What if a Toy Poodle eats a little white chocolate?

A little white chocolate may poison a Toy Poodle – studies show about 1276 g per kg of body weight causes mild signs like fast heart, nervousness, and excited barking; over 2551 g causes severe poisoning with cardiac arrest, pain, vomiting, fever, and death.

If it ate only a tiny bit with no signs, keep observing and give more water; if signs appear, take it to the vet at once.
