Dogs and humans metabolize foods differently.
For this reason, some foods are safe for humans to eat but may be toxic and potentially deadly for dogs.
On the other hand, there are many human foods that are perfectly safe and even healthy for dogs to eat as an occasional treat.
This article gives an overview of 53 foods and whether or not your dog can eat them.
Both raw and cooked carrots are safe for your dog to eat.

This is because chocolate contains theobromine and caffeine, two stimulants that dogs cannot efficiently metabolize ().
If your dog eats chocolate, he may exhibit symptoms like vomiting, diarrhea and dehydration. These symptoms may lead to more serious complications, such as internal bleeding, muscle tremors, seizures and death ().
Darker and less sweet varieties of chocolate, such as cocoa powder and unsweetened baker’s chocolate, are more poisonous to dogs than sweetened varieties, such as milk chocolate.

Raw yeast dough is a concern because yeast cells produce alcohol as they ferment, which may lead to alcohol poisoning and death if your dog consumes it (, ).
Furthermore, dogs that eat raw yeast dough may experience severe bloating, as the dough expands in their stomachs. This can cause difficulty breathing and weakness ().
Dogs can eat bananas in moderation.
