Just wondering if my math is right each blox contains about 1.4mg of Bromadiolone? and bromadiolone is lethal at 10mg per 1 kg body weight? so a 10kg dog would need to eat roughly 70 blox to be fatal? 0.005% of (28 grams) = 1.4 milligrams
Each blox of Contrac is 28 grams which equal 2800mg. If your pet ate an actual blox, I wouldn't take the chance of figuring it out because the minimum amount could be lethal. It would be best to take your pet to the vet and have him/her take a look and/or administer the antidote which is Vitamin K1.
