Can dogs eat chocolate?
No. No. No. Three times, no. Chocolate contains substances called methylxanthines. They are harmless to humans but deadly dangerous for our beloved pets due to their different metabolism mechanisms.
The group of methylxanthines contains:
- Caffeine — Present in chocolate, coffee, or coffee beans. ☕
- Theobromine — Found in chocolates, desserts, sweets, puddings, and even ice cream. 🍩
The combined amount of these substances allows us to measure the deadliness of a given food, usually given in milligrams per kilogram.

How much chocolate can a dog eat?
Chocolate can be lethal to dogs. We definitely shouldn't give them even a little bit of it. Pets metabolize food in a different way than humans do.
Theobromine and caffeine are two substances that are deadly to them. It is generally believed that a combined dose of less than 15.01 mg/kg (7.5 mg/lb) shouldn't harm your dog.
This dose is equivalent to:
- 1 piece of dark-sweet chocolate for a 3 kg (6 lb) dog.
- 7 pieces of dark-sweet chocolate for a 15 kg (33 lb) dog.
Try our pet chocolate toxicity calculator to compute the doses for different kinds of chocolates, cakes, desserts, and coffee — specific for your pet's weight! ☕
How to calculate chocolate toxicity in dogs?
The first step of calculating toxicity is to know the concentration of the harmful substances in a given food. Our dog chocolate calculator is fully prepared for this task.
If you already have all the data you need, proceed to the calculations.
Theobromine dose = (Chocolate type × Amount eaten) / Weight
Caffeine dose = (Chocolate type × Amount eaten) / Weight
Total dose = Caffeine dose + Theobromine dose
We used all the equations presented above to create our pet chocolate calculator.
- Theobromine dose and Caffeine dose are given in mg/kg.
- Chocolate type means the concentration of theobromine/caffeine in 1 g of a given chocolate product.
- Amount eaten — Given in grams (g).
- Weight of the pet is given in kilograms (kg).
To evaluate the total toxicity, we need to use the Total dose that we've already calculated:
- A total dose of <15.01 mg/kg — Your pet's going to be ok.
- A dose between 15.01-34.02 mg/kg — Your pet may suffer from diarrhea and vomiting.
- A dose between 34.02-45 mg/kg — Your pet may also suffer from tachyarrhythmia (possibly dangerous, rapid heartbeat).
- A dose between 45-55.01 mg/kg — Will cause seizures and tremors.
- A total dose larger than 55.01 mg/kg — May kill your dog.
How much chocolate can a 70 lb dog eat?

Can dogs eat white chocolate?
Yes. This is not a risk of toxicity to your dog because it contains a very low level of caffeine and theobromine. Therefore, treatment is not required.
