1, dogs can't eat chocolate, because chocolate is toxic to dogs, but many dogs who have eaten a small amount of chocolate have no adverse effects. This is because of the dose of poisoning dogs. The ingredients in chocolate that are toxic to dogs are theobromine and caffeine. These two compounds are almost identical in structure and belong to the same chemical called methylxanthine. Part of the reason why methylxanthines are so dangerous to dogs is that their metabolism of caffeine and theobromine is very weak.

2. The concentration of caffeine in a dog's serum will reach a peak within 30-60 minutes after eating chocolate, and then half of the intake dose will be eliminated within 4.5 hours, then it will reach a normal level after 10 hour, and finally the remaining half of caffeine will be eliminated after taking chocolate 17.5 hours. Of course, if the dose exceeds the standard, then the dog will be dead within 30-60 minutes.

3. Methylxanthine is a stimulant for human beings, which can resist the activation of adenosine receptors-it is precisely because of these glands that we feel sleepy and reduce our physical activity. Methylxanthine inhibits these drowsy feelings and thus acts as a stimulant, so many people drink coffee to refresh themselves and eat chocolate to refresh themselves. These stimulants are equally effective for dogs. After eating theobromine and caffeine, dogs will feel nauseous, even vomit, have rapid heartbeat, diarrhea and mania. If they take too much methylxanthine, they will have epilepsy, panic and even death.
