Can a quarter of chocolate cupcake kill dog?

It depends on the size of the dog and the type of chocolate. Generally speaking, dark chocolate is more toxic to dogs than milk chocolate, and white chocolate is not toxic at all. The amount of chocolate that is toxic to a dog also depends on the dog's weight. A small dog may only need to eat a small amount of chocolate to become sick, while a large dog may be able to tolerate eating more chocolate without getting sick.

If you think your dog has eaten chocolate, it is important to contact your veterinarian immediately. The veterinarian will be able to determine if the amount of chocolate that your dog ate is toxic and will recommend treatment if necessary.

Some of the symptoms of chocolate poisoning in dogs include:

* Vomiting

* Diarrhea

* Increased thirst

* Increased urination

* Restlessness

* Hyperactivity

* Tremors

* Seizures

* Coma

If you see any of these symptoms in your dog, it is important to take them to the veterinarian immediately.
