PLEASE DON'T WORRY ABOUT YOUR GIRL!
lol, sorry, I don't mean to laugh. Every dog has a different tolerance level, but a lot of the people on this site seem to think that the tad bit she had will likely hurt her and the reality it, that's HIGHLY unlikely-even if she was a 2 lb Yorkie.
Here's a quote to ease your worries, but otherwise call your vet and hope he's actually up to date on his information!
"Dogs develop hemolytic anemia if they eat enough onions. I don't think that it matters too much
whether the onions are cooked or not. The quantity of onions required is high enough that dogs
can generally tolerate small doses of onions without any problem and moderate amounts of
onion without clinically apparent disease, even though there may be measurable changes on lab
test results. Cats are probably a little more sensitive to onion toxicity than dogs are. I can't find
an exact quantity of onions required to cause toxicity problems in dogs, but there are several
case reports of onion toxicity and they involve whole onions or sizable portions of chopped
onions (like a cup or more). I think that feeding dogs meat that has been cooked with onions is
pretty safe but you might want to avoid giving them the broth from around something like
pot-roast if there were a lot of onions used in the cooking, just to be safe.
Large amounts of garlic will produce similar toxicity problems in both dogs and cats. I think that
the amount required is not likely to be eaten by a cat but there are probably a few dogs who
would lap up a container of spilled garlic.
Among common foods, the only other significant toxicity that I can think of are recent reports of
toxicity from eating grapes and raisins that have been reported in dogs.
