What happens if a puppy eats mango?

A little mango is usually fine, but its high sugar and fiber can cause indigestion if eaten in excess; give some probiotics to help. Some dogs are allergic, showing vomiting and diarrhea, and in severe cases breathing trouble or anaphylactic shock.

Without prompt treatment this can be fatal, so watch the puppy closely after feeding mango and take it to a vet if anything abnormal appears.
