#1 Dog Garlic Toxicity Calculator – How Much Garlic Is Toxic to Dogs

Dog Garlic Toxicity Calculator

This dog garlic toxicity calculator have the ability to calculate garlic toxicity levels in dogs of all breed.

It can help pet owners determine if the amount ingested is a concern, and to assess the risks and steps to take if garlic ingestion occurs.

Garlic can be toxic to canine when ingested in large quantities.

Garlic contains compounds called thiosulphates which can cause gastrointestinal issues and red blood cell damage in dogs.

The toxicity depends on the amount of garlic ingested relative to the dog’s body weight.

This tool provides information on determining garlic toxicity levels in dogs and steps to take if garlic ingestion occurs.

Dog Garlic Toxicity Calculator

Garlic Toxicity Calculator

Use below garlic toxicity calculator to determine garlic toxicity level in your dog.

  • The toxic dose of garlic for dogs is 15 grams of garlic per kilogram of body weight.
  • The serious toxicity dose of garlic for dogs is 30 grams of garlic per kilogram of body weight.
  • A medium clove of garlic weighs about 5 grams.

For example, if a dog weighs 10 kilograms and eats 10 grams of garlic, the garlic toxicity is:

Garlic toxicity (grams)=10×0.015×1000=150

This means that the dog has ingested the toxic dose of garlic and may experience symptoms such as vomiting, diarrhea, weakness, and pale gums. If the dog eats more than 20 grams of garlic, the garlic toxicity is:

Garlic toxicity (grams)=10×0.03×1000=300

This means that the dog has ingested the serious toxicity dose of garlic and may suffer from severe anemia, kidney damage, collapse, or even death. See our Dog Chocolate Toxicity Calculator.

Garlic can be poisonous and potentially deadly to dogs if ingested in large amounts. Allium species including garlic, onions, chives and leeks contain thiosulphates, which are toxic to dogs.

Garlic is a common ingredient used in many foods. It adds great flavor to dishes and provides health benefits to humans.

The sulfur compounds in garlic damage red blood cells leading to anemia in dogs. Garlic also causes gastrointestinal issues like vomiting and diarrhea.

The toxicity level depends on the amount of garlic ingested and the dog’s body weight. Small ingestions may cause mild stomach upset, while large ingestions can be fatal. Check out Dog Raisin Toxicity Calculator.

Calculating Garlic Toxicity Levels

Calculating Garlic Toxicity Levels

What is the toxicity level of garlic? A dog garlic toxicity calculator allows you to input specifics to determine toxicity. You will need:

  • Dog’s weight – enter your dog’s weight in pounds (lbs)
  • Amount of garlic ingested – enter the approximate amount of garlic your dog ate in ounces (oz) or grams (g)

Some calculators may also ask for:

  • Garlic type – powdered, raw clove, cooked
  • Dog’s age – puppies are more susceptible

With this information entered, the calculator will provide toxicity levels and risk indications.

Toxicity Level Results

  • Safe – Minor gastrointestinal upset possible
  • Mild toxicity – Gastrointestinal upset likely
  • Moderate toxicity – Gastrointestinal and blood issues possible
  • Severe toxicity – Blood abnormalities and anemia likely
  • Potentially lethal – Seek emergency vet care immediately

Higher weights and small ingestions generally indicate safe or mild toxicity. Lower weights and large ingestions increase toxicity levels entered. Test our new tool at Yorkie Years to Human Years.

General garlic toxicity thresholds based on ingestion amount are:

  • Up to 0.5% of dog’s body weight – Likely safe
  • 0.5% to 0.9% of body weight – Mild toxicity
  • 1% to 1.5% of body weight – Moderate toxicity
  • 1.5% to 2% of body weight – Severe toxicity
  • Over 2% of body weight – Potentially lethal toxicity

For example, a 20 lb dog would experience:

  • Up to 0.1 oz garlic – Likely safe
  • 0.1 to 0.18 oz – Mild toxicity
  • 0.2 to 0.3 oz – Moderate toxicity
  • 0.3 to 0.4 oz – Severe toxicity
  • Over 0.4 oz – Potentially lethal

Puppy or Small dogs under 10 lbs should only ingest trace amounts. Speak to your vet for exact safe thresholds based on your dog’s unique factors.

How Long After Eating Garlic Will a Dog Get Sick

If a dog consumes a large quantity of garlic relative to their size, symptoms may begin within 2-3 hours. With smaller, limited amounts, it may take 24-48 hours before any effects are seen.

Some of the earliest indicators of garlic poisoning include gastrointestinal signs like vomiting, diarrhea, and abdominal pain. Lethargy and increased heart rate may also be noticeable early on. As toxicity increases, more concerning symptoms often develop.

Within 12 hours of ingestion, a doggie may begin showing pale gums, dark urine, labored breathing, or loss of appetite. These are signs of anemia and organ issues requiring prompt veterinary treatment.

Severe symptoms like collapse, seizures, or bloody stools tend to occur after 12-24 hours. However, the timelines can vary dramatically based on the dog and amount consumed.

No matter when symptoms start, get veterinary care immediately if you suspect garlic poisoning.

Quick action provides the best prognosis, especially within the first few hours after ingestion. Do not wait to see if your hound improves without treatment. With appropriate therapy guided by a veterinarian, most domestic dogs fully recover after garlic toxicity.

Dog Garlic Toxicity Symptoms

What does garlic poisoning look like in dogs? Look for the following signs if you suspect garlic toxicity:

  • Vomiting
  • Diarrhea
  • Abdominal pain, nausea
  • Weakness, lethargy
  • Rapid breathing
  • Increased heart rate
  • Red or brown urine
  • Pale gums, mucous membranes

Garlic ingestion can cause a range of symptoms in dogs. Vomiting and diarrhea are common signs. Abdominal pain and nausea may also occur. Dogs may become lethargic or weak if they ingest too much garlic.

An increased heart rate and heavy panting or rapid breathing can happen as well. Dogs may have pale gums after eating garlic. Their urine may become a dark or bloody color. Loss of appetite and tremors are also possible. In severe cases, seizures may occur.

The symptoms can show up within a few hours if a large amount was eaten. Smaller amounts could take 24-48 hours. Some of the most urgent symptoms requiring emergency vet care are pale gums, severe lethargy, dark urine, tremors, seizures, breathing issues, and an elevated heart rate.

The compounds in garlic damage red blood cells leading to anemia. This causes the gums and membranes to become pale. Vomiting and diarrhea are from irritation of the stomach and intestines.

If you see any signs of garlic poisoning, contact your vet immediately or go to an emergency clinic. Quick treatment leads to better recovery. Monitor your dog closely and don’t wait to see if symptoms worsen. With timely vet care, most dogs recover well if garlic toxicity is addressed early on.

How to treat garlic poisoning in dogs?

Take quick action if you know or suspect your dog ingested garlic:

  1. Determine approximate amount eaten
  2. Use toxicity calculator to establish risk
  3. Call your vet for guidance based on toxicity level
  4. Monitor for any symptoms next 12-24 hours
  5. Go to emergency vet at any sign of severe symptoms
  6. Bring label or garlic types eaten to the vet

If you suspect your dog has ingested a toxic amount of garlic, immediate veterinary treatment is crucial. Call your vet or emergency clinic without delay if your dog shows any symptoms of garlic poisoning or you know they ate garlic.

Your vet will likely recommend inducing vomiting if the ingestion only occurred within the last 2 hours. This helps eliminate some of the garlic before it can be absorbed. Only induce vomiting if your vet advises it. They will provide the correct dosage of hydrogen peroxide to give your dog.

If vomiting is not recommended, your vet may give activated charcoal to absorb toxins internally. They will also provide IV fluids and injectable medications to control vomiting and diarrhea.

Blood tests will be run to check for anemia and identify any blood cell abnormalities or organ issues. Your dog may need a blood transfusion if their red blood cell counts are very low.

Your vet will monitor your dog closely for the next 24-48 hours in the hospital. Supportive care like medications, IV fluids, and oxygen therapy may be used to manage any complications. With aggressive treatment from the start, dogs have an excellent chance of full recovery.

Follow your vet’s home care instructions carefully once released. Return immediately if any symptoms recur. Prompt veterinary treatment is the key to successfully overcoming garlic poisoning.

How to Stop Your Dog From Eating Garlic

  • Store garlic out of your dog’s reach, such as in a high cabinet or pantry they cannot access. Keep garlic powder and garlic supplements locked away as well.
  • Avoid feeding your dog any foods that contain garlic as an ingredient. Read all food labels carefully before giving people food to your dog.
  • Do not add garlic powder or use garlic-infused oils when cooking food for your dog. Stick to plain, dog-safe ingredients.
  • Supervise your dog when outside in the yard or on walks. Look for any stray bits of garlic, onion or chives they may try to eat.
  • Cover your compost pile if you throw vegetable peels in it. Dogs may be tempted to dig in the compost looking for scraps.
  • If you grow garlic or chives in your garden, consider fencing those areas off so your dog cannot access and eat the plants.
  • Train your dog to “leave it” and reward them for avoiding garlic items you point out. Practice this using negative reinforcement.
  • Educate any pet sitters, dog walkers or visitors about keeping garlic safely away from your dog.
  • If you suspect your dog ingested garlic, call your veterinarian or pet poison helpline immediately for advice.

Being diligent about keeping garlic completely away from your dog is key. Just a small amount can cause toxicity, so prevention is crucial.

Expert Advice on Garlic Toxicity

Here are some quotes from veterinary experts on mitigating garlic toxicity risks:

“Pet owners need to be aware of the potential toxic effects of garlic in dogs. Prevent access whenever possible and contact your vet immediately if ingestion is suspected.” – Dr. Mike Jones, DVM

“Even small amounts of garlic can cause toxicity when ingested by dogs. Have an emergency action plan in place if exposure occurs.” – Dr. Anne Sanders, Veterinary Toxicologist

“Monitor for symptoms like vomiting, lethargy or fast breathing for at least 24 hours following suspected garlic ingestion. Seek emergency care if these or other serious symptoms develop.” – Dr. Heather Long, Emergency Veterinarian


A dog garlic toxicity calculator can help assess the risks if your dog ingests garlic. While tiny amounts may just cause stomach upset, larger ingestions can be extremely dangerous and even fatal. Prevent access, know the toxicity thresholds, and act quickly if ingestion occurs. With prompt veterinary treatment guided by toxicity levels, outcomes can be positive even with moderate to severe poisoning. Keep your companion safe by understanding garlic risks and having a plan if accidental exposure occurs.
