#6 – Garlic
Consider your dogs vampires and keep them away from raw garlic as much as possible.
What's In It:
Like the chocolate rule, the stronger the onion the more toxic it can be. Since garlic is part of the onion family it's even more dangerous to dogs than onions per ounce. Garlic contains compounds that are strong in toxicity.
What It Can Do:
While the effect of garlic consumption to red blood cells won't appear for a few days in dogs, they'l be tired and reluctant to move. The dog's urine will be orange to dark red in color. Like with onions, a blood transfusion might be required in severe cases.
