Why is dark chocolate more dangerous than milk chocolate for dogs?

The toxicity of chocolate is determined by its concentration of theobromine. Dark chocolate and baking chocolate contain significantly higher levels of cocoa solids, meaning they have a much higher concentration of theobromine per ounce compared to milk chocolate. Even a small amount of high-quality dark chocolate can be fatal to a small or medium-sized dog, whereas the same amount of milk chocolate might only cause digestive upset.

How long after eating chocolate will a dog show symptoms?

Symptoms of chocolate poisoning typically begin to appear within 6 to 12 hours after ingestion. However, because theobromine has a very long half-life in dogs, the symptoms can last for several days. Early signs often include extreme thirst, pacing, and vomiting, which can quickly progress to heart arrhythmias and muscle tremors if left untreated.
