Why is chocolate dangerous for dogs to eat?
In: Canine Health

Answer

While the pathetic begging look that goes across the face of a dog wanting chocolate can weaken the most stoic dog owner, stay firm. Do not give in. Ever.

Once dogs have tasted chocolate, they want more.

And for dogs, that's a bad thing.

You might disagree, thinking back to a time when you noticed a dog enjoying a tidbit of chocolate with no deleterious effect.

Don't be fooled.

The problem, according to veterinary experts, is that eating a speck of chocolate leads a dog to crave more. It can mean that your dog will jump at a opportunity to get any type of chocolate, not knowing that certain chocolates are more lethal than other types. Larger amounts of chocolate, particularly of the most toxic type, can bring about epileptic seizures in some dogs, and in all dogs, can kill.

Poisoning of dogs by chocolate is not as uncommon as you might think.

"Chocolate ingestions are one common reason why pet owners and veterinarians call us," said Dana Farbman, Certified Veterinary Technician and Manager, Client and Professional Relations, ASPCA Animal Poison Control Center. "However, it would be difficult to verify an exact ranking in frequency of calls, as the types of substances we receive calls on can vary greatly depending on many factors, including the time of year. We generally do experience somewhat of a rise in chocolate calls around holidays, such as Halloween, Easter, Christmas, Valentine's Day and Mother's Day.

Why is Chocolate Lethal?

Chocolate contains theobromine. A naturally occurring stimulant found in the cocoa bean, theobromine increases urination and affects the central nervous system as well as heart muscle. While amounts vary by type of chocolate, it's the theobromine that is poisonous to dogs.

Symptoms of Chocolate Dog Ingestion and Poisoning

You can recognize that your dog has eaten a toxic dose of chocolate from the symptoms. Within the first few hours, the evidence includes vomiting, diarrhea or hyperactivity. As time passes and there's increased absorption of the toxic substance, you'll see an increase in the dog's heart rate, which can cause arrhythmia, restlessness, hyperactivity, muscle twitching, increased urination or excessive panting.

This can lead to hyperthermia, muscle tremors, seizures, coma and even death.

How Much Chocolate Is Deadly?

If a 50-pound dog eats a teaspoonful of milk chocolate, it's not going to cause serious problems. However, if that same dog gorges himself on a two-layer chocolate cake, his stomach will feel more than upset and soon it's likely he'll be vomiting or experiencing diarrhea.

To answer the question "How much is too much" is not simple. The health and age of your dog must be considered. Obviously if your dog is aged and not in top shape, his reaction to a plate of chocolate is going to be different from a young healthy dog of the same weight.

Another fact that must be considered is this: Not all chocolate is the same. Some has a small amount of theobromine; another type has a large amount and still another contains an amount that is somewhere in between. The quantity has a relationship with the weight of your dog. Small dogs can be poisoned, it is easy to understand, from smaller amounts of theobromine than large dogs.

Which chocolate is the safest, relatively speaking? White chocolate. It has the least amount of theobromine: 1 mg per ounce. Far on the other side of the spectrum is baking chocolate, which has a huge 450 mg of theobromine per ounce!

Here are a few other chocolates for you to ponder: hot chocolate, 12 mg of theobromine per ounce; milk chocolate, 60 mg/oz; and up there near baking chocolate: semi-sweet chocolate with 260 mg/oz.
