If your dog has eaten something toxic, contact your veterinarian or an emergency animal hospital right away. Do not wait for symptoms. In the US you can also call the ASPCA Animal Poison Control Center at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661 (fees may apply).
Why
Like onions, garlic contains sulfur compounds that damage red blood cells and can cause anemia. Garlic is generally considered more potent than onion, so a smaller amount can cause harm.
Garlic powder, garlic salt and garlic supplements are concentrated sources. You may see claims that garlic prevents fleas; there is no good evidence for this, and it is not worth the risk.
Symptoms to watch for
- Weakness and lethargy
- Pale gums
- Fast breathing
- Red or brown urine
- Vomiting and stomach upset
- Signs of anemia can be delayed by several days
What to do if your dog eats it
- Call your veterinarian and describe what your dog ate, including sauces or seasonings.
- Check ingredient lists of treats and human foods for garlic or garlic powder.
- Never give garlic supplements unless your veterinarian specifically recommends them.
