My dog ate some of my bread with roughly 1 teaspoon of crushed garlic in it. She is a mastiff x ridgeback and is roughly 45kg. Is this poisonous?

Given Roxy's weight and the amount she ate, it may not be toxic to her, but as little as a clove of garlic can prove to be toxic to dogs. I would monitor her for signs of toxicity, which include drooling, nausea, vomiting, diarrhea, lethargy, abdominal pain, increased heart rate, weakness, exercise intolerance, collapse, and pale gums. It can take up to a couple of days for signs of garlic toxicity to show, so I monitor her for at least four days. If she shows any signs of toxicity, take her into a vet immediately. In the future, I would make sure Roxy doesn't eat anything with garlic in it.
