Dog Ate Garlic: What to Do, Symptoms, and When to Seek Care

If your dog ate garlic, it’s important to take it seriously. Garlic is toxic to dogs and can damage red blood cells, leading to a condition called hemolytic anemia.

Even though garlic is sometimes thought to be less harmful than onions, it is actually more concentrated and can be just as dangerous.

What to Do If Your Dog Ate Garlic

If your dog has ingested garlic, take these steps right away:

• Remove any remaining garlic so your dog cannot eat more
• Identify the form (raw, cooked, powder, supplement, or mixed in food)
• Estimate how much your dog ate
• Note your dog’s weight and the time of ingestion
• Call a veterinarian for guidance

Is Garlic Toxic to Dogs?

Yes, garlic is toxic to dogs. It belongs to the Allium family and contains compounds that damage red blood cells, reducing oxygen delivery throughout the body.

Garlic is more concentrated than onion, meaning smaller amounts can still cause toxicity, especially with repeated exposure.

Symptoms of Garlic Toxicity in Dogs

Symptoms may be delayed and can appear several days after ingestion. Common signs include:

• Lethargy
• Weakness
• Pale gums
• Decreased appetite
• Vomiting or diarrhea
• Rapid breathing
• Dark or reddish urine

As red blood cell damage progresses, anemia can become severe.

When Should You Call a Veterinarian?

You should contact a veterinarian if:

• Your dog ate any amount of garlic
• You are unsure how much was consumed
• Your dog is showing any symptoms
• Exposure happened repeatedly over time
• Your dog is small, a puppy, senior, or has underlying conditions

Even if your dog seems normal, early evaluation is important.

How Vets Treat Garlic Toxicity

Treatment depends on the amount ingested and how quickly your dog is seen.

Treatment may include:

• Inducing vomiting if ingestion was recent
• Activated charcoal in some cases
• Bloodwork to monitor red blood cell levels
• IV fluids and supportive care
• Oxygen support in more severe cases
• Blood transfusion if anemia becomes severe

Early treatment helps reduce the risk of complications.

This level of care must be provided by an emergency or urgent care veterinary hospital, as AnimALL Mobile Veterinary Service is not able to provide emergency treatment.

What to Do Next

Garlic toxicity can be delayed and worsen over time. If your dog has eaten garlic, it’s best to have them evaluated, even if symptoms haven’t appeared yet.

Contact ASPCA Animal Poison Control at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661 for guidance, then take your dog to your nearest emergency or urgent care veterinarian for treatment.

If your pet is showing signs of a life-threatening emergency, please go directly to the nearest emergency veterinary hospital rather than waiting for a mobile appointment.
