Chocolate contains theobromine, a compound that is a cardiac stimulant and a diuretic. When affected by an overdose of chocolate, a dog can become excited and hyperactive. Due to the diuretic effect, it may pass large volumes of urine and it will be unusually thirsty. Vomiting and diarrhea are also common. The effect of theobromine on the heart is the most dangerous effect. Theobromine will either increase the dog’s heart rate or may cause the heart to beat irregularly. Death is quite possible, especially with exercise. Symptoms of chocolate poisoning include: vomiting, diarrhea, tremors, hyperactivity, irregular heartbeat and seizures.

Larger quantities of chocolate can poison or even kill a medium or large dog. An ounce or two of chocolate may not seem like much but it can be lethal to a small dog that weighs 10 lbs. or less. After their dog has eaten a large quantity of chocolate, many pet owners assume their pet is unaffected. However, the signs of sickness may not be seen for several hours, with death following within twenty-four hours.

Cocoa powder and cooking chocolate are the most toxic forms. These forms of chocolate contain ten times more theobromine than milk chocolate. Even licking a substantial part of the chocolate icing from a cake can make a dog sick. The next most dangerous forms are semi-sweet chocolate and dark chocolate, with milk chocolate being the least dangerous. A dog needs to eat more than a 250gm block of milk chocolate, however the high amount of fat found in milk chocolate can lead to an attack of pancreatitis.

* 1 ounce per pound of body weight (2 ounces per kg of body weight) for milk chocolate.
* 1 ounce per 3 pounds of body weight ( 1 ounce per 1.5 kg body weight) for semi-sweet chocolate
* 1 ounce per 9 pounds of body weight ( 1 ounce per 4 kg) for baker's chocolate.

Hopefully that helps! It doesn't sound like your pup will be in trouble, but if any of the above symptoms appear I'd get him to a vet.
