A closer look at flan
Eggs, condensed milk and a caramel layer, making it one of the sweetest and most lactose-dense desserts on a dinner table, in a texture dogs swallow fast. The details below use the specific facts for this exposure, rather than treating it like every other food question.
1. Start with the exact exposure
For a closely related comparison, read Custard. No toxic threshold. The concentrated milk and sugar are what cause the upset, and a small dog reaches that point on a much smaller slice.
2. Use the facts to decide whether to monitor or call
Another helpful reference is Sweetened Condensed Milk. A forkful in a healthy large dog is usually uneventful. Watch for the caramel sticking to teeth as much as the stomach upset. Repeated vomiting, a diabetic dog, or a dog with a pancreatitis history.
3. If the details are uncertain
Follow the first 10 minutes guide. Offer water, hold off on further treats, and call if vomiting repeats.
