My name is***** and I am sorry to hear that Angel is vomiting tonight. It sounds like she is decontaminating herself after eating the human food. This is very common in dogs and is a way to protect themselves from poison.
First- what breed is Angel? I just saw the second message that her stomach seems distended? Could she have Bloat?
If bloat is not what we are thinking for her-
Here is what I would do tonight-
-remove all food and water for at least 4 hours. Dogs will drink excessively after vomiting and it just makes them more nauseous.
-After she has stopped vomiting for 4 hours, you can offer very small (about 1/2 cup at a time) amounts of water once every 30 minutes.
-If she is able to hold this down overnight, you can give her a normal breakfast in the morning.
-If she continues to vomit overnight, she needs to see your vet first thing.
Does this help? What other questions do you have?
