Why Are Leeks Toxic To Dogs?

chopped_leek

Vegetables in the allium family (leeks, onions, garlic, shallots, and chives) contain n-propyl disulfide. This is the principal toxin that can cause anemia in dogs (link). 
N-propyl disulfide damages the red blood cell, reducing the amount of oxygen they can carry. It can also cause the red blood cells in your dogs’ body to rupture. The compound tricks the cells into thinking they are invaders, therefore, destroying them, which results in anemia.
It is thought that all parts of the vegetable are dangerous to dogs.
It is not known with leeks how much cause anemia, but with onions (also allium), it has been shown that around 0.5% of a dogs’ body weight would need to be consumed to show hematologic changes (link). 
This can be in one large dosage, or smaller amounts consumed over several days.
Garlic is thought to be up to 5 times more potent than onion and leeks. Again, this is dependant on the breed (certain breeds, such as Japanese breeds, like Akitas, are thought to be more sensitive), as well as weight and size (link) (link).

Fortunately, if your dog is treated quickly, allium poisoning is rarely fatal.
Usually, your vet will examine your dog, checking their weight, eyes, gums, temperature, heart rate, blood pressure, and other vital signs on arrival.
They will usually induce vomiting in an attempt to remove the onion, garlic, leek, chive, or shallot. Usually, they will administer a charcoal paste, which should help to absorb any remaining toxin left after vomiting.
Occasionally your dog may need a blood transfusion.
Your vet may also ask you to return after treatment for a blood test to check everything is back to normal.

 

How Do I Stop My Dog From Eating Leeks?

Those puppy eyes are irresistible, and sharing your food is one of the pleasures of having a dog. Unfortunately, some food that is delicious and sometimes nutritious to us can be deadly to dogs. Make sure to check what you are feeding your dog is safe before doing so. Check out our list of Foods Suitable For Dogs here. 

 

Keep The Leeks Away - All toxic food should be kept well out of dogs’ reach. Keep the cupboards and the pantry securely shut. This includes spices, as garlic and onion powder are also unsafe for dogs. Keep your dog out of the kitchen when left unattended.

 

Train Them Not To Beg For Food - Food often falls on the floor, especially if you have children. Teaching your dog not to linger underneath the table while you’re eating will help avoid any accidental ingestion of toxic food. 
We recommend using a bed or mat to teach your dog that when you’re sitting around the table that they stay there. This can take time, your dog will need to learn the WAIT or STAY command. You may also need to put your dog onto the mat several times during the meal at first, stay patient, and consistent. 
This can be challenging for dogs who scavenge and are rewarded for it (by receiving scraps). You can use chews or interactive toys (like a KONG or lick mat) to distract them too. 

 

Do Not Feed Your Dog Leftovers - Many foods from our plates can contain ingredients that are not necessarily safe, beneficial, or healthy to dogs. We advise not feeding your dog leftovers as they can cause serious health issues (such as obesity, dental problems, and salt poisoning) as well as toxicity.

 

There are many dog safe people foods, like carrots, apples, rice, eggs, chicken, which can be given to your dog as an occasional treat, this should be specially prepared for your dog.
Treats should only make up 10% of your dogs’ diet. 
Dogs do not need scraps. Their regular food should contain everything they need.  
Overall, make sure you know what is dangerous for dogs and keep it out of reach. 
Accidents do happen, make sure to have the poison helpline number available for emergencies and your local 24 hr veterinarian practice. 

 

Other Food Which Is Safe For Humans But Fatal To Dogs

chocolate

Chocolate - Dogs cannot process chocolate as it contains the chemical theobromine as well as caffeine. Dogs are far more sensitive to both compared to humans. It acts as a stimulant. Symptoms of poisoning include gastric upset, thirst, inability to settle or restlessness, and in more severe cases, tremors, seizures, and heart failure.
Grapes and Raisins - It is unknown which toxin and what quantity makes grapes so deadly to dogs. Some dogs can eat dozens and have no effects, and others can die from just one. Grapes and raisins can cause acute kidney failure. Symptoms include gastric upset, excessive drooling, lack of appetite, and abnormal drinking and urinating.
Macadamia Nuts - Why macadamia nuts affect dogs so badly is unknown. However, they can cause serious health issues. There is also no known quantity, and even a small amount has been known to cause effects. The most common symptom is a weakness in the back legs or inability to walk.
Caffeine - Dogs are far more sensitive to caffeine than humans. Symptoms can include heart palpitations, hyperactivity or restlessness, seizures, and muscle tremors. Keep your coffee and energy drinks to yourself.
Xylitol - This is an artificial sweetener that a dogs’ body confuses for real sugar. This causes the body to release a large amount of insulin when ingested by dogs. This can cause a considerable drop in sugar, leading to hypoglycemia. Even small amounts can make a dog sick.
