commonly involved in toxicosis include Allium cepa (onion), Allium porrum (leek), Allium sativum (garlic), and Allium schoenoprasum (chive).All Allium species and the products derived from them can be toxic to dogs and cats1; however, relatively few Allium species are of important toxicologic interest.Allicin and ajoene, pharmacologically active agents in garlic, are potent cardiac and smooth muscle relaxants, vasodilators, and hypotensive agents.7-9 Also, ajoene and other organosulfur compounds derived from onions are potent antithrombotic agents.10 Thus, hypotensive and antithrombotic effects can exacerbate the physiologic effects of anemia and impaired oxygen transportation.Allium species toxicosis most commonly occurs after oral consumption.Dogs and cats are highly susceptible to onion toxicosis: Consumption of as little as 5 g/kg of onions in cats or 15 to 30 g/kg in dogs has resulted in clinically important hematologic changes.Other inborn errors in metabolism or nutritional deficiencies that result in decreased erythrocyte antioxidant defenses, such as glucose-6-phosphate dehydrogenase deficiency or zinc deficiency, could increase an animal's susceptibility to Allium species toxicity.13 Concurrent treatment with xenobiotics, drugs, or dietary factors that induce erythrocyte oxidative injury (e.g. propofol, propylene glycol, dl-methionine, sulfonamides, sulfapyridine, large doses of vitamin K3, benzocaine) or diminish erythrocyte oxidative defenses (e.g. acetaminophen) is likely to increase an animal's susceptibility to Allium species toxicosis.In dogs and cats, clinical signs of Allium species toxicosis may appear within one day of consumption if large amounts of material have been ingested; however, it is more common for clinical signs to develop after a lag of several days.Allium species toxicosis is typically diagnosed through a combination of history, clinical signs, and microscopic confirmation of a Heinz body-type hemolytic anemia.No specific antidote is available for Allium species toxicosis.Treatment involves gastrointestinal decontamination and removing the Allium species source, treating the anemia, and providing general supportive care.Antioxidants, such as sodium ascorbate, vitamin E, and N-acetylcysteine, have minimal overt protective effects in onion powder toxicosis in cats.14 Diets low in potential oxidants are recommended; semimoist foods that contain propylene glycol should be avoided, particularly in cats.15.Cope, BSc, BVSc, PhD, Department of Biomedical Sciences, College of Veterinary Medicine, Oregon State University, Corvallis, OR 97331.Hill AS, O'Neill S, Rogers QR, et al.

Poisonous Plants

Also, be advised that the consumption of any plant material may cause vomiting and gastrointestinal upset for dogs and cats.Plants listed as either non-toxic, or potentially toxic with mild GI upset as their symptoms are not expected to be life-threatening to your pets. .

Garlic Poisoning in Dogs

Some experts believe it is because of the high red blood cell count and lower levels of glutathione (tripeptide protein) and potassium, which is hereditary in these breeds.Garlic poisoning does major damage to the red blood cells, causes gastrointestinal upset (abdominal pain, nausea, vomiting, diarrhea), and respiratory problems.The sulphuric compounds in the garlic are absorbed into the gastrointestinal tract and changed into reactive oxidants, which damage your dog’s red blood cells. .
