The Short Answer
No. Garlic is more toxic than onions per gram. Worth avoiding completely.
Why Garlic Is Dangerous
Garlic is in the Allium family with onions, leeks, and chives. Same toxicity mechanism, but 5x more potent gram-for-gram.
Same disulfide compounds as onions cause oxidative damage to red blood cells. Garlic concentrates more of these compounds in less mass. A single clove can be problematic for a small dog.
Toxic Threshold
About 1 gram of garlic per 5 lbs of body weight is mildly toxic. A 15-lb Milo could be affected by ~3g (one clove).
Symptoms to Watch For
- Pale gums
- Lethargy
- Vomiting
- Diarrhea
- Loss of appetite
- Rapid breathing
- Brownish urine

The Dog Dad Take
Yes, some 'natural' flea-repellent blogs recommend garlic. They are wrong. The therapeutic window is too narrow to dose safely at home.
