Humans love chocolate, but for dogs, it is deadly. It will come as no surprise to many pet owners that a small amount of chocolate is very dangerous for your furry companion. Even though it might seem innocuous to let your dog take a small nibble from your favorite chocolate bar, if you give in your dog will pay the price. Chocolate poisoning in dogs is a common pet emergency that must be treated immediately. Knowing why chocolate is toxic, knowing the signs of dog chocolate toxicity, awareness of prevention methods and ways of limiting accidental ingestion will allow you to keep your pet safe.

Why is Chocolate Dangerous for Dogs?

Chocolate is toxic with theobromine and caffeine, which also occur in dogs. Dogs metabolize these substances a lot more slowly than humans can. The result is that their slow metabolism allows toxic levels to build up in their system with severe health problems as a result.

Although it varies depending on the type of chocolate, the amount consumed and the size of the dog, the severity of chocolate poisoning can be quite serious. Dark chocolate and baking chocolate have the highest theobromine content, so therefore, they are the most toxic.

How Much Chocolate is Toxic for Dogs?

The level of toxicity also depends on the amount and type of chocolate and the size of the dog. Smaller dogs stand a higher risk of being poisoned by even a small piece of chocolate because even a small piece of chocolate contains enough theobromine that can poison.

Mild poisoning can result from even a small dose of chocolate, while larger amounts will be fatal. That is why it is important to keep a dog away from any kind of chocolate.

Dog Poisoning Symptoms: How to Recognize Chocolate Toxicity

Early recognition of the signs of dog chocolate toxicity may save a dog’s life. Symptoms can develop within a few hours of ingestion and can worsen over time if treatment is not started quickly.

Early Signs of Chocolate Poisoning

Mild symptoms may begin to show in dogs two to four hours after eating chocolate. First signs include restlessness, excessive thirst, drooling and vomiting. Diarrhea may also develop in some dogs and if not treated within the earliest time, it may result into dehydration.

Severe Symptoms of Chocolate Poisoning

Symptoms become more serious as theobromine continues to build up in the dog’s system. An increased heart rate, muscle tremors, seizures, and breathing problems are among them. In the more extreme cases, chocolate poisoning can result in heart failure, coma, or even death.

Immediately veterinary care is needed if a dog shows any of those severe symptoms. The faster treatment starts, the greater the chance for recovery.

Nevertheless, correct administration should never be performed without proper guidance, since overdosage, not to mention overdose, can be more harmful than helpful.

Veterinary Treatment for Chocolate Toxicity

The dog may visit a veterinary clinic where it may receive treatments like activated charcoal to aid in the absorption of the toxins so they do not enter the bloodstream. In addition to doing so, the vet might give IV fluids to help flush out these toxins and keep the dog hydrated.
