Can dogs eat garlic?
Garlic is toxic to dogs, though less potent than onions. Small amounts may not cause immediate symptoms, but regular consumption damages red blood cells.
Garlic belongs to the allium family along with onions, leeks, and chives. It contains thiosulfates that damage dogs' red blood cells, leading to hemolytic anemia. Garlic is approximately 3-5 times more concentrated than onions.
While some holistic pet sources claim garlic has health benefits for dogs, veterinary science confirms it is toxic. The toxic dose is approximately 15-30 grams per kilogram of body weight, meaning a few cloves could affect a small dog.
Garlic powder and garlic salt are more concentrated than fresh garlic and therefore more dangerous per amount. The toxicity is cumulative, so even small daily amounts in food can build up over time.
Symptoms if ingested
- Vomiting and diarrhea
- Lethargy and weakness
- Pale gums
- Dark or red-tinged urine
- Elevated heart rate
What to do
If your dog ate a significant amount of garlic (more than one clove for a small dog), contact your vet. They may monitor red blood cell counts over the following days. For small incidental exposure in food, monitor for symptoms.
