Can a West Highland White Terrier Eat Garlic?

Verdict: ❌ NO

Why Garlic is Dangerous for Westies

Garlic belongs to the Allium family (along with onions, leeks, and chives). It contains a compound called thiosulfate, which is toxic to dogs.

Unlike humans, dogs cannot properly process thiosulfate. When ingested, this compound causes oxidative damage to the red blood cells, leading them to rupture. This can result in a serious condition known as hemolytic anemia.

While some owners claim their dogs “handle” small amounts of garlic, the risk is not worth the reward—especially for smaller breeds like the West Highland White Terrier, where toxicity can occur more quickly due to their lower body mass.


Potential Risks & Symptoms

If your Westie consumes garlic, the effects may not be immediate. Toxicity often develops slowly over several days. Watch for these warning signs:


What to Do If Your Westie Ate Garlic

If your West Highland White Terrier has accidentally ingested garlic or a product containing garlic powder (which is more concentrated and dangerous), follow these steps:

  1. Remove the Source: Immediately take away any remaining food.
  2. Assess the Amount: Note how much was eaten and when. Garlic powder is significantly more potent than fresh garlic.
  3. Call Your Vet: Contact your veterinarian or a Pet Poison Helpline immediately. They may advise you to induce vomiting or bring the dog in for monitoring.
  4. Monitor Behavior: Keep a close eye on your dog’s energy levels and gum color for the next 48–72 hours.
  5. Blood Tests: If toxicity is suspected, your vet can perform a CBC (Complete Blood Count) to check for anemia.
