Why is chocolate bad for dogs?

Chocolate is harmful to our dog’s health because it contains a little caffeine and a lot from a chemical called theobromine, which is similar to it. Both chemicals are poisonous for dogs(and cats as well) and are used medicinally as a diuretic, heart stimulant, blood vessel dilator, and smooth muscle relaxant for humans.

Unlike humans, most pets' s but especially dogs' organs can’t metabolize theobromine so easily. They process it much more slowly, which makes them more sensitive to the chemicals’ effects and can easily build up to toxic levels in their system it is very toxic for their nervous system as well.

With large amounts, theobromine can produce muscle tremors, seizures, an irregular heartbeat, internal bleeding, or a heart attack. The onset of theobromine poisoning is usually also marked by restlessness.

But vomiting, diarrhea, increased thirst, hyperactivity, excessive urination, and a racing heart rate are common symptoms of theobromine poisoning.

In more serious cases, (at doses over 50 mg/ kg ) they can experience muscle tremors, seizures, and heart failure as well. A larger amount of dark chocolate especially for pets with pre-existing heart disease can even cause cardiac arrest and sudden death.
